Hello, I'm Frank Bright, Extension Assistant
for the Pesticide Safety Education Program.
Welcome to the Recertification
for the Right of Way category.
This training will help you prepare for vegetation control,
and rights of way.
Right of Way vegetation control goals
are to increase motorist safety,
remove vegetation hazards, and prevent damage to roadways.
Throughout this training, you will learn a variety of topics
from Nebraska Extension UNL specialists
and County Weed Superintendents.
You will cover a variety of topics including,
Right of Way application, general procedures, weed biology,
herbicide selection, noxious weeds,
integrated weed management, environmental considerations,
application equipment and calibration
and consideration of herbicide sensitive sites.
I'm Rob Schultz with the Hall County Weed Control
here in Grand Island, Nebraska.
The right of ways that we focus mostly on
are county roadside ditches, bridges,
city utility right of ways including drainage ditches,
and also we do a little bit of railroad right of ways.
We control the right weeds in right of way because of,
first of all, they're noxious weeds.
Some of them are noxious weeds,
or we got general weeds also,
but it's a lot of times for the safety of the public
at intersections, bridges, those types of things
in the city of Grand Island,
help the drainage out in some of the ponds and ditches
and that type of thing.
We spray a lot of brush in the county rights of way.
So that's why we spray some of these...
Right now, some of our methods of treatment are,
we can spray with this roadside truck.
We also spray with the Four Wheeler or UTV, hand sprayers,
or with a handgun, or mechanical methods
such as a chopping or shredding.
Well selection of herbicides depends on the primary
target pests that you're after.
So first thing you need to do is identify your target pest,
whether it be a noxious weed, or an annual weed,
or just a general weed that's causing some trouble.
So you need to identify the pest
whether it's an annual, biennial, perennial,
and whether it's noxious or not.
And then go to specific labels,
see if those weeds are on that label
and select the appropriate herbicide to treat that pest.
In order to prepare ourselves for the proper application
going out to the job site, like I said,
we need to identify the target pest,
so we know what we're going after on that particular job.
Check the weather conditions.
And if we're going out to spray handgun work,
or depending on what situation you're gonna be in,
we need to have the proper PPE,
personal protective equipment, whether it be gloves,
Tyvek suit, boots, that type of thing.
Select the proper PPE for that particular job,
and then go out and make your applications
with the proper herbicide,
and make sure the weather conditions are right,
and go ahead and make the application.
Protection is a big thing depending on what particular job
you're gonna be doing.
Wear the proper PPE for the job.
Also, if it's gonna be a hot day out there,
you gotta protect yourself from the heat,
from the elements, bugs.
Make sure you have your proper bug spray along,
your sunscreen, a lot of liquids
in case it's gonna be a warm day,
but most of the time throughout the day,
we're not gonna be out doing some of those jobs
when it gets to be 90 plus degrees and humidity is too high.
So you gotta watch the heat and humidity
when you're spraying these particular herbicides
so things don't turn on you
and some inversions take place the next morning
or something like that.
So you gotta take your precautions from there.
After application, we come back to the shop,
take our PPE, either dispose of it
or wash the gloves out appropriately,
appropriately wash out the trucks.
Make sure they're cleaned out for the next job
if we're switching chemicals or something like that.
And as far as our clothing,
if we do get it contaminated just a little bit,
we try to remove it right away.
We got some other clothing on hand to change into.
I take my clothes home.
We wash them separately twice from everybody else's.
So we try to take those precautions
and keep everything separate as much as possible.
Some of the different personal protective equipment, PPE,
that can be worn during mixing and loading
maybe versus spraying applications.
During mixing and loading,
you probably are gonna need a face shield,
maybe an apron, long sleeve shirt, Tyvek suit, gloves,
those types of things,
to keep it off your face and off your body.
Whereas if you're out spraying in the roadside
or drainage ditch or something somewhere,
you're probably gonna have on a Tyvek suit or gloves.
And if you're getting down in it,
probably some tall rubber boots, that type of thing.
So some of the equipments are the same,
but there's a few different things that you can wear
while you're mixing and loading also.
Here at Hall County Weed Control,
we try to reduce our exposure to offsite target drift
and that type of thing due to the wind, humidity,
that type of thing.
So in the mornings we check the weather,
see what the wind's doing, the direction of the wind,
so we know what job to go to,
because we need to be aware of other crops
that are around the sites where we're gonna be spraying
and that type of thing.
So we need to be aware of our surroundings
and where we're gonna be spraying on that particular day.
Each morning, before we go out in the morning,
we check our spray system over.
We got different rigs, different pieces of equipment.
So we need to check each one of those out,
depending on which truck we're on.
If it's on a pasture pickup,
we're gonna be checking our pressure on there
and making sure all the nozzles are not plugged,
that type of thing.
If it's on the Four Wheeler or the UTV,
we're gonna be checking the nozzles,
making sure they're not plugged up or anything like that.
And on the Four Wheeler and the UTV,
we can adjust the boom height on that
according to the height of the weeds.
Usually we like to be 20 inches over the top of the weeds
or something like that.
So it just varies.
We can raise and lower that.
Our other trucks aren't quite as...
We can raise the booms on the side,
but the middle one doesn't go up and down.
So we're pretty stationary on that one.
On this particular road truck here,
we have a head with eight different nozzles on it.
And it tips back and forth so we can adjust
our spray pattern on that
and we can shut nozzles on and off.
We can work it from inside the cab.
So this truck works out very nice
in situations where we need to shut some nozzles off
or turn more on.
We just try to keep our equipment up to date and up to par.
So we're putting down the proper rate
when we need to be putting that down.
Here at our office, we use various types of equipment.
We use the Four Wheeler and a UTV.
Those work out real good in small little situations,
small pastures, some of the drainage ditches, ponds,
those types of things.
And then we've got two pasture pickups.
They've got 300 gallon tanks on them, 24-foot-booms.
Those are more of our pasture spraying.
Pickups spray a lot of acres of pasture
every year with those.
So they cover a lot of acres.
We have a roadside spraying pickup truck right here
that we spray a lot of roadsides with,
very adjustable on that.
And we spray what we want, where we want.
We can inject a chemical.
It's got an injection system on it,
so you can inject what you want,
when you want, shut it off.
So it's very versatile on that end.
We also spray a lot with the handguns, just off the trucks,
brush some tall weeds situations in drainage, ditches,
ponds, various things, whatever people want sprayed.
We'll use the backpack or hand sprayers
for just individual cases on roadsides,
say musk thistle or leafy spurge,
Canada thistle, small little things.
We can use the backpacks and hand sprayers.
We'll go into just drive on roadsides,
in the month of June and early July
chop a lot of musk thistles around.
So our equipment and our techniques just vary
in what pest we're after at that particular time.
Our worst weed is probably a musk thistle.
That's the one we have the most acres of.
So we're constantly battling the musk thistle problem
spray a lot of acres of musk thistle.
It's not in severe infestations throughout the county.
They're just scattered.
But we still travel a lot of roadside
chopping a lot of musk thistle and doing that type of thing.
A few of the other weeds
that we do treat a fair amount of are,
leafy spurge, and Canada thistle.
We're finding a few more spots of Canada thistle
all the time.
And so that's creeping up in some crop fields and roadsides
that type of thing.
And we always have to be on the lookout
for purple loosestrife and Phragmites
in some of these wet ditches, wet ponds,
of course, the Platte River,
some of the other creeks around.
We have to always be on the lookout
for phragmites, purple loosestrife.
We wanna be on the early detection,
rapid response mode on that.
Keep it confined to the Platte River.
And we're doing a lot of spraying down there also
with our Platte Valley Weed Management area and things.
But we like to keep it confined to that area.
If we can keep it out of some of these other areas,
that's a great benefit to us,
and the landowners of Hall County.
Well here at the office,
we try to keep our workers as safe as possible
when we're out working on particular roadsides.
We need to have the proper vests on, hazard lights,
strobe lights on top of your trucks, that type of thing,
keep them safe and out of harm's way.
Of course, we got to wear personal protective equipment
while we're spraying also.
But when we're out on a county and state Rights of Way,
we need to have the proper vests on
and let the traffic know that we're out there working.
Well, a couple of the restricted use pesticides
that we do use are Tordon and Grazon.
Situations like that, we need to make sure
that the site is appropriate for those herbicides
to be applied on.
And as far as PPE, we're still gonna do the same thing
that we've always do,
is wear proper gloves and Tyvek if needed.
But most of the time, those are applied through the truck.
So as far as Tordon and Grazon,
it's more of a groundwater issue.
So we gotta be aware of our groundwater situations
in soil types where we're spraying those.
So you have to be aware of what herbicides you're using
and what sites they can be applied on,
and that type of thing.
We surely look for the crops
that are around the particular area,
seeing which way the wind's blowing and that type of thing.
When we're spraying down in the river or around that area,
you need to get a permit, probably checking out
to see if there's any endangered species
in that particular area.
And if you're spraying in the river system,
there are certain dates that you cannot spray
in the river system, anyway.
So you need to be aware of those situations
when you're using those herbicides.
While we're out roadsides spraying,
when we're coming up to a Creek area or a river system,
that type of thing,
we normally shut the spray system off
and do not spray through there.
If there's potential, or noxious weeds,
or general weeds in there that you would like to control,
if you're spraying weeds or spraying herbicides
that are aquatically labeled,
then you would be able to just go ahead
and spray right through that,
and spray in the water and everything.
Before doing that,
making sure your chemicals are aquatically labeled
and that type of thing.
But normally we just spray up to the bridge
or up to the water's edge and stop,
move on and start again after that.
In the beginning of the day,
we figure out where we're gonna go for the day.
We'll go ahead, and we'll back our trucks in,
load up the appropriate chemical
for the site where we're going to that particular day.
So for coming out to spray some roadside,
just general weed control for that day,
tall sunflowers and kochia, that type of thing,
we're gonna be probably just using some 2, 4-D
and a surfactant.
So we'll put in some 2, 4-D into our injection tanks
or into our pickup sprayer and the 300-gallon-tank,
and put in a surfactant in the tank.
And then we'll drive out to our particular site
where we're headed and check the wind out
before we get going,
making sure the wind is out of the right direction
for that day.
It's not blowing towards any sensitive crops.
And then we will begin our application,
whether it be in the roadside truck or handgun situations,
Four wheelers, handguns, hand sprayers, whatever,
we'll make sure we take all precautions
and things we need to do to get started on the job.
Hi, I'm Chris Proctor.
I'm a Weed Management Extension Educator.
Today I'm gonna cover Right of Way weed management,
and just talking a little bit about how to classify
some of the noxious weeds in the state.
When we think about weed control, weed management
in Right of Way situations, or really in any situation,
being able to classify what a weed is and what a weed isn't
And so several definitions are always tossed around
when thinking about weeds.
But certainly a plant out of place
or a plant growing in a place that you don't want,
it would be one way to classify a weed.
Another way to think about it is
anything causing economic loss
or competing with crops or plants that are desirable.
So any kind of competition for light, or nutrients,
water, that would classify that plant as a weed
relative to your desirable plants.
So weeds are classified primarily in two broad categories.
So there's the grass weeds or the monocots.
And then there's the broadleaf weeds
or often called the dicots.
And so those are two broadly distinctive
categories of weeds.
But then also generally,
weeds are also classified by their life cycles.
And so there's three primary life cycles
that we classify plants into and weeds into.
And so there would be annual weeds, biennial weeds,
and then perennial weeds.
And an annual weed is a plant or a weed
that would complete its life cycle in one growing season.
And so that's often distinguished in two distinct...
There's two definitions of annual weeds.
So there could be a winter annual weed.
And so that would be a plant
that would germinate late in the growing season in the fall,
then overwinter and finish its life cycle in spring,
early summer, the next year.
And then there's summer annual weeds.
And those are weeds that would emerge
sometime in the spring.
And by late summer, early fall,
they would complete their life cycle.
A biennial plant, or a biennial weed is a plant
that would complete its lifecycle
over the course of two years.
And so seed would be dropped by the parent plant
late in the season.
That seed would overwinter,
it would germinate in the spring of the next year.
That plant would grow vegetatively,
store up energy, go dormant over the winter time.
And then it would be during that second growing season
that it would reproduce seed
and the life cycles start over again.
And then perennial plants or perennial weeds,
these are any plants that have a life cycle
of two years or more.
So they often reproduced vegetatively if they go dormant
over the winter,
and they have an extended life cycle.
They might produce seed multiple times
over the course of their lifespan.
So in the state of Nebraska,
there's 11 weeds that are classified as noxious weeds.
And so these are weeds that the Department of Agriculture
requires you to control,
or at least prevent from setting seeds.
So either chemically control or cut
to prevent these weeds from reproducing.
So you can see on this slide is listed the 11 weeds
that are classified as noxious weeds
in the state of Nebraska.
And these are weeds that the state would require you
to control if they're found on your land,
either by chemical control or by cutting,
just to prevent them from producing seed.
So just to highlight a couple of the weeds
on the noxious list.
Canada thistle is commonly found noxious weed.
So this is the weed that will grow two to three feet tall.
It's a dioecious plant, which means
there's separate male and female plants.
And it has a pretty extensive underground root system.
And so that makes it challenging to control,
but it also makes timing
particularly of chemical application important
to make sure that the chemicals are controlling the root
and not just the above ground parts.
Another weed to highlight would be common ragweed.
So this is a tall perennial wetland grass.
It ranges anywhere from three to 20 feet in height.
It really prefers a sunny wetland habitat.
So anywhere you have a low line area or a ditch
where you have accumulation of water, wetland-like area,
it would be preferred.
And again, this has an extensive root system
with rhizomes that will get six feet in depth in it.
It can spread pretty pervasively through its root system.
Giant knotweed is another noxious weed in Nebraska.
So this is a perennial that will bloom
anywhere from July to October.
It can grow over 12 feet in height.
It's related to Japanese knotweed,
but it would be distinct.
The leaves are heart-shaped,
often in excess of one foot long.
And another distinct feature of this plant is
it produces allelochemicals from the roots,
and this really helps it out compete
any other vegetation in the area.
So those chemicals would prevent other plants
from successfully growing.
And it can be a challenging plant to manage.
Leafy spurge is another noxious weed in Nebraska.
So this is a member of the spurge family.
And with all plants in the Spurge family,
it has a milky white sap
and the flowers are in parts of threes.
So this produces by seed.
So it produces a lot of seed,
and the seed remains viable in the soil
for up to seven years.
And it can spread vegetatively seven or more feet a year.
So it's a pretty aggressively growing plant.
Salt cedar is another noxious weed in Nebraska.
So this is a perennial shrub or small tree.
It grows five to 20 feet tall.
The stems and leaves of the mature plants secrete salt.
So it's the salt that forms a crust on the soil
and prevents other plants from being able to establish.
And so, again, this is what makes this particular plant
weedy and a challenge to manage.
And it can produce thousands of seeds in any growing season.
So it reproduces rapidly.
The last noxious weed that I'll highlight from the list is
So this is also a plant that favors wetlands.
So this is an herbaceous perennial plant.
It'll produce more than 2,000,000 seeds in a year.
And so, this is one of the mechanisms it uses
to spread rapidly.
It makes it a challenge to manage.
It prefers high temperatures.
And really for it to germinate successfully,
temperatures need to be above 68 degrees.
And it also has a woody root stock.
And so this makes it be able to reproduce vegetatively
each spring as well.
Shown on this slide here is a number of different chemicals
and different herbicides for controlling
both broadleaf and grass noxious weeds
in Right of Way settings.
So, one of the keys to managing weeds
in these Right of Ways,
one is proper weed identification.
So to ensure that you're using the right herbicide
for managing your problem,
identifying that weed is critical.
And the other component that's really important
is understanding the biology of the weeds
that you're controlling.
So the smaller the plant is, when you try to manage it,
the more successful your management will be.
And so being able to understand
when do the plants germinate,
when are they most susceptible
to different management strategies is important.
Hi, I'm Greg Kruger, Cropping System Specialist
at the West Central Research and Extension Center.
And today I'm gonna talk to you
a little bit about pesticide applications
in Right of Ways.
And particularly, we're gonna talk about
making sure that we choose the right nozzles
and making sure that we have the right application setups
to maximize the application and to minimize
unintended effects such as drifting off target movement.
To do that, I think every pertinent conversation
around drift warrants a conversation about wind,
and wind speed, and environmental conditions.
So the first thing we wanna consider is
what are the conditions
that we're making those applications in?
If it's a windy day, maybe pertinent to wait
until conditions are more conducive to applications.
We know that the higher the wind speed,
the greater chance there is for off target movement
or unintended effects to occur.
The second thing we wanna consider when making
applications in Right of Ways is making sure
that we keep the right boom height
if we're using a boom sprayer.
Or if we're using a boomless sprayer,
making sure that that spray pattern is at least
perpendicular to the sprayer,
similar to what a flat boom would be.
We don't wanna have those nozzles pointed up,
and shooting droplets up into the air.
So making sure that pattern or that boom
is level to the ground,
and we've got the droplets heading the direction
we want is absolutely critical.
The closer we can keep that to the ground
yet maintain the pattern, the better off we're gonna be.
We know that the higher that the spray release gets
the more off target movement we're gonna have.
So that would be the second consideration.
Now, the third consideration that we wanna consider is
where sensitive areas may be.
A lot of our labels we work with have setbacks zones
or things like that.
So it's really pertinent
to know the product you're applying,
know what the regulations and the label say
about those products, and make sure that we apply
those products appropriately.
For Right of Way areas,
a lot of the pesticides we may be using
may have setbacks zones around open water bodies
or rivers, ditches, ponds, things like that.
So we wanna make sure that we understand
what the rules are around those products,
make sure we apply them appropriately.
Now the fourth thing that we wanna talk about today,
and the one that we have the most control over,
unfortunately, we can't control
the wind speed and wind direction.
We can't control where those sensitive areas are
other than knowing where they're
and applying products appropriately.
The one thing we do have control over is,
how we set that sprayer up.
And the biggest thing we can do to set up a sprayer
to minimize the off target movement or unintended effects
is to make sure we get the right nozzle selection.
So today I want to show you
just a few different examples of nozzles
that we might consider for Right of Way applications.
This isn't an all-inclusive list,
but certainly these are some analysis
that we consider very good for these types of applications.
Now, the first nozzle I have is a Turbo Flood Nozzle.
It's a TeeJet Nozzle.
This nozzle we're gonna operate between 10 and 40 PSI,
according to manufacturer's recommended operating range.
Now I always encourage guys
to be a little bit higher than 10.
If we get 10 or below, especially if we're using drift,
reducing adjuncts or things like that,
the things that cause that spray solution
to be highly viscous,
we can't lose the spray pattern.
Always like to stay away from that very extreme high-end
for this nozzle that would be 40 PSI,
just because we know that the higher the pressure,
the smaller the droplet size is.
So we wanna make sure that we avoid those small droplets.
'Cause we know those are the ones
that are most prone to off target movement.
Now, this nozzle is a high volume application nozzle.
We're generally gonna see
at least 20 gallon per acre applications with this nozzle.
Not uncommon enough for Right of Way
and other non-crop areas,
just because we wanna make sure that we get good coverage
with the products that we're applying.
Now, the second nozzle I've got is a Turbo Flood Nozzle.
This is also a TeeJet nozzle.
It's gonna have a very similar pressure operating range,
10 to 40 PSI, very similar recommendations.
Personally, I'd like this nozzle a little bit better.
What we tend to see is,
it has a little bit more uniformity
in terms of droplet size.
Also gonna give us
that very close to electric core spray quality.
So we've got really large droplets coming here.
And this nozzle is gonna be good
for those Right of Way applications as well.
Now the third nozzle I've got is a TeeJet nozzle as well.
This one is a little bit unique.
This is what we call boomless nozzle.
And there are several other companies
that manufacture boomless nozzles as well.
They all work in a similar fashion.
They all have slightly different qualities
and characteristics about them,
but they all work in terms of Right of Way applications.
And the fact that this one nozzle here in my hand
can produce a pattern in this up to 18 and a half foot long,
really good when we can't get a boom out
across that open area, over a ditch or over a waterway,
roadside or something like that.
So this nozzle is probably gonna be a good option
for a lot of our Right of Way areas,
just because we don't have to have that boom out there.
We don't take a chance of dropping a boom in the ground
or tearing up equipment.
Now, when using these nozzles, we wanna be real cautious
that these nozzles do have an orientation.
This nozzle I have in my hand,
you can see it has an R marked on it.
That's telling us that this is a right-handed nozzle.
That pattern is gonna shoot out
to the right of the sprayer.
There are left-handed nozzles as well.
Now for many of us making Right of Way applications,
we're gonna be doing that with the flow of traffic.
So this right-hand nozzle is gonna be
more common than the left-handed nozzle.
But if for some reason we were going
opposite of the flow of traffic,
or we were making an application
behind Four wheeler or something,
and we wanted to do broadcast,
we would want that left-handed nozzle as well.
Generally speaking, when we set sprayers up with these,
we would have one of those first two nozzles
that I showed along with this right and left-hand nozzle
for a broadcast application.
One of the first two we showed
would set right in the middle of the sprayer,
or that Four Wheeler, or whatever type of equipment
that we're using.
And then we'd have one of these
oriented out each side of that sprayer.
The last nozzle I've brought with me today.
This is a Hypro Nozzle.
It's called a Hi-Flow nozzle.
Very similar to the first two nozzles that I showed.
The one difference is this nozzle's got
140 degree fan on it.
First two were 110 degree or 120 degree nozzles.
This has got a much wider a pattern on it.
We like this nozzle, much like we like the first two,
because it gives us an altar core spray quality,
getting these really large droplets.
We have a really low drift potential with this nozzle.
If you're working in row crops as well,
you may see either this one or the first two
for applications like fertilizers or things like that,
as well as roadsides in non-crop areas.
The other place that all four of these nozzles may be common
or you may come across this in turf grass situations
where we're making high volume applications as well.
So with that said, the last thing we wanna do
is wrap this up in a consumable piece.
And the take home message is that we wanna be
cognizant of where we're spraying,
what we're spraying, and what the conditions are.
Certainly environmental conditions can change rapidly.
The areas that we're spraying into maybe come unknown.
And whenever that's the case,
it's always pertinent to use good judgment.
When in doubt, shut the sprayer down,
figure out what's around you,
and then come back to making that application.
Make sure that you have the sprayer setup well,
it's calibrated according to whatever intended output
that you have
and make sure that you've done a good job
of setting that sprayer up to make that application.
I'm Rob Schultz from the Hall County Weed Control.
And we're here today to talk about
calibration of spray equipment and why it's important.
And some steps we can go through to calibrate
our equipment properly to get the right amount of pesticide
out on the ground, out on your target.
We're gonna be looking at three different
spray equipment rigs today.
One is a boom sprayer with spray tips on it.
And another is a boomless nozzle spray equipment.
And the next one is pump-up sprayer.
So we'll be looking at these
three different types of spray equipment
and calibrating them.
Now I've changed into my PPE, personal protective equipment
to do some calibration out here
on a piece of spray equipment.
And so some of the tools that you need
to calibrate spray equipment are,
a measuring device, some paint or marking flags,
a spray tip tester, a bucket,
ounce container that measures in ounces, a stopwatch,
a calculator, and even a manufacturer's guide that tells you
a little bit about the tips that you might be using
or tips that may be needed for the output
that you might wanna run.
Because you might wanna run 10 gallons per acre
in some applications, or in other applications,
you might need to run 40 or 50 gallons per acre.
So in that case, just increase in pressure
will not get you that output.
If you need to increase your output that much,
then you need to change spray tips
or go to a bigger boomless nozzle or something on that sort.
Just pressure alone will not increase your output that much.
One of the first things you need to do is figuring speed.
And so the formula that I like to use is,
speed equals distance in feet, times 60,
divided by the time in seconds, time is 88.
And so, I just measure out 88 feet,
and then I calculate in seconds the time it takes me
to go 88 feet.
And that'll figure out your miles per hour on that.
There are many calibration formulas out there to use.
And so the one that I like to use is,
gallons per acre equals, the gallons per minute times 5940
divided by miles per hour,
times the width of your spray operation.
And so first things first.
Like we said before, was figuring out the speed
in miles per hour and the width of your spray booms,
how many inches you're taking in a spray width.
And then we're figuring out the gallons per minute.
And you can plug all those in, and then you know exactly
how many gallons per acre you're doing
with the particular load.
And so you know how many acres you're doing
and then how much product to put in the tank
for the application.
So now we will start up the motor
and we will do some calibration on the tips here,
and do some testing.
At this rate here, it's gonna give you gallons per minute
on this McKinsey spray tip tester.
And so we're gonna be measuring the gallons per minute
on some of these tips to see that.
Now we moved over to our Right of Way application.
Boomless nozzles, there's three different size nozzles
on this particular piece of spray equipment.
And this is a very popular piece of equipment
with these nozzles.
So we'll be calibrating probably the bottom one there.
It's a Boom Buster 110.
And so we still need the bucket
to catch the product and the water.
We're gonna measure it out in ounces.
We're gonna need a stopwatch to calculate it.
I think we should be able to go for about 30 seconds on that
and we need our calculator,
and we will be again using the gallons per acre formula,
but we're gonna figure gallons per minute.
And so, the gallons per acre is the gallons per minute,
times 5940 times, divided by your miles per hour,
times your width.
And so we'll be starting this machine up
and doing a little calibration on it.
Now we have got the spray mixture for the water
in this particular instance for 20 seconds.
And we're measuring it out in fluid ounces,
and it is 64 ounces per 20 seconds.
And so if you take that times three,
you come up with 192 ounces.
And if you divide that by 128,
you come up with 1.5 gallons per minute.
And so that's when we're needing that,
our gallons per acre formula.
And then the other part of our formula is the spray width.
And so we measured that out and we're taking
a 12-foot-spray width there, which is 12 times 12,
is 144 inches.
And you need that in inches
in your gallons per acre formula.
And so gallons per minute figured up to be 1.5.
And so on the bottom side of your formula,
you'd went five miles an hour, which we figured that out
by our speed formula and your 144 inches in width.
And so when we divide that 8910 by 720,
that gives us a 12.37 gallons per acre.
We're putting down with this particular boom.
So we know that this 300-gallon-tank will do 24.25 acres
along the roadside spraying with this particular nozzle.
And so now you know how to do it on the one.
You go back and you do it on the other two nozzles
and continue on calibrating those and get your appropriate
gallons per acre for those particular nozzles.
So the next tool we're gonna calibrate here
is a hand sprayer.
And this can be a backpack sprayer.
This formula can be used for a hand sprayer
off of a truck, many different things it can be used for.
And so one of the first things we're going to do is
measure off an 18 and a half feet
by 18 and a half feet square,
and then we will be spraying that out
and recording our time.
And then we will come back and catch that amount in time
in the ounce container.
And that will tell us gallons per acre,
that we're putting down with our hand sprayer.
So it took me 55 seconds to spray this 18 and a half
by 18 and a half square.
So now we'll catch this water for 55 seconds and see
what we come up with for gallons per acre
out of this hand sprayer.
This methodology works because the test area,
18.5 square feet is 128th of an acre.
A U.S. gallon is 128 fluid ounces.
So the fluid ounces is spray recorded
to test the treat area,
therefore is equivalent to the gallons of spray output
that would be applied to a full acre,
provided the operator, maintains a consistent
pattern of spray output and spray coverage.
So figuring out, we did 24 ounces out of that 55 seconds.
That means I'm putting on 24 gallons per acre.
Then you would know that and go back and figure
how many acres or tenths of an acre
that you're gonna do with this particular hand sprayer.
Then you'll be able to figure out how many ounces
of herbicide or insecticide to put
in this particular hand sprayer.
So in conclusion, here today we have calibrated
these three pieces of equipment to do some spraying with
and in the long run, calibration is very important
just to get the proper amount of herbicide out there
or insecticide, whatever product you might be using.
If you under apply,
you could be creating a resistance in a weed
or something like that.
And if you over apply a herbicide,
you're putting out too many dollars per acre out there.
And so just creating equipment that works properly
and puts out the proper amount of herbicide or insecticide
or whatever product you might be using, is very beneficial.
And so calibration is a great thing to do if not every year,
if not, maybe even two or three times a year,
depending on if you do repairs on your equipment
and that type of thing, new tips, new pumps, various things,
recalibration would be a great thing to do
to make sure you're still putting out
the proper gallons per acre that you would like to put out.
And then you would know exactly how many gallons per acre
you're putting out,
and how many acres that tank fill will do.
So you know exactly how much herbicide, insecticide,
or whatever to put into that tank to get that rate you need
out on the targeted area that you would like to cover.
Hi, I'm Steve Gamet.
And I'm a Viticulture Technologist
for the University of Nebraska Viticulture Program.
And I'm here today to talk to you about spray drift.
Grapes in the state of Nebraska is a $3.4 million industry.
This one particular vineyard has 454 vines to the acre.
And each one of these vines
is worth to the grower $10 a vine.
So this makes this vineyard worth $4,540 to the acre.
To the wine maker, each vine will produce,
say a gallon and a half wine,
or produce seven bottles per vine
making it worth approximately $34,000 to the acre.
So grapes is a very highly profitable crop
and very sensitive to 2, 4-D.
Compare that to a grain crops such as corn,
at 200 bushels at $7 a bushel,
corn would be worth $1,400 to the acre.
That pales comparison just what a grape grower
will get out of his grapes
as opposed to what a corn grower will get out of his corn.
Grapes being a perennial crop
does not need to be replanted year-after-year.
And because it is a broad leaf crop,
the biggest detriment to grape vines is spray drift.
There are two types of spray drifts
that we're concerned about.
One is 2, 4-D and the other is Dicamba.
Both of them being a systemic foliar spray
that enters the vine through the leaves,
and then it can be transferred down to the root system.
They can either kill the plant outright,
or definitely set them back a year or two.
Spray drift is also a concern for organic fruit growers,
vegetable growers, and maybe honeybees.
So spray drift is a big concern
for alternative crop production
here in the state of Nebraska.
So you as an applicator before you wanna spray,
you wanna be sure to check out your surroundings
and get to know your neighbors.
One way of doing that is to check on the DriftWatch website
and check to see who's registered their crop production area
through that site.
Also, you wanna be sure to read the label,
be aware of what the label is telling you,
and how to apply your chemical because the label is the law,
and you're accountable to that law.
Hi, my name is Craig Romary with
the Nebraska Department of Agriculture's Pesticide Program.
And I'm going to be talking a little bit about
DriftWatch and BeeCheck, doing a little bit of review,
introduction of the website for pesticide applicators,
and highlight some of the features
that are available to you as applicators.
DriftWatch and BeeCheck is a communication tool
that displays locations of commercial specialty crops.
And the goal of this is to reduce the incidences
of pesticide drift and crop damage on those specialty crops.
Growers of various commercial crops
register their information and location on the website.
And we're encouraging all outdoor pesticide applicators,
and that would be private applicators,
commercial applicators, including ornamental and turf,
Right of Way, public health vector control,
any type of outdoor applicator to use the service,
become familiar with the website
and adjust your applications as needed
when you're near these sites.
So the jumping off point to get to DriftWatch and BeeCheck
is the website, and that's fieldwatch.com.
And this is the non-profit company
that maintains the services.
And you'll see on this website, some various buttons here
for going different places.
This one here is for the specialty crop producers
to go to and register their crops.
This is for beekeepers.
This is the BeeCheck registration.
And then this is the FieldWatch.
They're calling this FieldWatch for Applicators.
So I'll go through the map,
show you a little bit about the features
and then give you some ideas
of why this might be useful to you,
and how you might use it.
So you go to FieldWatch for Applicators.
And if you just wanna go to the map
to see what's near your area,
you would go up here to the top and click FieldWatch map.
Once you do that, you see the states that are in the system.
Right now, I think there's 14 and one Canadian province.
They are working to get more all the time.
So you can click on Nebraska,
and it'll bring up all of the sites.
This is the first easiest way for you as an applicator
to utilize this service.
You can see the sites available, the crop types,
and you can zoom in as far as you need to, go in.
Wherever you need to, you can search at the top
by town, address, or zip code,
or you can just use the map functions
and then click on a site.
If that's in your area, see what they have.
This person raises potatoes.
You can give them a call
or send them an email if you would like.
We're also encouraging that,
just to continue the communication
between pesticide applicators and the growers.
Here's a vineyard.
Again, just a way to open up communication.
If you see something that's incorrect
about this particular site,
you can send me an email and let me know
what it is that you found wrong.
So this is the first way to see
what's available on the website.
And this is free to use.
Anybody can publicly access the map.
However, you may not see all of the beekeeper sites
because the beekeepers have the option
to only make this available to applicators
who have actually registered within FieldWatch.
And that's just a feature that they've given to beekeepers
to prevent the potential for hive theft,
if that's a concern to them.
So using the map, you would go to this step if you want to.
The next way to utilize the map would be
to go back to the registration part.
And here you would register as an applicator.
Go to the FieldWatch for applicator's part.
And if you haven't registered,
you would enter in this information.
And the advantage of this is that part of this process,
you actually select an area,
whether that's a number of counties,
or whether you actually draw an area of interest,
or a business area on the map.
And the advantage is,
whenever somebody new adds information into that area,
you would get an email letting you know
that something new has been added.
And then actually within that email,
you could click, and it would take you to that site.
And that is also free.
And again, if you're interested in bees,
you would be able to see all of the beehive sites
in that area by registering and taking advantage of this.
And then the last option for applicators,
FieldWatch is also offering data feeds and data downloads
to people who wanna pay the minimal fee,
which is I think $100 a year.
A membership fee which helps them pay for their service.
And you can get that information fed directly
to your computer at the office,
or actually in the machine that you're operating.
And so that may be an option of interest for people,
for businesses, or other types of individuals
who may make lots of applications
and have a wider area of interest.
So I would encourage you to take a minute
to go to the FieldWatch website,
become familiar with the services there,
become familiar with the BeeCheck, DriftWatch map,
and incorporate that into your spray operations.
Become familiar with the locations in your area.
And also just encourage you to consult
the education material that is likely in your packet today
on spray applications,
become aware of the potential for drift.
And then certainly if you have any questions,
feel free to give me a call at 402 471 6883.
Hi, I'm Libby Smith with
the Nebraska Department of Agriculture's Pesticide Program.
And today I'm here to speak to you
about a couple of the rules and regulations
you might come across
while making Right of Way applications.
First off, what is a restricted use pesticide?
The EPA classifies restricted use as a pesticide
that might cause an unreasonable adverse effect
on human health and or the environment.
Some active ingredients may fall under both restricted use
and general use depending on their formulations,
application methods and intended use.
Restricted use products or RUPs
are only sold to certified applicators,
and may only be applied to certified applicators.
The restricted use statement will be posted on the label
and indicates the specific hazard of each pesticide.
To purchase restricted use products, you must hold
a valid commercial or non-commercial applicator's license.
A commercial license is required
by those doing applications for hire,
while a non-commercial license is for applicators,
who will be applying their pesticides directly to land
or property owned by their employer.
And an example of this would be
a Department of Roads employee.
How to acquire such a license.
To obtain a pesticide applicator license,
both commercial and non,
you must demonstrate practical knowledge
of the principles and practices of pest control
through examination and or training.
To become initially certified, you must pass two exams,
a general and a category exam
with a passing score of 70% or higher.
You can take these exams as many times as you'd like,
and we will keep the passing records on record
for over a year.
If you do not pass one exam,
you will receive a pass/fail letter.
And if you pass both,
we will notify you of your passing score with a postcard.
Here's an example of what
a commercial pesticide applicator postcard looks like.
This will have instructions to go online
and purchase the license.
Our exams are offered through three different avenues.
One is by attending initial training course
offered through UNL.
These courses are usually offered
in the early spring and late winter.
And they include training videos and demonstrations
before taking the exams.
The second option is a testing only option.
This will be administered by an NDA staff member
at many of the county extensions.
A third option is through Pearson VUE,
a third-party testing service.
Next, we will talk about the 60-Day Rule.
The 60-Day Rule is a once in a lifetime
license exemption offered to those
who have never held an applicator's license before.
This license exemption is designed to allow new employees
to work under the supervision of an employer
who is currently certified while obtaining their license.
The two basic requirements of the 60-Day Rule
is that the non-certified applicator works directly under
the certified applicator in the corresponding categories,
and that the certified applicator assumes all responsibility
of the non-certified applicator.
Any person who is applying for a 60-Day Exemption
must submit an application to NDA
within 10 days of their first application.
Applicators should read the pesticide label
before purchasing, and again,
to make sure you're mixing, loading,
and disposing pesticides correctly.
It is the applicator's responsibility to read,
understand, and follow the label directions.
The label is the law.
Elements of the product label.
The product label is the direct communication
between manufacturers and the applicator.
It is a legal document.
The product label will contain trade name, brand name,
product name, ingredient statement, the chemical name,
the use classification statement, the type of pesticide,
the net contents, address, and name of manufacturer,
telephone number, the EPA registration number,
establishment numbers, signal words,
any precautionary statements, environmental hazards,
or chemical hazards, the agricultural use requirements,
non-agricultural use requirements,
storage and disposal, and use directions.
The best legal method for disposal is to apply the pesticide
to a site approved on the label.
Rinse water is considered a waste pesticide,
and should be collected and applied to an approved site.
Non-refillable containers should be triple rinsed
and offered for recycling at an approved landfill.
Clearly mark and puncture triple rinsed containers.
UNL offers a list of sites that are approved
for pesticide container recycling at pested.unl.edu.
Records are required to be kept for all applications
of restricted use pesticides.
These records must be completed within 48 hours
and are to be kept for a minimum of three years.
Records should also be stored
at the principal place of business.
Thank you, and remember to apply pesticides safely.
We've learned a lot of valuable information today.
We hope that this information helps you make
informed identification of vegetation,
proper control, and proper application,
and to consider herbicide-sensitive sites while applying.
