[00:00:00.948]Okay, so there’s a couple of common
[00:00:03.008]formulations out there that you’re
[00:00:05.008]going to run into.
[00:00:06.178]Generally speaking, that would be
[00:00:08.148]a liquid or a dry type of formulation
[00:00:10.248]or a solid. Typically the liquids
[00:00:12.598]are diluted in water to make
[00:00:14.308]a finished spray but they could also
[00:00:16.368]include other solvents like crop oil
[00:00:18.358]or another light oil as a carrier
[00:00:20.198]rather than the water.
[00:00:21.808]Dried formulations are usually
[00:00:23.648]ready to use as a dust, or they’re
[00:00:25.978]mixed with water prior to application.
[00:00:31.501]As I said, the dry can come in a lot of
[00:00:33.841]different formulations - dusts that
[00:00:36.441]you might apply to a garden is
[00:00:38.611]a good example of that formulation.
[00:00:42.611]Baits are common as dry formulations.
[00:00:45.341]Granules are another one we often see.
[00:00:48.161]It’s a convenient way for delivering
[00:00:51.511]a product. We can get it out there easily
[00:00:53.871]and safely with granules,
[00:00:55.671]and the granules will then in turn
[00:00:57.801]break down and do their activity
[00:01:00.201]that way. Pellets are real common
[00:01:02.861]in rodenticide baits. They’re pressed
[00:01:05.431]into pellet shapes –
[00:01:07.461]that’s another dry formulation.
[00:01:09.641]And then, as we’ve mentioned
[00:01:11.641]several times before, wettable powders,
[00:01:14.051]which are first diluted in water
[00:01:16.151]before use.
[00:01:18.251]Liquids – you’ve got things
[00:01:20.531]like ECs or emulsifiable concentrates
[00:01:22.931]that require special formulations
[00:01:25.111]in order so that they will mix with water.
[00:01:27.451]You have solutions,
[00:01:29.841]ultra low volumes or ULVs,
[00:01:31.951]flowables – are all examples
[00:01:33.941]of semi-liquids that are added to water
[00:01:37.451]in order to be more easily applied.
[00:01:41.451]Then, aerosols are pressurized
[00:01:43.291]in containers like plastic or metal,
[00:01:46.391]typically is how aerosols are delivered.
[00:01:51.071]And then RTUs or ready-to-use products
[00:01:53.671]are another type of liquid formulation
[00:01:56.155]that we’ll run into.
[00:01:58.825]And then a totally different one
[00:02:00.795]are the fumigants.
[00:02:01.995]Fumigants are dispersed as a gas or vapor.
[00:02:05.165]Examples of that would be methyl bromide,
[00:02:08.115]aluminum phosphide, magnesium phosphide,
[00:02:11.395]as well as rodent smoke bombs.
[00:02:14.085]Those are all examples
[00:02:15.615]of fumigant-type formulations.
[00:02:18.425]So, you’ll see that there is a number
[00:02:20.545]of advantages and disadvantages to any
[00:02:23.255]formulation that you might choose.
[00:02:25.615]Just one example is the emulsifiable
[00:02:27.825]concentrate, where it has an advantage
[00:02:30.605]of relative ease to handle, transport, and
[00:02:33.025]store; easy to measure and pour.
[00:02:37.025]A disadvantage is that they are readily
[00:02:40.185]absorbed into skin, and the solvents
[00:02:42.375]can sometimes cause damage to equipment,
[00:02:46.115]and, additionally, wear and tear.
[00:02:48.405]So, that’s just one example of advantages
[00:02:50.820]and disadvantages.
