What area is being treated?
- Will you apply the pesticide to more than 50% of the field?
- Or will you
treat less than 50% of the field, by using strip applications or
spot sprays, for instance?
How much pesticide will come in contact with the soil?
- Surface applied means that you will apply the pesticide to bare ground
or an incomplete canopy.
- Foliar applied means that you will apply the pesticide when the crop
or weeds are at nearly full canopy.
- Soil incorporated means that you will incorporate the pesticide
into the soil.
What is the application rate?
- Rates above 1/4 pound of active ingredient per acre are considered
the "standard" rate
- Rates from 1/10 to 1/4 pound active ingredient per acre are considered
to be low by WIN-PST.
- Rates less than 1/10 pound of active ingredient per acre are considered
to be ultra low by WIN-PST.
- If you don’t know the percent active ingredient for a product,
to use to calculate pounds of active ingredient, you can look up the
product in an online database.
