ILLINOIS PESTICIDE APPLICATOR TEST
COMPLETE TEST PAPER WITH CORRECT
ANSWERS
◉ Vapor drift.
Answer: Formed after application, carried out of the target area
(volatilization), can occur up to several days after. Some products if
used in hot weather.
◉ Factors increase drift.
Answer: Droplet size under 200 microns, wind/air currents, sprayer
too far from plant, high temps with high evaporation.
◉ Movement of pesticides by water.
Answer: Leaching, seepage, application prior to rainfall, runoff into
surface water.
◉ Reducing movement of pesticides by water.
Answer: Nozzle pressure, droplet size, spray height.
◉ Leaching.
, Answer: Movement of pesticide downward in soil profile with
percolating water. Can contaminate groundwater.
◉ Pesticides degradation in groundwater.
Answer: Is much slower in groundwater because of low oxygen and
light.
◉ Leaching more likely if.
Answer: Pesticide over-applied, sandy soil, soil is bare, pesticide
properties, applied before heavy rain/irrigation, spills.
◉ AI.
Answer: Active ingredient - chemical effective against pest.
◉ Inert ingredients.
Answer: Don't harm pest but make the AI more effective.
◉ Herbicide formulation.
Answer: May be ready to use or may require dilution with carrier
(oil or liquid).
◉ 60WDG.
Answer: 60% AI water-dispersible granule.
