Department of Agriculture 6. Pesticides in the Environment

What are the two types of drift?
-Runoff and Erosion
-Vapor and Particle
-Driftless and Driftmore

Who is responsible for drift? 
-The land owner
-The chemical manufacturer
-The applicator

What steps may be taken to avoid/prevent vapor drift?
-Incorporate the pesticide into the soil as directed
-Use amine formulations rather than ester formulations
-Avoid applications during hot weather 
-All of the above

Describe two ways pesticides can move off the treated area into nearby surface water.
-Vapor and Particle
-Driftmore and Driftless
-Runoff and Erosion

To prevent surface-water contamination, don't spray before ___ rain.
-light 
-heavy

True or False? Contaminated groundwater is long lasting due to a lack of oxygen and sunlight.
True False

True or False? It is extremely expensive if even possible to purify contaminated groundwater.
True False

True or False? Leaching is less likely to occur in sandy soils that are low in organic matter.
True False

How is pesticide persistence measured?
-Degrees
-Feet/Second
-Half-life

A pesticide is applied at a 2 lb/A. Its half-life is 20 days. How many lbs/A are left after 20 days?
-1
-2
-20

True or False? Leaching is more likely to occur with these pesticides:
-Highly persistent
-Poorly adsorbed to soil
-Highly water soluble
True False

The greatest threat to groundwater is the ___ of pesticides.

-Runoff

The 4 factors that affect leaching are pesticide properties, soil properties, ___ conditions and management practices.
-site 
-sink
-source

Shallow aquifiers are ___ susceptible to leaching.
-more
-less

For major spills, who are you required to contact?
-Illinois Emergency Management Agency (IEMA)
-Ghostbusters

True or False? If you have a pesticide spill from a hose rupture, you should first call the proper authorities and then shut off the pump on your sprayer.
