Pesticide Certification Ch. 6

Which statement is true about protecting bees from pesticide injury?

• wettable powders are the safest formulation for preventing bee injury

• it is best to spray crops when they are in bloom

• aerial applications are less hazardous to bees than ground applications

• applying pesticides in the evening or during early morning is recommended

what label statement will be on pesticides that might harm endangered species?

• advice to consult a county bulletin to determine what special precautions to take when using the product

• advice to consult a local conservation officer for a permit to apply the pesticide

• ban on use of the pesticide in all areas where endangered species might be harmed

• a list of the endangered species that might be harmed by the pesticide

which of these soil types is most likely to experience leaching?

• heavy clay soil, low in organic matter, where groundwater is shallow

• heavy clay soil, high in organic matter, where groundwater is deep

• sandy soil, high in organic matter, where groundwater is deep

• sandy soil, low in organic matter, where groundwater is shallow

Which of these may be a cause of non-point source pollution?

• back-siphoning of pesticide spills at a wellhead

• leaching from a pesticide mixing area

• pesticides that dissolve and leach through the soil after a rainfall

• dumping leftover pesticide products down a well

What characteristic of a pesticide makes it likely to move with water in surface runoff?

• high solubility

• high adsorption

• high volatility

• a tendency to evaporate quickly

What two factors are most important in reducing spray drift?

• droplet size and wind condition

• temperature and wind condition

• viscosity of liquid pesticides and air turbulence

• temperature and pesticide volatility

What two factors are most important in relation to vapor drift?

• droplet size and wind direction and speed

• air stability and temperature

• viscosity or liquid pesticides and air turbulence

• temperature and pesticide volatility

Which statement about sensitive areas is true?

• Never spray a sensitive area to control a pest for any reason.

• Do not spray a larger target site if it contains a sensitive area.

• Pesticide labels may contain statements that list special precautions around sensitive areas.

• Endangered species habitats are not considered sensitive areas.

Which is a recommended best management practice for preventing contamination of surface and groundwater by pesticides?

• Use pesticides that are highly water soluble

• Use terrace and conservation tillage practices.

• Clean sprayers near sinkholes.

• Select persistent pesticides.

Which statement is true about groundwater or surface water contamination by pesticides?

• Pesticides cannot reach groundwater by runoff

• Runoff and erosion are sources of surface water contamination by pesticides

• Pesticide-contaminated surface water will not reach groundwater

• Groundwater or surface water contamination risk is low when a heavy rain immediately follows a herbicide application
