Quiz Pesticides, the Environment and IPM

The airborne movement of pesticide particles from the target area occurs only during application and is clearly visible when it occurs.     True or False

Pesticide adsorption is greatest in course, sandy soil.          True or False

Runoff is usually more likely from a water-saturated soil than from an unsaturated soil.     True or False

Pesticide properties have little if any effect on whether a chemical will reach groundwater.     True or False

Drift can be minimized if precautionary measures are taken (monitor weather, alter spray systems).         True or False

Drift is most commonly due to off-target movement of pesticide spray droplets.          True or False

Three primary factors contribute to pesticide spray drift:
I. Weather conditions
2. Equipment configuration and operation
3. Applicator attitude
True or False

The first step in any IPM program is thorough inspection. There are several reasons for inspecting the premises including, giving the client a good show.   True or False

Drift can be defined simply as the movement of a pesticide through the air to a non-target area. There are two types of drift: Particle Drift and Vapor Drift.    True or False

Particle Drift refers to small spray droplets carried by air movement from the target area during application.    True or False

Spraying when it is convenient and disregarding existing weather conditions will often result in off-target pesticide application leading to inconsistent pest control and possible damage to adjacent crops or properties.     True or False

No other non-chemical control measure can have a more beneficial effect than sanitation.         True or False

Vapor Drift refers to the movement of pesticide vapors from the target area.     True or False

Application of a volatile pesticide should be avoided when conditions favor volatilization, such as high temperatures combined with low humidity.             True or False

Wind speed is the major weather condition affecting drift. The greater the wind speed, the greater the drift.      True or False

As the droplet size increases, the potential for drip decreases.       True or False

Physical properties of liquids – The viscosity of a liquid is a measure of its resistance to flow. For example, mayonnaise is less viscous than water.                True or False

The amount and persistence of pesticide adsorption varies with pesticide properties, soil moisture content, soil pH and soil texture.      True or False

In general, dusts are more hazardous to bees than sprays; wettable powders are more hazardous to bees than either emulsifiable concentrates or water-soluble formulations.        True or False

Pesticides can enter water via drift, surface runoff, soil erosion, leaching, and in some cases, deliberate or careless release of the pesticide directly into the water. Fish kills are most often caused by insecticide contamination of small ponds or streams with low water volume or turnover.     True or False
