1. What happens to a pesticide after it is applied?
Answer: A pesticide can either be absorbed, break down (transform), or move off-site (transport) after
application.
2. What is transportation in relation to pesticides?
Answer: Transportation refers to the movement of pesticides away from their intended site of action,
such as through leaching and runoff.
3. What factors influence a pesticide's ability to contaminate water?
Answer: Factors include solubility, adsorption, persistence, and transformation.
4. What is runoff, and under what conditions is it more likely to occur?
Answer: Runoff occurs when the precipitation rate exceeds the rate of water infiltration into the soil or
when it lands on a hard surface. Conditions that increase the likelihood of runoff include misapplication
onto hard surfaces, rain too soon after application, and over-application.
5. What is leaching, and how does solubility impact it?
Answer: Leaching refers to the downward movement of pesticides through soil, and solubility plays a
significant role in this process.
6. What is volatilization, and what environmental factors contribute to it?
Answer: Volatilization occurs when a pesticide changes from a solid or liquid to a gaseous phase.
Environmental factors such as wind, rain, temperature, and humidity can contribute to volatilization.
, 7. What are some potential environmental impacts from pesticide use?
Answer: Potential environmental impacts include surface water contamination, groundwater
contamination, and impacts on non-target plants and animals.
8. How can you reduce environmental impacts from pesticide applications?
Answer: Strategies for reducing environmental impacts include using integrated pest management (IPM)
to choose the least toxic but effective product, applying pesticides carefully, following label directions,
cleaning up spills, paying attention to site and weather conditions.
9. What is glyphosate, and what is its common use?
Answer: Glyphosate is the active ingredient in Roundup, a synthetic herbicide used to control broadleaf
weeds.
10. How do weather conditions impact pesticide use?
Answer: Weather conditions such as wind (drift of pesticides), rain (rain too soon after application), and
temperature and humidity (resulting in volatilization) can all impact pesticide use.
11. What is dicamba, and what is its common use?
Answer: Dicamba is a synthetic auxin herbicide used to control broadleaf weeds.
12. What are some characteristics of turfgrass?
Answer: Turfgrass is less likely to result in runoff due to its natural absorption capacity and requires
regular input to stay healthy.
