Which practice can contribute to pesticide drift?

The practice related to pesticide drift is primarily influenced by the timing of application, which is why the choice of application timing is significant. When pesticides are applied at inappropriate times, such as during windy conditions or when temperatures are high, there is a greater chance for drift to occur.

For instance, applying pesticides during high temperatures may cause the spray to evaporate more quickly, and a light breeze can carry these airborne particles to unintended areas. Selecting the right time, such as periods of lower wind speed, can greatly reduce the risk of drift, ensuring that the pesticides reach their intended targets instead of affecting nearby crops, wildlife, or water sources.

The other practices listed, such as using low-pressure sprayers and spraying during calm weather, can help manage drift but are not as directly impactful as the decisions made regarding when to apply pesticides. Wearing proper safety gear, while essential for the safety of the applicator, does not influence the behavior of the pesticides in the environment.
