What factor can influence the effectiveness of a pesticide application?

Weather conditions, such as wind and rain, play a significant role in the effectiveness of a pesticide application. Wind can cause the pesticide to drift away from the target area, leading to insufficient coverage on the intended pests or plants. If the wind is too strong, it can disperse the pesticide particles into non-target areas, potentially causing harm to beneficial organisms or surrounding plants.

Rain is another critical factor; if it occurs shortly after application, it can wash away the pesticide before it has had a chance to adhere to or penetrate the target organisms, nullifying its intended effects. Therefore, understanding and monitoring the weather conditions prior to pesticide application is crucial for achieving optimal results.
