What is the consequence of using pesticides during wet conditions?

Using pesticides during wet conditions can lead to a higher risk of runoff. When the ground is saturated or wet, applied pesticides can easily wash away into nearby water bodies or non-target areas instead of being absorbed by the plants or soil they are intended to protect. This runoff can lead to environmental issues, such as water contamination, and can also reduce the overall effectiveness of the pesticide application as it may not reach the target pests or plants as intended.

Other choices do not accurately reflect the impacts of applying pesticides in wet conditions. Better efficacy suggests that the pesticides would work more effectively, which is not true due to the risk of dilution and loss through runoff. Increased task efficiency implies that the application would require less time or labor, which is often not the case in wet conditions since the application may need to be done more cautiously or may even need to be delayed. Lower effectiveness could imply that the pesticide is less effective overall, rather than focusing on the specific harmful impact of runoff potential when applied inappropriately during wet conditions.
