Windy conditions can significantly impact pesticide application for several reasons. When applying pesticides, wind can cause drift, meaning that the pesticide may be carried away from the target area by the wind. This can lead to ineffective pest control, as the product doesn't reach the intended pests, but more importantly, it can also pose risks to non-target areas, including nearby crops, gardens, and even human populations. Additionally, drift can result in contamination of water sources and harm beneficial organisms in the area, which is why fine-tuning the timing and conditions of pesticide application is essential for efficacy and safety.

In contrast, sunny and clear weather, high humidity, and cool temperatures typically have less immediate negative impacts on pesticide application, although they may have other effects on plant uptake and evaporation. Cloudy or humid weather may even be beneficial in some cases since higher humidity can help reduce volatility and evaporation of certain pesticide formulations, although extreme humidity may still cause issues with application equipment.
