What effect does high temperature have on pesticide applications?

High temperatures can significantly affect pesticide applications by creating hazardous conditions for both the applicator and the plants. Elevated temperatures can lead to increased volatility of certain pesticides, causing them to evaporate more quickly and potentially drift away from the target area. This drift can not only reduce the effectiveness of the pesticide but can also expose non-target plants and nearby ecosystems to unintended chemical exposure, potentially causing harm. Additionally, high temperatures can stress plants and make them more susceptible to damage from the applied chemicals, resulting in phytotoxicity, where the plants exhibit negative reactions. Therefore, understanding and considering the implications of high temperatures during pesticide application is critical for safety and effectiveness.
