Why might high temperatures negatively affect aerial pesticide applications?

High temperatures can significantly impact aerial pesticide applications primarily because they increase the evaporation rate of pesticides. When temperatures rise, the volatility of the chemical compounds in pesticides also tends to increase, leading to a quicker evaporation of the active ingredients. This rapid evaporation can reduce the effectiveness of the pesticide, as less of the product remains available to adhere to the targeted pests or plants.

Additionally, high evaporation rates can contribute to drift, which is when pesticide particles become airborne and move away from the intended application area. This drift can lead to unintended exposure of non-target organisms and environments, reducing overall effectiveness and posing ecological risks. By understanding the relationship between high temperatures and pesticide behavior, applicators can make more informed decisions to optimize their application strategies and minimize potential issues.
