What is the influence of humidity and temperature on pesticide application?

Humidity and temperature play a significant role in the evaporation of water from pesticides, which is critical for effective application. When the temperature is high and humidity is low, water tends to evaporate quickly, which can affect the pesticide's concentration and efficacy. Rapid evaporation may lead to a situation where the active ingredients do not remain long enough on the target surface to be effective, potentially reducing the overall effectiveness of the treatment.

Similarly, high humidity can slow down evaporation, allowing pesticides to remain active on the plants or surfaces longer, which can enhance their effectiveness. Understanding these dynamics helps applicators to time their applications better and adjust their techniques to optimize pesticide performance.

Thus, recognizing how humidity and temperature influence evaporation is essential for applying pesticides efficiently and effectively.
