Temperature plays a significant role in the efficacy of pesticides because it influences both the chemical processes and the biological activities involved in pest control. At higher temperatures, the rate of evaporation can increase, which may lead to quicker degradation of certain pesticide formulations, reducing their effectiveness. Additionally, temperature can affect the metabolism of pests; for instance, warm conditions can enhance pest activity, possibly requiring more frequent application or adjustments in dosage to achieve desired control.

Moreover, temperature affects the solubility and viscosity of pesticides, which can influence how well they disperse and penetrate pest populations or the plants they are intended to protect. Optimal temperatures can promote effective absorption and interaction of the pesticide with target organisms, while extreme conditions could either hinder or enhance toxicity levels.

In comparison, while soil nutrients can influence plant health and potentially affect pest populations, and humidity levels can affect the stability and efficacy of certain formulations, their impacts are not as direct or pronounced as temperature. Crop variety might influence resistance to pests but does not inherently affect the pesticide’s action or effectiveness in the same immediate manner as temperature.
