Which environmental conditions accelerate pesticide degradation?

The correct choice is warm and wet as these conditions significantly enhance the processes that lead to pesticide degradation. Higher temperatures generally increase the rate of chemical reactions, including those that break down pesticides. Additionally, when the environment has high humidity or moisture levels, it can promote microbial activity and enhance hydrolysis — two key processes that contribute to the breakdown of pesticides.

In moist conditions, microorganisms that decompose organic materials can thrive, leading to a faster degradation of pesticides as they are metabolized by these organisms. The combination of warmth and moisture creates an ideal environment for biological processes that reduce the persistence of pesticides in the environment, thereby accelerating their degradation.
