What does transformation refer to regarding pesticides?

Transformation regarding pesticides refers to the conversion of a pesticide into a different substance. This process can occur through various mechanisms such as chemical reactions, degradation, or metabolic processes. When a pesticide transforms, it may change its chemical structure, potentially altering its effectiveness, toxicity, and environmental impact. Understanding transformation is crucial for assessing how long a pesticide remains active in the environment and how it might affect non-target organisms.

The other concepts mentioned, such as movement across large areas, application processes, and the development of new products, do not capture the specific meaning of transformation in the context of pesticide chemistry and environmental science. Each of those aspects plays an important role in pesticide use and regulation, but they focus on different processes and implications associated with pesticide application and lifecycle.
