The grouping method that refers to how a pesticide interacts with pests is based on its effect on those pests. This classification emphasizes the biological and chemical mechanisms by which the pesticide disrupts pest life processes, such as growth, reproduction, or survival. Understanding the effect on the pest is crucial for selecting the appropriate pesticide for a specific pest problem, as different pesticides might target different physiological pathways or life stages of the pest.

For example, some pesticides may act as neurotoxins, disrupting the nervous system of insects, while others might inhibit metabolic processes or development. Knowing how a pesticide affects a pest can lead to more effective pest management strategies, as it allows for targeted use that minimizes impact on non-target organisms and the environment.

The other grouping methods, while relevant in their own contexts, do not specifically address the interaction between pesticides and pests. Environmental impact focuses on how pesticides affect ecosystems, inherent properties relate to the chemical structure and characteristics of the pesticide, and method of application pertains to how the pesticide is delivered, rather than the specific way it impacts the pest itself.
