Wisconsin Pesticide Applicator Training (PAT) Right-of-Way & Natural Areas Practice Exam

"Mode of action" in the context of pesticides specifically refers to the method by which a pesticide works to harm or control a pest. This encompasses the biochemical and physiological processes that the pesticide affects once it is absorbed by the pest. Understanding the mode of action is crucial for effective pest management, as it helps in selecting appropriate products based on the pests being targeted, minimizing the likelihood of resistance development, and ensuring safety to non-target organisms.

For instance, a pesticide might inhibit a pest's nervous system or disrupt its growth and development. This understanding enables applicators to make informed choices about how and when to apply the pesticide for maximum effectiveness. Knowing the mode of action is also valuable for rotating different products to manage resistance, as using products with different modes of action reduces the risk of pests becoming resistant to a treatment.
