Toxicity of pesticides is important for farmers to understand because it can affect your health and safety. It also helps when addressing questions that come from consumers about why you use pesticides and how toxicity compares to products they use every day. When considering the toxicity of pesticides, we need to address the toxicity to both pests and humans. But first, please note the term pesticide refers any chemical used to manage pests (insecticide, herbicide, fungicide, etc), and a pest refers to what is being controlled (insect, weed, disease, etc).
