Agricultural chemicals that control pests are collectively referred to as what?

The term that encompasses all agricultural chemicals used to control pests, including weeds, insects, fungi, and other unwanted organisms, is "pesticides." Pesticides serve as a broad category that includes several subcategories, such as insecticides (which specifically target insects), herbicides (designed to kill or inhibit the growth of weeds), and fungicides (which are effective against fungal diseases). This overarching classification is essential for understanding the various functions and applications of these chemicals in agriculture. By using the term pesticides, one can recognize that it includes all forms of pest control chemicals, making it the most accurate choice in this context.
