In agricultural terminology, what does 'pesticide' encompass?

The term 'pesticide' is a broad category that includes any substance used for preventing, destroying, repelling, or mitigating pests. This definition encompasses a variety of agricultural chemicals, including insecticides (which target insects), herbicides (which control weeds), fungicides (which manage fungal infections), and many others that may deal with different types of pests.

Choosing the option that states pesticides include all types of agricultural chemicals reflects the comprehensive nature of pesticides in managing both crops and livestock by targeting multiple forms of agricultural nuisances. This understanding is critical for anyone studying agricultural practices, as it highlights the importance of these chemicals in ensuring healthy and productive farming.
