Chemicals specifically used to control weeds are known as what?

Chemicals that are specifically formulated to control weeds are known as herbicides. This classification of chemicals targets unwanted plants, effectively inhibiting their growth or destroying them altogether. Herbicides function by disrupting the processes essential for the survival and reproduction of these plants, thus helping to manage weed populations in various environments, from agricultural fields to home gardens.

Pesticides is a broader category that encompasses all substances used to control pests, which includes insects, weeds, and diseases. Insecticides are specifically aimed at controlling insect pests, while fungicides are designed to combat fungal infections in plants. Since the question specifically asks about chemicals for controlling weeds, herbicides are the precise answer, highlighting their distinct role in weed management. Understanding these definitions helps clarify the specific functions of these chemicals in pest management strategies.
