What type of agricultural chemical is used to control fungal diseases?

Fungicides are specifically designed to inhibit the growth of fungi or to kill fungal spores. They are commonly used in agriculture to protect crops from diseases caused by fungi, such as mildews, rusts, and molds. The mode of action of fungicides may involve disrupting the cellular processes of fungi or inhibiting their ability to reproduce, thereby reducing the infection and spread of the disease.

In the context of the other options, herbicides are used to control weeds, which are unwanted plants; insecticides target insects that may harm crops; and rodenticides are meant to eliminate rodent populations that can cause damage to agricultural products. Each of these types of chemicals serves a unique purpose and is formulated to address specific pests, making fungicides distinct and essential for managing fungal diseases in agriculture.
