Herbicides are specifically designed to control and eliminate weeds, which are unwanted plants that compete with desirable crops or vegetation for resources like nutrients, water, and light. They work by targeting the physiological processes unique to plants, often disrupting growth, photosynthesis, or nutrient uptake. This targeted action allows herbicides to effectively manage weed populations while minimizing harm to other plants, when used as directed.

Fungicides, on the other hand, are created to combat fungal infections in plants, aiming to prevent or control diseases caused by fungi. Insecticides target pests such as insects, helping to manage populations that can damage crops. Rodenticides are formulated to control rodent populations, which can cause significant damage to agricultural products or stored food but are not effective against weeds. Each type of pesticide has a specific role in agricultural management and environmental protection, highlighting the importance of using the appropriate product for the desired outcome.
