Which chemical is used for weed control?

Herbicides are chemicals specifically designed to control unwanted plants, commonly known as weeds. They work by targeting specific physiological processes in plants, either by inhibiting growth or by causing the plants to die. This makes herbicides a crucial tool in agriculture and gardening for maintaining crop health and maximizing yield by reducing competition from weeds.

Fungicides, while also used in agriculture, target fungal pathogens and are not effective against weeds. Insecticides are meant to control insect pests, which have different biological targets compared to weeds. Nematicides are used to manage nematodes, a type of microscopic roundworm, and do not address weed problems. Each of these chemicals plays a unique role in pest control, with herbicides being the correct choice for weed management specifically.
