What type of pesticide is specifically designed to kill weeds?

Herbicides are specifically formulated to target and eliminate unwanted plants, commonly referred to as weeds. They function by interrupting the growth processes of these plants, either by inhibiting their ability to photosynthesize, promoting abnormal growth, or affecting their nutrient uptake. This targeted action allows herbicides to be effective in controlling weed populations in various settings, including agricultural fields, gardens, and lawns, without significantly harming other plants.

In contrast, insecticides are designed to kill or control insect pests, fungicides target fungal pathogens, and rodenticides are formulated for the control of rodents. Each of these other types of pesticides serves a distinct purpose that does not involve weed management, thereby reinforcing the unique role that herbicides play in pest control.
