What type of pesticide is used to kill weeds?

Herbicides are specifically designed to control unwanted plants or weeds. They work by targeting various growth processes in plants, often disrupting photosynthesis or cell division, leading to the death of the weed. This makes them an essential tool in agriculture for managing crop fields and ensuring that crops have the optimal conditions for growth without competition from weeds.

In contrast, insecticides are intended to target and control insect pests, while fungicides are used to combat fungal diseases in plants. Nematicides specifically target nematodes, which are microscopic worm-like organisms that can harm plant roots. Each of these other pesticide types serves a distinct purpose in agricultural pest management, focusing on different groups of organisms that can adversely affect plant health.
