Herbicides are chemical substances used to control unwanted plants, commonly referred to as weeds, in agricultural and horticultural settings. These chemicals target specific biological processes in plants, inhibiting their growth and ultimately killing them. Herbicides are a key tool in modern agriculture, helping to increase crop yields by reducing competition from weeds. However, their use can also have negative environmental impacts, such as contamination of soil and water sources, and can harm non-target plant species and beneficial insect populations. Researchers in the field of herbicides study the efficacy, safety, and environmental impacts of these chemicals, as well as developing new formulations and application techniques to improve their effectiveness and reduce their negative effects.
