herbicide
Meaning: A chemical substance used to destroy unwanted vegetation, especially weeds that compete with crops.
Herbicides are the most widely used category of pesticide in modern agriculture. They can be selective (targeting specific plants) or non-selective (killing all vegetation). Glyphosate, the active ingredient in Roundup, is the world's most commonly used herbicide and has been the subject of significant controversy regarding potential health effects.
