Spray for weeds
A herbicide is a chemical substance used to kill unwanted plants, especially weeds.
Herbicides are essential tools in agriculture and landscaping, applied to fields, lawns, and gardens to eliminate vegetation that competes with desired crops or plants: The farmer sprayed herbicide along the fence rows.
Selective herbicides target specific plant types while leaving others unharmed.
