herbicides
Chemicals killing weeds
Herbicides are chemicals used to kill unwanted plants, especially weeds.
They may target specific plant types or kill vegetation indiscriminately.
Herbicides are essential tools in agriculture and landscaping: The farmer applied herbicide to the soybean fields.
Environmental concerns focus on runoff into waterways and effects on non-target species.
