Weed Science is knowledge about unwanted plants and about methods to control such plants. The concept “weeds” probably was born when man first learned that desirable plants would grow better if surrounding plants were killed. Knowledge of elementary weed control began when man learned that unwanted plants died if they were separated from the soil. Thus rudimentary Weed Science is as old as man's efforts to grow crop plants.
