Herbicides

Herbicides are chemical substances used to kill plants. They may be non-selective and kill all vegetation to which they are applied or sterilize the soil. Others which destroy one type of plant without appreciably affecting another are called selective herbicides.

Weed-and Feed lawn fertilizers are examples of fertilizers with selective herbicides incorporated. They destroy broadleaved weeds but do not harm grasses. Selective herbicides, of which there are many, are widely used today in a number of agricultural crops and in maintaining golf courses.
