Recommendations for chemical control of noxious weeds using backpack and hand held sprayers

Basic herbicide information and recommendations

Herbicides can be divided into two main categories. Non-Selective herbicides generally target all plants including grasses while Selective Broadleaf herbicides target only broadleaf plants and generally do not harm grasses. There are many Non-restricted Use herbicides available in quantities of one gallon or less, whereas Restricted Use herbicides require a pesticide applicator license for purchase. If you are interested in obtaining a pesticide applicator license contact the WSU Extension Office for information and study materials. Your chemical dealer or County Weed Board can recommend herbicides for your particular situation.
