Weed killers that eliminate clover include mecoprop and dicamba, which are used in many weed-and-feed and weed control products. The choice of which weed killer to use depends on the scope of the weed problem.
Mecoprop is often sold in combination with other formulas and is rarely used by itself. Mecoprop is used in common weed killers such as Weed-B-Gon and 2 Plus 2 Ortho. Dicamba is also generally used in combination with other active ingredients and is chosen for difficult weed control situations. It is a very potent weed killer and is known to damage small trees and shrubs. It can be found in products such as Trimec and Super Trimec.
