You can kill weeds without harming your lawn with Ortho WeedClear Weed Killer for Lawns Concentrate. This weed killer kills over 250 common weeds, including dandelions, clover, poison ivy, sumac, chickweed, and dollarweed (see product label for complete weed list). It is made especially for residential lawns and contains three proven ingredients to specifically target and destroy other common lawn weeds, without harming your grass.

This herbicide works by entering weeds through their leaves, and moves throughout the plant to kill all the way down to the root. You'll see visible results in hr, and it becomes rainproof within one hr upon drying. Easily apply this concentrated formula with an Ortho Dial N Spray or tank sprayer. People and pets may enter the treated area after the spray has dried.

For best results, use when weeds are small and actively growing in the spring or fall. One 1-gal bottle treats up to 16,000 sq. ft. *When used as directed.
