This concentrated formula kills down to the root, with overnight results. It controls all major broadleaf weeds, including dandelion, chickweed and clover (see product label for complete list). This product is rainfast in 6 hours, so it won't wash off. For best results, mow before treating weeds with Spectracide Weed Stop For Lawns Concentrate.
