Kill weeds down to the root without harming your lawn (when used as directed)! Ortho® WeedClear™ Lawn Weed Killer Ready-To-Use1 controls and suppresses over 250 types of weeds, including major broadleaf weeds (see label for list), dandelion, clover, oxalis, chickweed, and spurge, yet won't damage your grass (when used as directed). The formula is rainproof in hours and delivers visible results in 24 hours. The liquid herbicide enters through leaves and moves inside the weed down to the roots. To use, install the battery-powered Ortho® Comfort Wand from the side of the bottle to easily reach and spot-treat weeds with a continuous stream — no bending or pumping required! Best to apply when weeds are young and actively growing. Recommended for use on multiple lawn varieties including Kentucky bluegrass, perennial ryegrass, fescues, common bermudagrass, hybrid bermudagrass, bahiagrass, bentgrass, buffalograss, centipedegrass, zoysiagrass, and St. Augustinegrass (except Floratam).
