Ortho® GroundClear® Super Weed & Grass Killer1 is used to kill 175 types of tough weeds and grasses including crabgrass, dandelion, nutsedge, and oxalis (as listed). Apply this ready-to-use spray around landscape areas, patios, walkways, gravel, mulched areas, along houses and fence lines, and on driveways when weeds are actively growing and the air is calm. It's fast-acting - weeds absorb it on contact so you'll start to see weeds and grass wilt within hours and completely die off in 1-2 weeks.
