Ortho Weed B Gon Weed Killer for Lawns Concentrate2 32 oz.

Mostly for eradicating burr clover. Your expectation should be that it will kill off or wilt about half the weeds. Directions call for a second application months later, but by waiting months later, the weeds make a comeback and you're pretty much back to square one. What I do - spray once. Wait 3 to 7 days, and if signs of weed life still exist, spray again! If possible, make the second (and possibly third) spraying a spot spraying, targeting the active weeds only. Stay at it! Be tenacious! It is worth it to me, to kill off those little spiky sticker balls! I've HAD IT with those things attaching to my family and friends' socks and shoes, stabbing into ankles, to be hitchhiking into the house! Once you rid your property of burr clover weeds, they will usually not reappear for years. Most effective by spraying in the Spring, when the clover begins growing and the burrs have not as yet developed/appeared. Weeded patches will of course turn brown, so seeding those patches weeks later is a good idea. Remember that this product enters the weed by being absorbed by the leaves, so generally it is best to NOT mow then spray. Allow the weeds to grow and leaf-out, THEN spray when leaves are apparent and have a reasonable surface area. WEED! BE GONE!
