Cool Season Grasses: In Bluegrass, fescue, and rye: To kill dandelion, wild onion, pennywort, plantain, healall, and similar weeds: use 8 to 13 fluid ounces in 6 gal. of water and apply with pump or hose-end sprayer or sprinkling can to 2500 sq ft. of lawn. For smaller areas – use 3 tsp in 2 qt of water applied to 100 sq ft.
To kill undesirable weeds such as thistle, bindweed, dock and ragweed, use 8 fluid ounces in 6 gal of water (or 3 tspn in 2 qt of water), and apply directly to plants, wetting them thoroughly.
To kill undesirable plants such as poison ivy and poison oak, use 2 fluid ounces in 1 qt of water and drench plants when they are fully leaved. Repeat in about 4 weeks if necessary. Certain hard-to-control weeds such as poison ivy, poison oak and english daisy may require a fall application.
Warm Season Grasses: On st. augustine, bahia, common bermuda, centipede, zoysia, and bent: Use a one-half rate which is 4 to 6-1/2 oz in 6 gal of water to treat 2500 sq ft (3 tspn in 4 qt of water applied to 200 sq ft). Make two applications 30 days apart. Do not spray grasses if stressed from heat, drought, etc. Slight turf-yellowing may occur, but should disappear after about 1 week.
Note: Some hybrid bermuda grasses may be sensitive to this product. Contact your local Extension Service weed control specialist.
For Spot Treatment: Put 3 tsp of Weed Whacker into an empty quart container with trigger sprayer, then add 30 fluid ounces of tap water.
