Cool Season Grasses - such as Bluegrass, Fescue, and Rye:  To kill Dandelion, Wild onion, Pennywort, Plantain, Healall and similar weeds: use 8 to 13 fluid ounces in 6 gallons of water and apply with pump or hose-end sprayer or sprinkling can to 2,500 square feet of lawn.  For smaller areas - use 3 teaspoons in 2 quarts of water applied to 100 square feet.

To kill undesirable weeds such as Thistle, Bindweed, Dock and Ragweed, use 8 fluid ounces in 6 gallons of water (or 3 teaspoon in 2 quarts 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 quart 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 St. Augustine, Bahia, common Bermuda, Centipede, Zoysia, also for Bent:  Use a one-half rate which is 4 to 6-1/2 ounces in 6 gallons of water to treat 2,500 square feet (3 teaspoons in 4 quarts of water applied to 200 square feet).  Make two applications 30 days apart.  Do not spray grasses if stressed from heat, drought, etc. Slight turf yellowing 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 teaspoons of WEED WHACKER into an empty quart container with trigger sprayer.  Then add 30 fluid ounces of tap water.  Trigger Sprayer - Adjust spray nozzle to give coarse spray.  Aim at center of weed and spray to wet.  One application should be sufficient. Effects begin to show after a few days and weeds gradually die. A repeat application may be required in 4 weeks for hard-to-control weeds.
