Celsius WG Herbicide is applied at 0.113 oz per 1000 sq ft for Virginia Buttonweed on St. Augustine lawns.
For spot treatments, mix 0.057-0.113 oz (1.6-3.2 g) of Celsius WG Herbicide per gallon and apply until weeds are wet. One gallon of spray solution will treat up to 1000 sq ft. Per the product label, a second application of this product may be needed for control. If weeds are showing signs of recovery, make a second application 2-4 weeks after the first.
