Scotts® Turf Builder® Triple ActionI provides three benefits in one bag. This 3-in-1 formula kills and prevents listed weeds, all while feeding and strengthening your lawn. It kills listed broadleaf weeds like dandelion and clover, and prevents crabgrass for up to 4 months. It also prevents barnyardgrass, fall panicum, foxtail, and annual bluegrass. Scotts® Turf Builder® Triple ActionI is for use on Bahiagrass, Centipedegrass, Kentucky Bluegrass, Perennial Ryegrass, Bermudagrass, Tall Fescue, and Fine Fescue. Apply when dandelions are actively growing. For spring application, apply when daytime temperatures are consistently between 60°F and 80°F and before the 3rd or 4th mowing. A fall application may be made to control fall-germinating winter weeds and cool season perennial weeds. Make sure your grass is wet from dew or sprinkling before applying, as this helps particles adhere to weed leaves to produce the best results. We recommend using a Scotts® spreader to apply this product. For Scotts® broadcast/rotary spreaders, use a setting of 3 ¼. For Scotts® drop spreaders, use a setting of 6. After 24 hours, water the lawn to wash particles onto the soil to prevent the germination of grassy weeds. One 11.31 lb. bag covers 4,000 sq. ft.
