Control many types of broadleaf weeds in your warm season and cool season grass using the Bonide Weed Beater Ultra. This product combines a contact and systemic herbicide together for a thoroughly effective weed killer. The innovative combination allows the first herbicide to begin controlling visible broadleaf weeds right away, while the systemic product remains active in the soil, eradicating weeds for several weeks. The spray can be used in fescue, Kentucky bluegrass, perennial ryegrass, bermudagrass, and zoysiagrass to control weeds such as clover, pearlwort, dandelion, and yarrow among others. Use the innovative hose end nozzle to evenly cover your grass, with no measuring or mixing needed. Connect a garden hose to one end of the nozzle, and spray your lawn in even sweeps, walking gradually. The product mixes with water as you spray, covering up to 21,000 square feet of cool season turfgrass or 42,000 square feet of warm season turfgrass. This highly effective herbicide works rapidly, and may be used when grasses are dormant as well as active. Keep your lawn weed free using this Weed Beater Ultra. Made in the USA.
