Postemergent Control for Poa Annua, Ryegrass & Broadleaf Weeds in Warm-Season Turf
Dual-active sulfonylurea herbicide designed specifically for Bermudagrass and Zoysiagrass.
Negate® 37WG is a powerful postemergent herbicide formulated for selective weed control in established Bermudagrass and Zoysiagrass. As a sulfonylurea (ALS inhibitor) herbicide, it delivers broad-spectrum control at extremely low use rates, making it both highly effective and cost-efficient.
Negate is especially valuable for removing cool-season grasses such as Poa annua and overseeded ryegrass from warm-season turf, while also controlling a wide range of broadleaf weeds.
