Established Turf - General Information

Nutgrass ‘Nihilator is a selective postemergence herbicide for the control of broadleaf weeds, annual sedges, and yellow nutsedge in established turf. Nutgrass ‘Nihilator does not control grasses. Nutgrass ‘Nihilator is effective mainly through contact action; therefore, all plants must be thoroughly covered with spray. In California, Nutgrass ‘Nihilator is registered for use only in established turf to control yellow nutsedge.

Weeds controlled by Nutgrass ‘Nihilator in turf are annual sedges*, yellow nutsedge, spurweed*, lambsquarters*, Venice mallow*, shepherdspurse*, smartweed*, chickweed*, common groundsel*, ladysthumb*, jimsonweed*, galinsoga*, common purslane*, cocklebur*, beggarticks*, wild mustard*, wild poinsettia*, wild buckwheat*, velvetleaf*, Canada thistle*, and musk thistle*. Weeds suppressed by Nutgrass ‘Nihilator include: common ragweed*, giant ragweed*, wild sunflower*, and morningglory*. Some weeds not controlled include: purple nutsedge, pigweed, plantain, dandelion, onion/garlic, wood sorrel, and spurge.

Application Information

Nutgrass ‘Nihilator may be used on established bluegrass, fescue, bentgrass, bermudagrass, bahiagrass, centipedegrass, zoysiagrass, ryegrass, and St. Augustinegrass. Refer to Table 1, Application Rates for Established Turf for recommended rates of Nutgrass ‘Nihilator and volumes of water. Apply Nutgrass ‘Nihilator postemergently to weeds that are actively growing and under good soil moisture conditions. If desired control of yellow nutsedge or Canada thistle is not obtained with the first application, make a second application in 10-14 days or when new growth appears.

In the northern United States, yellow nutsedge can emerge from May through July, whereas in the southern United States, nutsedge and broadleaf weeds can emerge throughout the year. Therefore, initial applications should be planned when most plants have emerged. If new plants emerge later in the season, make a second application of Nutgrass ‘Nihilator in accordance with the label directions. In unmowed turf, make the first application after emergence but before yellow nutsedge, annual sedge, and Canada thistle are 8 inches tall. Annual broadleaf weeds should be no taller than 4 inches.

Thorough spray coverage of yellow nutsedge is essential for maximum control. For optimum control do not mow within 3 days before or after application. For sedges, do not mow within 5 days of application.

Mixing

Fill the tank of a thoroughly clean sprayer one-half to two-thirds full with clean water. Add Nutgrass ‘Nihilator and shake or stir the spray solution so that Nutgrass ‘Nihilator and water mix thoroughly. Add the remaining volume of water and shake or stir the spray solution to mix thoroughly. Mix only enough spray solution for one usage; a fresh spray mixture should be used each application.

Best if used with a surfactant such as Herbicide Helper.
