For superintendents seeking control of a host of summer and perennial weeds on some cool- and warm-season grasses, Nufarm recently launched Allstar, a broad spectrum herbicide with four active ingredients.
With the active ingredients 2, 4-D; quinclorac; triclopyr; and sulfentrazone, Allstar is labeled for control of 223 weeds on golf courses, athletic fields, cemeteries, parks and sod farms as well as a variety of residential and commercial applications.
Because it has four active ingredients, Allstar can provide visible results within a few hours of application. With 2,4-D, Allstar offers more consistent control of tap-rooted perennial weeds. Quinclorac targets crabgrass and increases overall control of broadleaf weeds, while triclopyr provides control on tough summer annual and perennial weeds, and sulfentrazone gives turf managers a tool for nutsedge control.
Allstar is registered for use in annual bluegrass, Kentucky bluegrass, tall fescue, tall fescue and annual ryegrass, all of which have high tolerance to each of the four active ingredients. It also can be used on creeping bentgrass, Bermudagrass, rough bluegrass, chewings fescue, fine fescue, hard fescue, red fescue and Zoysiagrass, all of which exhibit moderate tolerance to Allstar's ingredients.
All star should not be used on colonial bentgrass, seaside bentgrass, bahiagrass, buffalograss, carpetgrass, centipedegrass, dichondra, seashore paspalum or St. Augustinegrass.
