| Abstract/Contents: | "Field studies were conducted in Kansas and Maryland to compare the safety and efficacy of halosulfuron-methyl (HM) and bentazon for topkill of yellow nutsedge (Cyperus esculentus L.). Kentucky bluegrass (Poa pratensis L.) and creeping bentgrass (Agrostis palustris Huds.) treated with single (in Kansas) or sequential (in Maryland) HM (35 to 140 g*ha-1) or bentazon (1120 or 1680 g*ha-1) applications exhibited little injury, and treated turf had acceptable quality in all studies. Bentazon caused an unacceptable reduction in perennial ryegrass (Lolium perenne L.) quality at >=5 weeks after treatment in four of five tests. Perennial ryegrass quality declined linearly with increasing HM rates (between 35 and 140 g*ha-1). In Maryland, HM (>=70 g*ha-1) elicited unacceptable perennial ryegrass quality for 2 or 3 weeks; however, in Kansas, quality wasunacceptable for approximately 1 week. In Kansas, yellow nutsedge topkill by HM (70 kg*ha-1) ranged from 52% to 97%. A single HM application (35, 70, or 140 kg*ha-1) provided >97% topkill in Maryland. Yellow nutsedge topkill by bentazon (1680 g*ha-1) generally was inferior to that by HM (70 g*ha-1)." |
