Abstract/Contents:"The effect of halosulfuron-methyl on the growth of purple nutsedge was compared to bentazon, glyphosate and imazaquin in greenhouse trials. Halosulfuron-methyl controlled nutsedge at 36, 54 and 72 g/ha but was not completely effective at 18 g/ha. Injury from halosulfuron-methyl was similar to glyphosate ad imazaquin. Halosulfuron-methyl inhibited leaf elongation an dry weight accumulation, and then the leaves became chlorotic and desiccated. Bentazon caused leaf chlorosis and desiccation by at 3 DAT whereas injury symptoms had not appeared with glyphosate, imazaquin or halosulfuron-methyl. Bentazon did not inhibit regrowth so in effect this treatment only temporarily controlled top growth. Glyphosate controlled the purple nutsedge at all rates tested. Imazaquin was less effective than glyphosate although at the higher rates it effectively controlled nutsedge equal to glyphosate. Except for bentazon, each of the herbicides killed rhizomes, tubers and developing shoots. In field tests against a mature stand of purple nutsedge in a bermudagrass turf, halosulfuron-methyl decreased tuber viability and nutsedge populations. However, tubers capable of forming new shoots were present suggesting that the tubers escaped treatment becase they were no longer attached by viable rhizomes to treated shoots."
