Bioefficacy of Flufenacet and Sulfosulfuron Alone and in Combination Against Weed Flora in Wheat

Sulfosulfuron at 25 g ha_-1 being superior to its lower doses (15 and 20 g ha_-1) provided 87% control of Avena ludoviciana, Phalaris minor and Rumex retroflex in wheat resulting in yield and yield attributing characters statistically similar to weed-free check. Flufenacet at various doses alone or tank mixture with 2, 4-D Na failed to provide satisfactory control of weeds. Tank mixture of sulfosulfuron and flufenacet also did not provide any additional advantage over sulfosulfuron at 25 g ha_-1. Weeds growing throughout the crop season reduced the grain yield of wheat to the extent of 63.4%.
