Abstract

Abstract: The effect of 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl oil dispersion（OD） on weed control in wheat field was studied. The wheat yield, the content of N-P-K and water were also analyzed after weed control. The results indicated that the efficacy of weed control was remarkable by 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl OD in wheat field. The control efficacy of compound formulation on Malachium aquaticum, Galium aparine, Vicia sativa and Beckmannia syzigachne was ranged from 91.5% to 97.3%, which was significantly higher than three individual herbicides. The accumulation of weed water and nutrients was significantly decreased after weed control. The wheat yield was 3 456.27 to 3 591.27 kg/hm² after treated with 26% mesosulfuron-methyl·florasulam· fluroxypyr-meptyl OD, which increased by 36.0%~41.2% compared to untreated control. Moreover, the yield income increased by 2 101.65~2 412.15 Yuan/hm².

Key words: mesosulfuron-methyl·florasulam· fluroxypyr-meptyl;, weed control effect, nutrient content, wheat yield
