| Abstract: | In order to discuss the control efficacy and safety of 75% tribenuron-methyl WDG on annual broadleaf weeds in spring wheat field ,field plot trials were conducted .The results showed that the suitable application period of 75% tribenuron-methyl WDG was 4-5 leaf stage of spring wheat seedling and the height of annual broadleaf weeds was below 5 cm ,the appropriate amount of effective ingredients was 18 .0-22 .5 g·hm^-2 ,it was safety in recommended dose for spring wheat .The total control efficacy on annual broadleaf weeds was 95 .9%-99 .2% and control effect of fresh weight was 97 .6% ~99 .7% after 30 d for applying . |
