Abstract: In order to seek weed control technology in soybean corn compound planting field, 6 kinds of herbicides were applied in soil sealing test at seedling stage after sowing. The results showed that 40% promethazine·acetonide wettable powder and 20% Flufop·Glyphosate dispersible oil suspension agent had a good control effect on broadleaf weeds. On the 30 th day after application, the control effects on broadleaf weeds were 99.31% and 96.76%, and the control effect ofthe fresh mass were 99.97% and 99.42%, respectively. Besides, the plant control effects on Ammannia baccifera. were 99.31% and 96.99%, control effect of the fresh mass were 99.97% and 99.30%, respectively. Each agent used in the treatment was safe for soybean and corn.
