From 1991 to 1992, 6 units (units) in 6 counties (cities) were used to test and demonstrate the herbicide we used. The results showed that the control effect of B-A mixture on monocotyledonous weeds was 86.4%, that of dicotyledons was 87.5% The average fresh weight control efficiency reached 94.2%, which was better than that of the imported herbicide Dole and so on, and had no adverse effect on corn and the next crop of wheat, with high efficiency, safety, economy and convenience
