At present, the commonly used acetochlor herbicides on the production of soybean safety is poor, drug harm, resulting in late maturity of soybean glutinous, low yield. The amide herbicide Jindul is a high herbicide based on original Dole EC and refined by refining, and added a safener. It has the characteristics of low dosage, good safety and good weeding effect. In 2003, we conducted a pilot demonstration. The results are as follows. 1. Materials and methods Tested pharmaceuticals: 196% of Jinduer EC was supplied by Swiss Syngenta. 248% Clenbuterol is supplied by FMC Corporation. 350% fast-acting wettable powder is provided by Japan Sumitomo Corporation. 450% Le Feng Bao EC is provided by Hebei Xuanhua Pesticide Factory. 590% acetochlor EC is provided by Zhalantun, Inner Mongolia. 650% acetochlor is supplied by Kunshan Pesticide Factory. 2. The experimental treatment site was meadow sandy loam soil, with an organic matter content of 3.1% and a pH value of 6.1. The soybean variety was Baofeng No. 7. May sowing on the 11th, spraying on the 13th. 300 kilograms of water per hectare are sprayed with a sprayer. The main weeds in the field include valerian, sorrel, sorghum, and cocklebur. Each hectare is treated as follows: 196% of Jinduer Emulsion 1050ml + Guanglingling 675ml + 60g. 296% Jin Dole 1200 ml + Guang Ling Ling 675 ml + fast 60 g. 390% acetochlor 1350 ml + Guang Ling Ling 675 ml + fast 60 g. 450% acetochlor 2250 ml + Guang Ling Ling 675 ml + fast 60 g. 50% Le Feng Bao 3150 ml + Guang Ling Ling 675 ml + fast 60 g. There is a total of 6 treatments in the non-application area, which are randomly arranged without duplicates. Each processing area is 10,000 square meters, and a total of 3 blanks are maintained in each of the 5 treatment areas with 60 square meters per point. 3. Results Analysis Tests have proved that Jinduer compounded 1050 to 1200 ml per hectare and applied twice a day before sowing soybean seedlings so as to control alfalfa up to 100%; and the effect of controlling alfalfa leaves, alfalfa and cocklebur was 100%. . The use of high-purity acetochlor to reconstitute 1350 ml, control of alfalfa up to 99.2%, control sorrel leaves, alfalfa, Xanthium effect up to 100%. Acetochlor compounded with 2250 ml, control of alfalfa up to 98.4%, control of alfalfa up to 88.8%, control sorrel leaves, alfalfa, Xanthium effect up to 100%. The use of Le Feng Po compound 3150 ml control of alfalfa up to 99.2%, control sorrel leaves, alfalfa, Xanthium effect up to 100%. For the safety of soybeans and observations at the seedling stage, Jinduer had no symptoms of injury during the cotyledonary and true leaf stages, and there was a slight shrinkage at the tip of the middle leaf during the compound leaf stage. The other two leaves were safe. The combination of acetochlor and LeFonBao has yellow-brown edges at the cotyledonary stage and severe shrinkage at the true leaf stage and compound leaf stage. In conclusion, 96% of Jinduer EC blended with 1050 to 1200 ml per hectare is safe for crops at seedling stage, and 100% for alfalfa grass, acid leafhopper, alfalfa, and cocklebur; the ratios of aboveground and underground parts of crops are respectively The control increased by 14.4% to 15.2% and 8.2% to 12%. Jindal is suitable for use in meadow sandy loam at a dose of 1050 ml/ha.
