use | selective pre-bud soil treatment agent. It works through absorption and conduction by roots or young stems. The mechanism of action is to inhibit nucleic acid metabolism and protein synthesis. Mainly used for corn, cotton, alfalfa, kidney beans, peas, flax, potatoes, sugar beets, sunflowers, citrus, pineapples, strawberries, grapes and ornamental plants, to control arabia sorghum, creeping ice grass, barnyard, wild oats, Cyperus, Setaria and some broad-leaved weeds such as Portulaca oleracea, Chenopodium, and Stellaria. The recommended dosage is 10~30g/100 m2. In order to prevent chemical volatilization loss, the medicine can be mixed into the soil by machinery and irrigated. |
Production method | The phosgene reacts with dipropylamine to generate dipropylcarbamoyl chloride, which then reacts with ethanethiol to form the enemy. It can also be prepared by the reaction of dipropylamine and ethylthionoyl chloride in the presence of NaOH, or by the reaction of dipropylamine with diethyl sulfate and COS. |
