SU374784A1 (en) | L2 The proposed compounds have high herbicidal activity and can be used to selectively control weeds in rice and sugar beet 10 crops. Recommended doses are in the range of 1–10 kg! Ha. The compounds can be applied both before and after the emergence of plants. The forms of application of these compounds are common: solutions, emulsions, suspensions, pastes, 15 powders, etc. They are prepared by well-known methods - common in the preparation of preparative forms of pesticides. The proposed compounds are based on the interaction of 2,3-dnhalide benzoquinone with diazomethane or alkyl diazo compound, as well as with alkyl nitrile oxide. In addition, they are produced by reacting compounds of general formula I, in which X and Y are a hiloid, with ammonia or primary ammonia, as well as the interaction of compounds of general formula 1, in which X and "Y" are my substituted amino group, with the corresponding acylnuyuschim 30 ageitami, as well as with nitric acid. | |
