Command为美国FMC公司研制的新型除草剂。化学名称2-(2-氯苯)甲基-4,4-二甲基-3-异恶唑烷酮。分子式:C_(12)H_(14)C1NO_2。分子量239.7。使用剂型为含有效成分50％的浅褐色乳油,系由美国FMC公司提供。该药剂被植物根或芽基吸收后从植株下部向上部传导,抑制其叶绿素的合成,而大豆对其有降解作用。试验在位于黄河三角洲的国营广北农场农业实验站进行。试验地土壤为滨海盐化潮土,盐分含量0.1％。土质粘重。耕作层有机质1.53％,pH7.6。供试作物为夏大豆。前作物为冬小麦。夏大豆于1986年7月11日播种,随即按处理小区
Command for the United States FMC company developed a new type of herbicide. Chemical name 2- (2-chlorophenyl) methyl-4,4-dimethyl-3-isoxazolidone. Molecular formula: C_ (12) H_ (14) C1NO_2. Molecular weight 239.7. The use of formulations containing 50% of the active ingredient light brown cream, by the United States FMC company. The agent is absorbed by the plant roots or buds from the lower part of the plant conduction to the upper, inhibit the synthesis of chlorophyll, and its degradation of soybeans. The experiment was conducted at the state-run Guangbei Farm Experiment Station located in the Yellow River Delta. The test soil is coastal salinized soil with salt content of 0.1%. Soil sticky weight. Tillage layer organic matter 1.53%, pH7.6. The test crop for the summer soybean. The former crop is winter wheat. Soybean on July 11, 1986 sowing, then press the area
