香草隆是新型高效低毒选择性取代脲类除草剂。一九七九年上海市农药研究所完成小试并通过鉴定;江阴农药厂于同年在上海市农药研究所的协助下开始中试规模的研制,并在全国各地进行药效试验。一九八0年通过中试鉴定,今年列入全国农药大田药效试验网,由十七个省市级农科院负责试验。现将香草隆的性能及应用介绍如下: 一、理化性质:原粉为白色针状结晶,无刺激性气味。在pH_2—10范围内稳定,对热、紫外光稳定,在50℃±1℃时贮藏四周含量基本上无变化,在1N的盐酸中煮沸6小时分解。在水中溶解度为1.7ppm。
Vanillin is a new type of high efficiency and low toxicity selective urea herbicide. In 1979, Shanghai Pesticide Research Institute completed a small test and passed the appraisal. Jiangyin Pesticide Factory started the pilot scale development in the same year with the help of Shanghai Pesticide Research Institute and conducted the efficacy test in all parts of the country. In 1980 passed the pilot appraisal, this year included in the national pesticide field efficacy test net, by the seventeen provincial-level Academy of Agricultural Sciences is responsible for testing. The vanillin performance and application are introduced as follows: First, the physical and chemical properties: The original white needle crystal, non-irritating odor. Stable in the range of pH_2-10, stable to heat and ultraviolet light, basically unchanged in four weeks at 50 ℃ ± 1 ℃, decomposed in 1N hydrochloric acid for 6 hours. Solubility in water is 1.7ppm.
