近年来,随着除草剂的不断推广应用,极大的促进了农业生产力的发展,节约了大量的劳动力,但同时也带来相应的药害问题。2009年7月山东某农药公司,生产的20%辛·灭EC在销售棉区对棉花产生大面积药害,根据药害症状,判断药剂生产过程中可能有其他成份掺入,为了验证药害症状和药害原因,受该公司委托,根据排除法设计试验,分别配制含有20%辛·灭EC各组分的药剂,进行田间药害试验。药剂配制所用原料均取自20%辛·灭EC生产原料。由于初步估计是乳化剂造成的药害,因此在配制药剂过程中,重点对乳化剂进行了药害试验的排查。
In recent years, with the continuous popularization and application of herbicides, it has greatly promoted the development of agricultural productivity and saved a great deal of labor force, but at the same time, it has also brought about the problem of phytotoxicity. In July 2009, a pesticide company in Shandong Province, 20% of the production of sycamore EC produced large-area phytotoxicity on cotton in the cotton sales area. According to the symptoms of phytotoxicity, it may be judged that other ingredients may be mixed during the production of the medicament. In order to verify the phytotoxicity Symptoms and causes of injury, commissioned by the company, according to the exclusion of the design test, were prepared containing 20% synergistic EC EC components, field phytotoxicity tests. The ingredients used in the preparation of medicaments were all taken from 20% Xin · EC production materials. As a preliminary estimate of the damage caused by the emulsifier, so in the preparation of pharmaceutical process, focusing on the emulsifier phytotoxicity investigation.
