燕麦畏(Triallate)是美国孟山都(Monsanto)公司制造的除草剂,化学成分是:S-2,3,3-三氯烯丙基??-二异丙基硫代氨基甲酸酯.具有挥发性,25℃时在水中溶解度4ppm,加工剂型为40%燕麦畏乳油.在美国、加拿大、澳大利亚等国家应用其防除农田野燕麦. 燕麦畏的使用技术,在小麦播种后出苗前施药,耙混表土1-3厘米.这种使用方法在雨水多,土壤潮湿和一些冬麦区应用,效果比较良好;但气候干旱时对药效影响很大. 1970年以来,我们根据青海高原的自然特点、野燕麦发生特性、以及小麦的种植生长情况,结合燕麦畏的性质,进行了田间应用技术的研究.改播后苗前施药浅混土为种前施药深混土,和秋施药以及苗水期施药,使燕麦畏除草效果稳定在90%左右,且对小麦安全,增产显著,在大面积示范推广后受到广大社员的欢迎.
Triallate is a herbicide made by the Monsanto Company of the United States and its chemical composition is: S-2,3,3-trichloro-allyl-diisopropylthiocarbamate with volatile Its solubility in water is 4ppm at 25 ℃, 40% oatmeal EC is used as a processing agent in the United States, Canada, Australia and other countries to control the use of wild oat and farmland oats. Mixed surface 1-3 cm. This method of use in the rain, soil moisture and some winter wheat area application, the effect is relatively good; but when the climate has a great influence on the efficacy of pesticides. Since 1970, we based on the natural characteristics of Qinghai Plateau , The occurrence characteristics of wild oats and wheat planting and growth, combined with the nature of oatmeal, field application techniques were studied. As well as the application of water during the seedling stage, so that the weed control effect of oatmeal stabilized at about 90%, and the safety of wheat, yield significant, after a large area demonstration and promotion by the majority of members of the welcome.
