高粱是我区种植面积较大的一种作物,每年种植约80万亩左右,特别是忻州、定襄、原平、代县每年种植面积约占粮田面积的10％左右。七十年代防治高粱蚜一般都用1059、乐果,个别地方还用3911等农药,防治方法大多采用喷雾、涂茎、熏蒸,效果并不理想。近几年来大多采用异丙磷农药,效果虽好,成本较高,且污染环境。为了尽快解决代替农药问题,省农科院向我区提供5％甲拌磷颗粒剂。甲拌磷颗粒剂是矸面或砂颗粒吸附甲拌磷被包蜡衣制作而成的一种新剂型,具有胃毒、触杀和熏蒸作用,也有安全可靠、残效期长、使用方便等优点。1984年8月,我站先后在定襄县横山大队、忻州市河拱大队、原平县永兴大队作了不同农药药效、用量及施药方法等试验,结果5％甲拌磷颗粒剂效果较理想。同年在高粱蚜大发生时期,我站先后进回5％甲拌磷颗粒剂64吨,在发生区普遍推广使用,
Sorghum is a crop with a larger planting area in our region. About 800,000 mu are planted each year. Especially Xinzhou, Dingxiang, Yuanping and Daixian have an annual planting area of about 10% of the total grain area. Seventies sorghum aphids are generally used 1059, dimethoate, 3911 and some other places also use pesticides, prevention and control methods are mostly used spray, coating stems, fumigation, the effect is not satisfactory. In recent years, mostly using isoprofos pesticide, the effect is good, the cost is high, and pollute the environment. In order to solve the problem of substituting pesticides as soon as possible, the provincial Academy of Agricultural Sciences provides 5% phorate granules to our district. Phorate particles are gangue or sand particles adsorbed Phorate paraffin wax clothing made of a new dosage form, with stomach poisoning, contact and fumigation, but also safe and reliable, long residual period, easy to use and so on. In 1984 August, I station in Hengxiang Battalion in Dingxiang County, Xinzhou City River arch brigade, Yuanping County Yongxing brigade made a different pesticide efficacy, dosage and application methods and other tests, the results 5% phorate effect More ideal. In the same year in the sorghum period of aphis occurred, I have stepped back 5% phorate particles 64 tons, in the area of widespread promotion,
