石硫合剂由美国陶氏化学公司于1907年创制,属广谱性、虫病兼治的无机液体农药。由于人工熬制,不易保管、贮存和运输,仅为作坊式生产。近年来,其优良的杀菌、杀虫、杀螨活性及低毒、低残留等特点,重新引起一些国家的重视。日本松尾化成株式会社首先研制成结晶石硫合剂。国内经多年努力,现已完成年产量500～1000吨生产线,正式投入工业化生产。石硫合剂的毒性及毒作用机理,迄今未见公开报道,结晶品的主要成分亦为多硫化钙,但其分子结构与人工熬制品的多硫化钙分子结构不尽相同,人 Stone sulfur mixture by the United States Dow Chemical Company in 1907 created, is a broad spectrum, insect-resistant inorganic liquid pesticides. As a result of artificial brewing, not easy to custody, storage and transportation, only for the workshop-style production. In recent years, its excellent bactericidal, insecticidal, miticidal activity and low toxicity, low residual characteristics, re-attracted some countries attention. Matsuo Chemical Co., Ltd. of Japan first developed a crystal lime sulfur mixture. After many years of hard work in China, we have completed the production line of 500-1000 tons annual output and officially put into industrialized production. Toxicity and toxic mechanism of lime sulfur mixture, so far no public reports, the main component of crystalline products are also calcium polysulfide, but its molecular structure and artificial boil products of calcium polysulfide molecular structure is not the same person
