辽宁省棉麻研究所于一九六○年从营口县汤池地区草炭土中分离出一种放线菌——抗生菌“507”。“507”的性质、作用及使用方法与“5406”基本相同,其特点是:抗克性强,对棉花苗期病害及枯、黄萎病有较好的防治效果。一九六一年他们用“5406”、“G4”、“507”防治棉花黄萎病,试验结果:发病率分别为19.7%、17.6%、6.2%。一九六三年再次以“507”作基肥(每亩施棉籽饼66斤)和 In 1960, Liaoning Institute of Cotton and Maize isolated an actinomycete-antibiotic “507” from peat soil in Tangchi area, Yingkou County. The nature, function and usage of “507” is basically the same as that of “5406”, which is characterized by its strong anti-gram and good control effect on cotton seedling diseases, wilt and verticillium wilt. In 1961 they used “5406”, “G4” and “507” to prevent and control cotton Verticillium wilt. The test results showed that the incidence rates were 19.7%, 17.6% and 6.2% respectively. In 1963, it again used “507” as the basal fertilizer (66 kg of cottonseed cake per acre) and
