对来自以色列和中国的分属Ｅｎｔｅｒｏｂａｃｔｅｒ，Ｐｓｅｕｄｏｍｏｎａｓ和Ｂａｃｉｌｌｕｓ三个属９个菌株的室内测试结果表明，其中几个菌株对Ｒｈｉｚｏｅｔｏｎｉａｓｏｌａｎｉ和Ｆｕｓａｒｉ－ｕｍｍｅｌｏｎｉ具有很强的拮抗能力和对几丁质具有很强的分解能力，其抗菌活性物质因对象菌的不同可分别表现抑菌作用或杀菌作用，并对高温煮沸具有相当的耐性。用荧光标记法对Ｅ．ｓｐ．ＩＣ１２７０在棉株体内的群体动态的监测结果表明，该菌在棉株体内特别是在根部可以很好地定殖，其数量在接种１个月后可增加２００倍。温室生测结果表明，Ｅｎｔｅｒｏｂａｃｔｅｒ和Ｐｓｕｄｏｍｏｎａｓ属中的一些菌株，对棉花立枯病（Ｒ．ｓｏｌａｎｉ），枯萎病（Ｆ．ｏｘｙｓｐｏｒｕｍｆ．Ｓｐ．ｖａｓｉｎｆｅｃｔｕｍ）黄瓜枯萎病（Ｆ．ｏｘｙｓｐｏｒｕｍｆ．ｓｐ．ｍｅｌｏｎｉ）和菜豆菌核病（Ｓｃｌｅｒｏｔｉｕｍｒｏｌｆｓｉｉ）具有明显的防治效果。认为土壤和植物内生细菌在病害生防上具有非常重要的潜在应用价值。
Laboratory tests on nine strains of Enterobacter, Pseudomonas and Bacillus from Israel and China showed that several of these strains were highly antagonistic to Rhizoetoniasolani and Fusari-ummeloni and strongly to chitin Decomposition ability, the antibacterial activity of the material due to the different bacteria can be the role of bacteriostatic or bactericidal effect, and high temperature boiling has considerable patience. E using fluorescent labeling method. sp. The results of population dynamics monitoring in cotton plants indicated that the strain could colonize in cotton plant especially in the roots, and its number could increase by 200 times after one month of inoculation. The results of greenhouse tests showed that some strains of Enterobacter and Psudomonas strains were resistant to R. solani, F. oxysporum f.Sp.vasinfectum and F. oxysporum f.sp. meloni, Sclerotium rolfsii has a significant control effect. It is considered that soil and plant endophytic bacteria have very important potential application value in pest control.
