西瓜枯萎病是一种毁灭性的土传病害,该病防治难度较大,为寻找无公害的理想防治方法,以达到在生产上控制和减轻此病的危害,美国 Bergstrom 教授等在1983年提出:用诱导因子通过激活植物的天然防御机制能使植物免受病原物危害或减轻危害。国内吴洵耻等报道,预先接种棉花黄萎病菌的弱毒菌系,可较好地抑制致病菌的蔓延.本文为我们在1991年使用棉花等作物上的几种尖孢镰刀菌诱导西瓜抗枯萎病的初步研究,现将结果总结如下。 Watermelon Fusarium wilt is a devastating soil-borne disease, prevention and treatment of the disease more difficult, in order to find the ideal method of pollution prevention and control in order to achieve the control of production and reduce the harm of the disease, the United States Bergstrom et al proposed in 1983 : Induction of plants with pathogenic or harm-reducing plants by using natural defense mechanisms that activate plants. Domestic Wu shameful reports, pre-inoculated with Verticillium dahliae weak attenuated bacterial strains, can better inhibit the spread of pathogens.This article for us in 1991 using cotton and other crops Fusarium oxysporum-induced watermelon Fusarium wilt preliminary study, the results are summarized below.
