【摘要】 就大白菜根肿病(plasmodiophoa brassicae Woron)病原分类地位、危害现状、生物防治及其抑菌机理进行了综述。国内外研究机构对大白菜根肿病生物农药真菌、放线菌、芽孢杆菌等方面均有研究,已见报道多株链霉菌对根肿病有较好的防病效果,有待进一步研究开发。芸薹根肿菌以休眠孢子萌发作为其侵入十字花科蔬菜寄主病害循环的第一步,进入寄主组织后则以游动孢子为主要为害形态,存在无性短循环阶段,病害循环复杂。抑制休眠孢子萌发可以作为防治根肿病的主要手段之一;以休眠孢子为切入点开展根肿病研究已成为研究热点。更多还原

【Abstract】 The taxonomic status, damage status, biological control and anti-bacteria mechanism of Chinese cabbage clubroot disease were reviewed. Some strains from fungi, actinomycetes and Bacillus as biological pesticide against Chinese cabbage clubroot disease were studied by the researchers in the world. It had been reported that many Streptomyces had preventive control effects on clubroot disease, which needed further research and development. The first step of the disease cycle in the cruciferous vegetable host was the germination of dormant spores of Brassica brassicae. When it entered the host tissues, the zoospores would be the main damage form, and there was also a short asexual cycle stage, so the disease cycle was complex. Inhibiting dormant spore germination could be one of the main method to control club-root disease. Taking dormant spores as a targeting point to control Chinese cabbage clubroot disease had become a hot spot of interests from experts in various countries.更多还原
