Vascular wilt diseases caused by Verticillium dahliae Kleb. are difficult to control and lead to increasing losses of many crops worldwide. It can cause disease on not only horticultural crops but also many economically important crops such vegetables, legumes, forest trees, woody and herbaceous plants. Reasons of this situation are various: (i) the specialization of crop production resulted in the accumulation of the pathogen in the soil, especially monoculture production; (ii) the lack of an efficient and safe soil fumigation method; (iii) the production in large amounts of survival structures—microslerotia and melanized hyphae that are resistant to chemical and biological degradation.

Due to the lack of effective synthetic agents for eradication of V. dahliae from soil, considerable interest in this paper has been focused on biological control, especially the selection of microorganisms with mycoparasitic activity towards V. dahliae microsclerotia, that can decrease their number in soil. The main attention is paid on the Trichoderma fungi, non pathogenic Fusarium spp., Talaromyces flavus and bacteria Bacillus spp., Pseudomonas spp. and Streptomyces spp. that are discussed in this review. In this work the suppressive effect of organic amendments against this soil-borne pathogen is also mentioned. In addition biofumigation using toxic plant materials, which is an approach to the soil-borne pathogen management could be an effective method to control diseases caused by V. dahliae.

土壤传播真菌病原体的管理 - Verticillium dahliae Kleb。引起血管萎蔫病

由大丽轮枝菌引起的血管枯萎病。难以控制并导致全球许多作物的损失增加。它不仅可以对园艺作物造成疾病,还可以对许多经济上重要的作物造成疾病,例如蔬菜、豆类、林木、木本和草本植物。造成这种情况的原因是多方面的:(i)作物生产的专业化导致病原体在土壤中的积累,特别是单一栽培生产;(ii) 缺乏有效和安全的土壤熏蒸方法;(iii) 大量存活结构的产生——抗化学和生物降解的微菌核和黑色化菌丝。

由于缺乏从土壤中根除大丽花的有效合成剂,本文的相当兴趣集中在生物防治上,特别是选择对大丽花微菌核具有真菌寄生活性的微生物,这可以减少它们在土壤中的数量. 主要关注的是木霉属真菌、非致病性镰刀菌属、黄踝节菌属和细菌芽孢杆菌属、假单胞菌属。和链霉菌属 本评论中讨论的内容。在这项工作中,还提到了有机改良剂对这种土传病原体的抑制作用。此外,使用有毒植物材料进行生物熏蒸,这是一种土壤传播病原体管理方法,可能是控制大丽花弧菌引起的疾病的有效方法。
