Abstract

Several ascomycetous entomopathogenic fungi, including species in the genera Beauveria, are plant symbionts/endophytes and are termed as endophytic insect-pathogenic fungi. It was shown that the fungus Beauveria bassiana (BBK-1 strain) successfully colonized Vicia faba bean plants in laboratory and field conditions of Western Siberia. The B. bassiana reisolate passed through the plants had significantly higher antagonistic activity against phytopathogens in comparison with the primary stem of entomopahogenic fungi. Pre-sowing faba bean seeds treatment reduced the level of infection of the seed material with phytopathogens, significantly decrease the development and prevalence of root rot disease. A decrease in the disease development index (chocolate spot, powdery mildew, fusariosis and other spots diseases) was found as a result of the use of B. bassiana. The effectiveness and prolonged action of B. bassiana on plants opens up new opportunities both in the creation of biological products and in molecular-genetic research and selection of certain pairs of plants and fungi based on the principle of the greatest synergy.

昆虫病原真菌白僵菌对田间条件下蚕豆 (Vicia faba) 病害发展的影响

摘要

几种子囊菌类昆虫病原真菌，包括白僵菌属的物种，是植物共生体/内生菌，被称为内生昆虫病原真菌。结果表明，白僵菌（BBK-1 菌株）在西西伯利亚的实验室和田间条件下成功地定殖了蚕豆植物。B. bassiana与昆虫病原真菌的主茎相比，通过植物的再分离菌对植物病原体的拮抗活性显着提高。播前蚕豆种子处理降低了种子材料对植物病原体的感染水平，显着降低了根腐病的发展和流行。发现由于使用B. bassiana导致疾病发展指数（巧克力斑病、白粉病、镰刀菌病和其他斑点病）降低。B. bassiana对植物的有效性和长期作用为生物产品的创造和分子遗传学研究以及基于最大协同原则的某些植物和真菌对的选择开辟了新的机会。
