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.

田间条件下昆虫病原真菌白僵菌对蚕豆病害发生的影响

 抽象的

几种子囊菌昆虫病原真菌，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，真菌白僵菌（BBK-1 菌株）在西西伯利亚的实验室和田间条件下成功定植蚕豆植物。与昆虫真菌的初生茎相比，通过植物的白僵菌对植物病原体具有显着更高的拮抗活性。播种前蚕豆种子处理降低了种子材料受植物病原体感染的水平，显着减少了根腐病的发生和流行。由于使用白僵菌，发现病害发展指数（巧克力斑病、白粉病、镰刀菌病和其他斑点病）有所下降。白僵菌对植物的有效性和持久作用为生物制品的创造、分子遗传学研究以及基于最大协同作用原理选择某些植物和真菌对开辟了新的机遇。
