potato disease is widespread in the world and causes substantial yield and quality losses in potato. This study aimed to evaluate the efficacy of entomopathogenic fungi and in the inhibition of potato complex disease. The efficacy of the entomopathogenic fungi and in the defense of potato against disease (stem cancer, black scrulf and other forms of manifestation on tubers) was estimated under field conditions in Western Siberia. Preplanting treatment of the tubers with decreased disease in the stems and stolons. At the same time, treatment with did not cause a decrease in disease in these organs. However, both fungi decreased the sclerotium index on the tubers of new crops. We demonstrated two mechanisms of inhibition of by and , including (1) direct effect, expressed as inhibition of sclerotium formation in cocultivation assays, and (2) indirect effect, which is associated with increased peroxidase activity in potato roots under the influence of colonization by entomopathogenic fungi. We suggest that the treatment of seed tubers with can effectively manage disease during the plant vegetative season and that both fungi significantly improve the quality of the new tuber crop.
马铃薯病害在全球广泛存在，会导致马铃薯产量大幅下降和品质受损。本研究旨在评估昆虫病原真菌对马铃薯复合病害的抑制效果。在西西伯利亚的田间条件下，评估了昆虫病原真菌对马铃薯抵御病害（茎癌、黑痂病以及块茎上的其他表现形式）的效果。用[具体真菌名称1]对块茎进行种植前处理，可降低茎和匍匐茎中的[病害名称]发病率。同时，用[具体真菌名称2]处理并未使这些器官中的[病害名称]发病率降低。然而，两种真菌均降低了新作物块茎上的菌核指数。我们证明了[具体真菌名称1]和[具体真菌名称2]抑制[病害名称]的两种机制，包括：（1）直接作用，表现为在共培养试验中抑制[病原菌名称]菌核形成；（2）间接作用，这与昆虫病原真菌定殖影响下马铃薯根系中过氧化物酶活性增加有关。我们认为，用[具体真菌名称1]处理种薯可在植物营养生长季节有效防治[病害名称]，且两种真菌均能显著提高新块茎作物的品质。
