Abstract

The research is aimed at studying the antagonistic relationships of five isolates of the genus Trichoderma fungi in relation to the Alternaria sp. fungus. The pathogen was isolated from diseased walnut leaves. In the work was used the method of double cultures on agar media. As a result, 160 the inhibition rate of Alternaria pathogen by Trichoderma fungi was determined. For isolate №3 the rate was 90%, for isolate №2 - 85%, isolate №4 inhibited the pathogen by 75%, isolate №1 - by 65%. Isolate №5 and strains T.virens and T. lignorum suppressed the growth of Alternaria by 40-50%.

与Alternaria Sp病原体相比，Trichoderma属新真菌绝缘体的对抗性

本研究旨在研究5株木霉属真菌与Alternaria sp.真菌的拮抗关系。从患病的核桃叶片中分离到病原菌。本研究采用琼脂双层培养法。测定了木霉真菌对稻瘟病菌的抑制率。分离物3的抑制率为90%，分离物2 - 85%，分离物4抑制病原体75%，分离物1 -抑制病原体65%。分离物5号和菌株T.virens和T. lignorum抑制交替菌生长40-50%。
