Application of biopesticides of microbial origin against phytopathogens

Abstract

The inventions relate to agriculture - the use of Bacillus velezensis CNMN-BB-12 and Trichoderma atrobruneum CNMN-FD-25 strains as a source of bioactive substances for combat phytopathogens: B. cinerea, Alt. alternata, A. niger, F. solani, F. oxysporum, C. michiganensis, E. carotovora, X. campestris, A. tumefaciens. According to the invention, for combating phytopathogens, exometabolite solutions of the mentioned strains can be used for seeds treating before sowing, but also during the vegetative period of crop plants. The use of exometabolites of Bacillus velezensis CNMN-BB-12 and Trichoderma atrobruneum CNMNFD- 25 strains contributes to the fight against phytopathogens of fungal and bacterial origin, exceeding the control by 25-50%. The inventions were developed within project 20.80009.7007.09 „Conservation and exploitation of microbial biodiversity as a support for the development of sustainable technologies and agriculture, integration of science and education”, funded by NARD, Republic of Moldova.
