Viral diseases and their damage causing significant loss to economically important crops have increased by several folds during the last decade. All the conventional approaches are not able to eradicate the viral infection. Therefore, there is a need to look for efficient and eco-friendly viral disease-preventive measures. The genomic material of the majority of deleterious viruses of higher plants is RNA. One of the possible measures to control viruses is the use of ribonucleases (RNases), which can cleave RNA in the viral genome. Based on this, we investigated the RNase activity of endophytic  Bacillus  spp., which can enrich in 10 3 –10 5  colony-forming units per gram of wet mass of aboveground part of potato plants. A high level of RNase activity was observed in the culture medium of  Bacillus thuringiensis  B-6066,  Bacillus  sp. STL-7,  Bacillus  sp. TS2, and  Bacillus subtilis  26D.  B. thuringiensis  B-5351 had low RNase activity but high ability to colonize internal plant tissues,  Bacillus  sp. STL-7 with high RNase activity have relatively low number of cells in internal tissues of plants.  B. thuringiensis  B-6066,  B. subtilis  26D, and  Bacillus  sp. TS stimulate RNase activity in potato plants for a long time after application. Strains with high ability to colonize internal plant tissues combined with high RNase activity reduced severity of viral diseases symptoms on plants and reduced the incidence of potato viruses M, S, and Y. It is worth noting that  Bacillus  spp. under investigation reduced the number of  Leptinotarsa decemlineata  Say. egg clusters and larvae on treated plants and showed antifeedant activity. This results in increase of potato productivity mainly in the fraction of major tubers.  B. subtilis  26D and  Bacillus  sp. TS2 combining endophytic lifestyle, RNase, and antifeedant activity may become the basis for the development of biocontrol agents for plant protection.
