The susceptibility to cucumber mosaic virus (CMV) infection causes a reduction in fruit yield and vigour of tomato (Lycopersicon esculentum L.) plants, but experimental evidence from using plant growth promoting rhizobacteria (PGPR) against CMV is scarce. We examined the effects of some PGPRs on yield production responses in tomato after and before infection with CMV. A culture mix of three PGPRs (Pseudomonas aeruginosa, Stenotrophomonas maltophilia and Bacillus licheniformis) were utilized in greenhouse experiments. Tomato test plants subjected to PGPR prior to infection showed a significant yield increment and virus titer was demolished to the minimum. Tomato plants treated with combinations of the PGPRs had yielded a greater number and a higher fresh weight of tomato fruits. In addition, tomato plant dry weight was significantly increased compared to untreated healthy plants.
