The effect of six bacteria Bacillus amyloliquefaciens, Curtobacterium sp., Staphylococcus epidermidis, Stenotrophomonas rhizophila, Pseudomonas sp., and Stenotrophomonas sp. strain LU2 on Meloidogyne javanica has been investigated. In the egg hatching test in laboratory conditions 8 days after inoculation, respectively Curtobacterium sp. with 61%, B. amyloliquefaciens with 46%, and Stenotrophomonas sp. with 26% showed the most control effect. In testing the number of live larvae in laboratory conditions, 3 days after inoculation, respectively Curtobacterium sp. with 43%, B. amyloliquefaciens with 32%, and Stenotrophomonas sp. with 8/5% showed the most control effect. In the growth indices related to the greenhouse among the infected and healthy treatments, the treatments (with and without nematode - Curtobacterium sp.) in the plant height index respectively with 16, 22%, in the root length index with 20, 34% in plant fresh weight index with 40, 86% and in plant dry weight index with 30, 69% compared to control with nematodes showed the most positive effect. Also, the treatments (with and without nematode - B. amyloliquefaciens) in plant height with 14, 17, in root length with 5/76, 22, in plant fresh weight with 29, 36, in plant dry weight index with 23, 26 percent compared to control with nematodes showed a positive effect. The number of galls in one gram of root, the number of eggs in one gram of root of the treatment containing the bacteria Curtobacterium sp. 84%, 15%, and 70%, respectively, and B. amyloliquefaciens respectively showed 73%, 5/9%, and 66% control compared to the control.
