Abstract:
Nine strains belonging to the Bacillus genus have been isolated from soil samples in Tien Phuoc district, Quang Nam province. They were capable of surviving at 42°C, and the Bl, B4, B7 and B9 strains could produce toxic crystals at this temperature. B7 had the most promising characteristics in terms of spore-forming ability. The result of the 16S rRNA gene sequencing showed that B7 belongs to the Bacillus thuringiensis species, which is known to effectively control root-knot Meloidogyne sp. nematodes attacking pepper tree. This study was aimed at evaluating the inhibitory effect of the bacterial isolate under study on root-knot eggs and juveniles. It was shown that the highest inhibitory activity of the cultures of the bacterial strains under study was observed at their concentration of 109cells/mL; in this case, up to 89.67% of nematode eggs and 100% of juveniles J2 were killed after 10 h of treatment.
