Abstract
The influence of Siberian strains of
Bacillus spp. on the causing agent of grey mold of strawberry (the fungus
Botrytis cinerea Pers ex Fr.) and the host plant’s resistance to the disease were studied during three seasons with different weather conditions. The bacterial strains
B. subtilis, B. amyloliquefaciens and
B. licheniformis suppressed the
B. cinerea fungus
in vitro and
in vivo. In addition to the antifungal action, the bacterial strains positively influenced the strawberry plant growth. These results showed that the Siberian strains of
Bacillus spp. revealed polyfunctional properties towards strawberry plants infected with
B. cinerea.
