Abstract
Bacillus subtilis strain B2g was isolated from the rhizosphere of oilseed r ape (Brassica napus L, spp. oleifera Metzg. Sinsk.). The isolate was select ed with regard to plant growth-promoting and antifungal activities. Differe nt variants of formulation and application of Bacillus subtilis B2g (seed t reatment, treatment of soil with B2g-containing water-dispersable granules or soil treatment with a spore suspension) were examined for their effect o n plans growth and health in greenhouse tests. Plant growth-stimulating and antifungal effects were shown irrespective of the kind of application. Iso late B2g caused significant increases of plant growth of different cultivat ed and ornamental plants, i.e., sunflower, cabbage and cucumber. An effecti ve biological control was observed against different phytopathogenic fungi. The number of Fusarium oxysporum-damaged cabbage plants was reduced after a direct application of a B2g-spore suspension to the planting site. A soil treatment with water dispersable granules or spore suspension and a seed t reatment caused increases of emergence rates in Rhizoctonia solani- and Fus arium oxysporum-inoculated variants of cabbage.
