aref2 Studies were carried out to investigate the effect of bacterial strains of the genus Bacillus on adaptation, growth, vegetative propagation, winter hardiness and fungal infection of strawberry plants. Field experiments were conducted in 2011-2014 in Novosibirsk region. The objects of the research were strawberry variety Junia Smayds; strawberry leaf spot; bacterial strains from All-Russia collections of industrial microorganisms (they are listed according to catalogue of this collection): B. subtilis V-10641, B. amyloliquefaciens V-10642, B. licheniformis V-10562, as well as a mixture of 3 strains - B. amyloliquefaciens V-10642, B. amyloliquefaciens V-10643, B. subtilis V-10641(Fitop 8.67). Plants were treated before planting by soaking of the root system in a working suspension containing biological agents in concentration 1*10E5 CFU/ml. Pre-planting treatment of the root system with B. amyloliquefaciens strain V-10642, B. subtilis V-10641, B. licheniformis V-10562 and Fitop 8.67 (the mixture of 3 strains) increased the survival ability of strawberry on 1519%, and as a result of immunizing action reduced the degree of damage by white spot 1.21.8 times. Processing by strains of B. amyloliquefaciens V-10642, B. subtilis V-10641 and Fitop 8.67 increased winter hardiness of plants, which reduced their death during the winter 1.92.2 times. The maximum effect in stimulating vegetative propagation was obtained by treating with B. amyloliquefaciens V-10642 and Fitop 8.67, the increase in the number of filial rosettes by 5359%. Strains of B. amyloliquefaciens V-10642, B. subtilis V-10641 and Fitop 8.67 had the most expressed multifunctional effect on plants, showed anti-stress, growth promoting and immunizing properties, which is promising for their use to improve efficiency and environmental stabilization of production of planting material of strawberry.
