Two strains of Bacillus subtilis (B-7-10 and B-5-10), isolated by us, were tested in comparison withthe producer strain of the biopreparation Gamair Bacillus subtilis M-22 (standard strain) for their ability tocontrol apple scab. The experimental variant included 4 trees, each being considered as one replication. Numberof observed leaves per replication – 100. Treatment dates were established based on tree state and weathercontitions. Six treatments were performed over the season. Cultural liquids (50%) of the tested spore-formingbacteria, by their action on scab pathogen, are not inferior to the standard culture. The culture B-7-10 showedsomewhat more biological efficiency (79,1%) against apple scab as compared to both standard culture (77,9%),and B-5-10 (69,8%). We consider to be promising further work with these strains for developing a technology forthe production of scab control preparations.
