Влияние экологически безопасных препаратов на распространенность болезней и урожайность картофеля

In a field experiment at the station "Holbuya" Yakut Scientific Research Institute of Agriculture during 2007-2009 years the effect of pre-soaking potatoes in biological product of local strain of Bacillus Subtilis at different doses was experomented: 1 billion CFU, 5 billion CFU (exposure 30 min), 1 billion CFU (exposure 60 min.) biologic product Fitosporin (Bashkortostan) was also based on the bacterial culture of B. Subtilis had been applied according to the instructions at the dose of 60 ml/ liter of water (exposure 30 min ). The studies for pre-processing of potatoes found the optimum dose of the drug B. subtilis 1 billion CFU in 60 minutes of exposure. There was a decrease in the prevalence of fungal diseases by 2.2%, bacterial diseases were not found in all the years of research, the average yield increase was 8.3 t / ha. Good effect was marked at the use of the drug Fitosporin: the prevalence of fungal diseases has decreased by 2%, bacterial was not found, yield increase 10.7%.
