The invention relates to biotechnology and agricultural Microbiology, in particular for complex biological activities for crop production, and can be used for presowing treatment of seeds of agricultural crops, spraying of plants in the growing season, when preparing agricultural products for storage, for soil prior to planting and during the growing season of plants in the conditions of healthy soil and agro-ecosystem, and in terms of soil contamination with residual quantities of fungicides, herbicides, insecticides, phytopathogenic micromycetes and products of their metabolism.
Currently for agriculture known bacterial preparations on the basis of one culture of microorganisms, which either inhibit the development of pathogenic fungi and bacteria, or stimulate the growth and development of plants, or contribute to the fixation of atmospheric nitrogen or transfer of insoluble soil phosphates into soluble forms.
Known drug backoff based on Bacillus subtilis strain IPM-215 [RF Patent №2019966, IPC A01N 63/00, publ. 1994]. The disadvantages of BackOffice are limited scope, lack of accessible sources of information about health-improving effect on plants in bacterial defeat, effective, protective effect against diseases in terms of what s open ground and the capacity for nitrogen fixation and phosphatability. In addition, the composition of the drug, with many components to it, the technology for preparation of multi-stage and complex.
Known drug on the basis of Azotobacter chroococcum BH-1811 [RF Patent №2289620, IPC C12N 1/20, A01N 63/00, C12R 1/065, publ. 2006], designed to increase crop yields and improve their resistance to various diseases. The disadvantage of the drug is low effectiveness against fungal and bacterial pathogens of agricultural crops and the lack of ability to phosphatability.
There are also biological products on the basis of the Association of microorganisms of different taxonomic affiliation.
Known drug to stimulate growth and protect plants from disease - Extrogen [RF Patent №2302114, IPC A01N 63/00, C12N 1/20, C12R 1/065, C12R 1/07, publ. 2007], which contains strains of Bacillus mycoides var. B.A. ARRIAM No. D and Azotobacter vinelandii var. NP ARRIAM No. D. Known biological product for autumn, spring and summer soil, root and basal fertilizing during the growing season of plants, as well as pre-sowing treatment of seeds, which are a mixture of suspensions thirteen different strains [RF Patent №2322061, IPC A01N 63/00, C12N 1/20, publ. 2008]: Agrobacterium tumefaciens (B-4116, Agrobacterium radiobacter B-956, Azotobacter chroococcum B-2375, Bacillus thuringiensis B-2918, Bacillus subtilis B-6554, Bacillus subtilis B-4419, B. megaterium Bacillus B-4440, B. megaterium Bacillus B-200, Bradyrhizobium japonicum B-1978, Erwinia ananas B-5292,Lactobacillus casei B-3961, Pseudomonas fluorescens B-l138, Rhodopseudomonas palustris B-1620.
