ENDO-FORMING BACTERIA BACILLUS THURINGIENSIS VAR. THURINGIENSIS AS A BASIS OF MICROBIAL PREPARATIONS OF A WIDE SPECTRUM OF ACTION
Journal Title: Scientific journal «Biological Systems: Theory and Innovation» - Year 2017, Vol 2, Issue 270
Abstract
The aspects of using microbial preparations based on Bacillus thuringiensis for the plants protection against harmful organisms was discussed. The efficacy of the Bacillus thuringiensis 87/3 strain was demonstrated in laboratory and field conditions using Leptinotarsa decemlineata Say.(larvae of younger age, L 1-2 ), as well as phytopathogenic micromycetes Venturia ssp. It has been established the high adaptability of t B. thuringiensis 87/3 strain (the titre of the metabolic spore-crystalline complex is from 3.6 to 4.8 billion/ml.), entomocidal (99.4%) and antifungal effect, which is shown in reduction of the diseased plants number by the apple scab causative in 1,5-2 times, in comparison with the control variant. A wide range action of endo- forming bacteria Bt demonstrates the prospects of their use for phytoprotection.
