Abstract

Products of microbial origin in combined with para-aminobenzoic acid (pABA) derivatives, can be the basis for organic farming and plant resistance to unfavorable environmental factors inducing, as well as for the crop yield increase. The article presents the results of the study of the efficiency of fruit-cultures and potato plantations treatment with aqueous suspensions of entomopathogenic bacteria Bacillus thuringiensis subsp. kurstaki and Bacillus thuringiensis var. thuringiensis with addition of para-aminobenzoic acid derivatives solutions in concentrations 10-2, 10-4, 10-6 mM.. The results demonstrate the possibility of using entomopathogenic bacteria in a tank mixture with pABA to create biological preparations as alternatives to pesticides and the development of biological methods of plant protection.
