During the implementation of the project on the 1st stage, the effects of microbial origin biostimulants contained avermectin (Avercom and Avercom-Nova) in 25, 50, 75 and 100 μl/L concentrations on the growth and development of tomato and wheat plants in in vivo and in vitro conditions were investigated. It was found that biostimulants Avercom and Avercom-Nova at 25 μl/L concentration supplemented to the nutrient medium improve the morphometric parameters (length of shoots and roots, plant weight) of two tomato varieties (Money Maker and Lagidnyi) in vitro compared to the control. The same data was obtained for wheat variety Zimoyarka. The data on studying the effect of Avercom and Avercom-Nova in vivo showed that the most effective concentration for tomato plants was f 25 μl/L, and for wheat - 100 μl/L. For screening and identification of Streptomyces strains producing an avermectin on high level, 9 soil samples were picked up in five different regions of Ukraine. As a result of the conducted researches a number of morphotypes of actinomycetes which belong to the certain morphotype were identified. Pure bacterial cultures of each of the actinomycete morphotypes were also obtained and avermectin accumulation was determined. Microorganisms-pathogens of plants which can be used as model in the further work on the project are allocated.
