The main trend of modern crop production is the expansion of the use of plant
protection solutions and technologies, that ensure not only effective management of the number
of populations of harmful organisms, but also the production of environmentally safe agricultural
products with minimal anthropogenic impact on agro-ecosystems. One of our priorities is to
develop new environmentally sound polyfunctional biopreparations, that combine useful
properties of microbial strains such as phytopathogen antagonists and chitosan compositions that
increase disease resistance. The introscopic analysis of the seed material quality realized with the
non–destructive express techniques application was used for evaluation the effectiveness of the
compositions' complex influence on plants. The research studies the effectiveness of the influence
of Bacillus subtilis strains and chitosan compositions, including their combined effect, on soft
wheat productivity and its damage by disease agents. Data on the quality assessment of the grain
using microfocus x-ray radiography and gas-discharge visualization (electrophotography) are
also provided. The complex of more than 20 structural elements of wheat productivity was
analysed during the research. Assessment of the plant damage intensity according to the standard
criterion – the disease development, and additional phytopathological indicators was carried out.
The evaluation of the grains’ introscopic characteristics was carried out by the microfocus x-ray
radiography techniques combined with the digital x-ray image analysis. It is shown that the
biopreparation complexes, containing B. subtilis strains and Chitosan, have a combined
biological activity manifested in the optimization of wheat plants’ physiological state, increasing
productivity, diseases resistance.
