Application of metabolites and extracts of fungi for tomato disease resistance induction and growth stimulation

Plant resistance to biotic and abiotic factors is determined by a complex of specific and non-specific immune responses. The aim of the work is to investigate the properties of some saprotrophic and phytopathogenic fungi as inductors of plant resistance. Research conducted in 2005-2018 at the Department of Botany of the Belarusian State University. The article presents the results of the influence of metabolites of the culture fluid (QL) of micro- and macromycetes, aqueous extracts, and also fungicides based on strobilurins on disease resistance and yield of tomato. Soaking seeds led to an increase in early ripeness, productivity when processing QL of Fusarium oxysporum by 19%, to an increase in the share of healthy fruits in the yield structure by 20.7%; when treating QL and extracts of Lentines edodes (shiitake) and Ganoderma lucidum (lacquered tinder, Reishi), strobi and quadris preparations to increase yields by 35-75%, the proportion of healthy fruits in the yield structure by 4.8-14.3%. Thus, the use of metabolic products of Fusarium oxysporum f. lycopersici, Lentines edodes (shiitake) and Ganoderma lucidum, as well as aqueous extracts of these basidiomycetes as inducers of resistance and plant growth stimulants have an undeniable perspective.
