THE EFFECTIVENESS OF THE BIOLOGICAL METHOD IN THE PRODUCTION OF CUCUMBER IN GREENHOUSE CONDITIONS

Abstract

The specificity of the development of phytopathogens causing root rot in cucumber hybrids Athlete F1, Casanova F1 in block glass greenhouses of the 4th light zone was studied. The composition of the microflora of pathogenic cucumber fungi in protected ground was revealed and it was found that the dominant species are Pythium debaryanum Hesse, P. Ultimum, Fusarium culmorum (W. G. Sm.) Sacc., F. solani App. et Wr., F. gibbosum App. et Wr., F. oxysporum Schlecht, Ascochyta cucumis Fautr. et Room. The biological effectiveness of the cucumber protection biomethod using Planriz, Baktofit, Trichodermin preparations from root rot was evaluated, which amounted to 46.15-82.05%.
