The role of Trichoderma and Gliocladium fungi in the soil biocenosis of greenhouse cucumbers

The analysis was conducted on the general biogenicity and phylogenetic structure of fungi in soil microbiome greenhouse cucumbers grown as a monoculture after precursors pepper lettuce. relationship between following indicators has been proved: total biological activity soil, species composition micromycetes, development Fusarium root rot, yield. effect preparations based strains Trichoderma viride Gliocladium virens antagonistic nematodes yield studied. results experiment show that when are precursor lettuce, rot does not exceed critical values. introduction into form dry preparation with titre 2.0 x 1010 conidia/g transplanting plants to permanent place at consumption rate 40 kg/ha increases by 20-23%. is part study "soil exhaustion" syndrome possibilities overcoming it. obtained will serve bioindicators can be used for preliminary diagnostics sanitary condition degraded soils, selection agrotechnical, breeding protective measures plants.
