Representatives of the genus Acremonium can cause diseases of plants of the familyCucurbitaceae, causing damage to agriculture. Application of Acremonium sp. 502 in the soil (creation ofan artificial infectious background – AIB) reduces the weight of the root system of plants by an averageof 13% and reduces the harvest of cucumbers by 41% compared with control. Inoculation of seeds withTriсhoderma viride 017 contributes to limiting the spread of acremiosis, the biological efficiency of thestrain is 61%. This is due to the death of seedlings of plants. The inoculation of seeds with T. viride 017provided for the formation of a more powerful root system and increased harvest by 34% (15.4 t/ha)compared with the variant containing the AIB. The present strain is a promising bioagent of a microbialpreparation for the protection of cucumber plants from acremiosis.
