In production researches, the biological efficiency of preparation Entolek based on a strain „Lecanicillium lecanii“ BL-2 is estimated. A significant inhibiting potential of the preparation for phytophages control in vegetable crops in greenhouses was determined: biological efficiency against the spider mite „Tetranychus urticae“ Koch. was 94.6%, against onion thrips „Thrips Tabali“ Lind. – 94.0%, against whitefly „Trialeurodes vaporariorum“ Westw. – 90.7%. The application of the preparation Entolek in tomato crop provided the yield increase by 7.5-31.8%, in cucumber crop – 5.0-14.8%. The application regulations of the preparation Entolek for pest control in greenhouse crops, based on the pest number control and biological pest peculiarities, are developed.
Buvo atlikti preparato “Entolek”, kurio pagrindas “Lecanicillium lecanii” štamas BL-2, efektyvumo tyrimai. Nustatytas žymus preperato slopinantis poveikis fitofagams, kenkiantiems daržovėms šiltnamiuose: biologinis aktyvumas prieš voratinklinę erkę (“Tetranychus urticae” Koch.) – 94,6 %; prieš svogūninį tripsą (“Thrips Tabali” Lind.) – 94,0 %; baltasparnį (“Trialeurodes vaporariorum” Westw.) – 90,7 %. Preperato “Entolek” panaudojimas pomidorų derlių padidino 7,5–31,8 %, agurkų – 5,0–14,8 %. Preparato “Entolek” veikimas šiltnamiuose auginamoms daržovėms apsaugoti pasireiškia kenkėjų skaičiaus sumažinimu ir poveikiu kenkėjų biologijai.
