Pot experiments in vegetation period under greenhouse conditions have been performed during the period 2008-2010 for determination of the effectiveness of bioproducts Agri 50 NF 2 ppm and Agricolle 3 ppm on powedery mildew (Sphaerotheca fuliginea Pollaci), cotton aphid (Aphis gossypii Glov.) and greenhouse whitefly (Trialeurodes vaporariorum Westw.) in cucumbers variety Salvo and Mirey. Very good biological activity of the products was established on the greenhouse whitefly adults at 7 th day after treatment (respectively E=88,71% and E=99,03%) and good activity against cotton leaf aphid treated with Agri 50 NF 2 ppm (E=67,87%). Good effectiveness on powdery mildew in cucumbers was recorded for the product Agricolle 3 ppm – 68,02%.
