Experiments for determination of the effectiveness of product Neem Azal T/S (a. i. azadirachtin) were conducted at a concentration of 0,3% against some major pests in vegetable crops grown in greenhouses at the Maritsa Vegetable Crops research Institute, Plovdiv during the period 2010-2016. It was established very good insecticidal and acaricidal action of phytopesticide against: cotton aphid (Aphis gossypii Glov.); green peach aphid (Myzus persicae Sulz.); western flower trips (Frankliniella occidentalis Perg.); cotton bollworm (Helicoverpa armigera Hubn.); tomato borer (Tuta absoluta Meyrick) and two-spotted spider mite (Tetranichus urticae Koch.). This product is a successful alternative to using chemical insecticides and acaricides.

Key words: effectiveness, phytopesticide, pests, vegetable crops
