Research results of studies of the terms of application of different fungicides (vintsint, benlat, impact, tilt) and their mixtures (bellat + impact, benlat + tilt, impact +tilt, benlat+ impact + tilt) for winter wheat (Triticum aestivum L.) crops, their biological efficiency against smut, root rot, rust, powdery mildew, fusarium blight and other diseases and determination of efficiency of economic expediency of application of 2-3 time wheat treatment with fungicides were presented. Research results showed that impact (0,5 l/ha) and tilt (0,5 l/ha) fungicides and their mixtures with benlat (0,5 l/ha) were effective against wheat fungi and promoted seed yield increase on 10,7-12,7 c/ha and were economically profitable in case of single application. Application of impact and tilt on 10-14 day promoted the duration of vegetation development of leaf, stem and head. Over three years the weight of one head after fungicides application was 1,52-1,73 g, weight of 1000 grains after application of impact was 37,8 g, after impact + tilt application – 41,2 g
