Efficiency of the following herbicides for the chemical weeding of winter wheat (Triticum aestivum L.) seedings was analyzed: simazin (80% wetting powder), rejser (25% emulsion concentrate), stomp (33% emulsion concentrate), arelon (50% emulsion concentrate), satis (18% wetting powder), lentipur (70% suspension concentrate), lintur (65% wetting powder), arelon (50% suspension concentrate), trezor (60% wetting powder), mixture of simazin (80% wetting powder) + dialen-super (48% water solution). Research results showed that herbicides lintur (0,160 g/ha), lentipur (1,5 l/ha), stomp (5,0 l/ha), arelon (2,5 l/ha) and dialen-super (0,7 l/ha) provided yield increase on 7,9-10,5 c/ha and high recoupment level. Pregermination treatment with rejser (1,5 l/ha) and satis (0,150 l/ha) treatment at the stage of 2-4 leaves was the most economically feasible. Maximum yield (47,2 and 47,4 c/ha) over three years was obtained after application of stom and mixture of simazin and dialen-super which provided yield increase on 10,3 and 10,5 c/ha. Chemical weeding with lintur provided yield increase on 10,8 c/ha. Chemical weeding with arelon in autumn and spring provided yielding capacity of 45,3-45,5, with lentipur – 45,0-44,8 c/ha. Chemical treatment with trezor provided yield increase on 3,7 c/ha
