Research results of studies of the comparative efficiency of some perspective postemergence herbicides (titus, bazis, kallisto, sekator turbo) in maize seedings in the concrete agroclimatic conditions taking into consideration the species composition of weed flora were presented. Influence of studied herbicides on the dominating species of weed plant (Matricaria inodora, Viola arvensis, Stellaria media, Agropyron repens, Galeopsis tetrahit, Chenopodium album, Capsella bursa pastoris, Polygonum persicaria) was studied. Variants with application of sekator turbo (0,09 g/l) and bazis (25 g/ha) herbicides showed high biological efficiency (95,5% and 94,6% accordingly) against weeds invasion in the conditions of annual bilobate type of maize seedings. Applied herbicides made it possible to achieve high and positive yield response of maize herbage. The highest maize herbage (226,4 c/ha) was after application of sekator turbo herbicide. Sekator turbo herbicide provided the highest (557,5 c/ha) yield and quantity of plants in different phases of ripening. The following different action of studied herbicides of plant ripening was revealed: titus and sekator turbo herbicides lowered plant development; kallisto exercised the stimulating effect and provided growing of 72% of plant at the phase gold ripeness and the highest content of dry mass in the yield (32,1%)
