IMPACT OF HERBICIDES AND DATES OF THEIR APPLICATION ON WEED INFESTATION AND YIELD OF WINTER WHEAT
The article presents the results of the research on herbicides application to winter wheat plants. It’s established that under the existing conditions the herbicides Alister Grande, OD (0.75 L/ha) and Complete Forte, SC (0.5 L/ha) ensure the greatest destruction of weeds when applied at the autumn tillering stage of the crop. In this case the number of weeds reduces by 99.4 % and 98.5 % respectively and their wet weight - by 99.9 % and 99.8 %. This provides the greatest increase of winter wheat yield (39.2 %). The application of the studied herbicides before winter wheat sprouting promotes the yield increase by 22.2-26.7 %, at the 2-leaf stage - by 31.1-34.4 %, and at the spring tillering stage - by 27.3-30.1 %.
