OPTIMIZATION OF THE SYSTEM OF IRRIGATED WINTER WHEAT PROTECTION AGAINST HARMFUL ORGANISMS IN SOUTHERN UKRAINE
Journal Title: Біоресурси і природокористування [Biological Resources and Nature Management] - Year 2018, Vol 10, Issue 5
Abstract
The research findings show that the highest effectiveness in irrigated winter wheat protection against harmful organisms is provided with the application of seed disinfectant Serticor 050 FS (1 l/t), fungicide Alto Super 330 EC, emulsion concentrate, together with herbicide Peak 75% water-soluble granules (0.45 l/ha + 0.020 kg/ha) in the stem elongation phase, as well as fungicide Amistar Extra 280 SC suspension concentrate (0.5 l/ha) at the beginning of flowering, and insecticide Enzhio, 24.7% suspension concentrate (0.18 l/ha) at the beginning of milky ripeness of grain. The study determined that Konka variety had a seed yield of 3.59 t/ha, which is 8.2% more than in Khersonska 99. The combined application of biopreparations Trichodermin and Gaupsin proved to be the most effective. Avatar had an advantage over other micronutrients under study and allowed gaining a 7.3-14.2% seed yield increase. Dispersion analysis confirms that microfertilizers take up the greatest proportion (58.2%) in the impact on the formation of winter wheat yield. The effect of varietal composition (20.0%) and plant protection (16.1%) was also high.
