Purpose -to develop theoretical principles and to ensure a reliable protection of field crops against pests in Eastern Forest-Steppe of Ukraine. Methods - field and laboratory. Results - Theoretical basics have been developed, and protection of field crops against harmful organisms upon climatic changes in this zone is provided. Dicotyledonous perennials are the most harmful weeds in late-sown winter bread wheat. Weediness was minimal when wheat was sown after soybean. The following variants gave increased yields: late-sown winter bread wheat - Granstar Gold 75, 30 g/ha + Vermyiodis, 6.0 L/ha during the tillering phase (+0.69 t/ha); grain corn - Task Extra 66.5, 440 g/ha (+2.72 t/ha); pea - Pulsar 40, 1.0 L/ha (+0.21 t/ha); chickpea - Teaser, 2.0 L/ha + Panda, 3.5 L/ha (+0.19 t/ha); soybean - Teaser, 2.0 L/ha + Selephit Extra, 2.0 L/ha prior to germination (+0.40 t/ha) and Tabezon, 1.5 L/ha + Commander, 0.4 L/ha (on primordial leaves) + Lemur, 1.5 L/ha (2–3 ternate leaves) (+0.36 t/ha). The maximum preserved grain yield and profitability were achieved via complex application of fertilizers and pre-sowing treatment of winter bread wheat seeds with dressers Scenik (1.15 t/ha and 42%) and Cruiser 350 FS (+1.05 t/ha or 67%); of spring barley seeds with Cruiser 350 FS (+2.16 t/ha or 52%). Scientific results have been tested and implemented: "The system of protection of cereals against diseases and pests in the Eastern Forest-Steppe of Ukraine" on 54.4 ha, "Optimized elements of crop protection against weeds in field cultivation technologies" on 133.9 ha, "Protection system of cereals and grain legumes against pests" on 164.0 ha, " Protection System of pea, chickpea and soybean crops against weeds "on 26.0 ha. Recommended for use in production and research. Product Description popup.authors Hlubokyi Oleksandr M. Hutianskyi Roman A. popup.nrat_date 2021-03-17 Close
