A. V. YA. YURYEV NATIONAL ACADEMY OF AGRАRIAN SCIENCES OF UKRAINE popup.description2 Study Object - weeds, response of crops and weeds to herbicides. Study Purpose - to determine weediness of fields under the currnet land use and to develop effective energy-saving and environmentally friendly methods of weed control in field crops. Study Methods - expeditionary, field, laboratory. Patterns of transformation of the segetal component of field agrophytocenoses under the influence of anthropogenic factors and drought were determined. For the first time, unusual for the zone weeds - China jute and trailing hollyhock - were identified in field crops. A predictive model of weed-induced yield losses in grain corn crops was developed, a similar model was rationalized for pea, chickpea and soybean. A greater level of competitiveness of weeds in chickpea as compared to soybean and pea, and in soybean as compared to grain corn was observed. The most effective soil and post-emergence herbicides and their combinations in crops of grain corn, soybean and chickpea were suggested. Soybean tolerance to modern herbicides was evaluated. The effects of combination of herbicides with growth regulators and microfertilizers on weeds, nitrogen-fixing nodules, soybean yield capacity and seed quality were described. Five methods of protection of grain corn and soybean crops against weeds, which were confirmed by utility model patents (No 56 632, No 67885, No 67 886, No 67929, No 87236), were developed. Six guidelines, which are used in the training process and research of scientists from higher educational institutions, in agricultural enterprises of all forms of ownership, by specialists of the State Phytosanitary Inspection Service.
