The weed coenosis was formed mainly due to spring weeds, in particular: 42.3–84.7% of gray mouse, 0.6–12.9% of black nightshade, 5.7–30.3% of white quinoa, 2.2–12.2% of pepper mustard, others up to 3.2%. On average, by crop rotation, the weediness of one field in the control without fertilizers after plowing amounted to 83 pcs./m2 in the grain-grass crop rotation; 59 units/m2 in row crop rotation, and under intensive technologies 59/44 units/m2, respectively, or 29–25% less. With no-shelf treatments, the number of weeds on the background without fertilizers was 148/133 pcs./m2, and with a double dose of fertilizers it decreased to 126-104 pcs./m2, or by 14.8-22.0%. When using plowless tillage methods in five-field crop rotations of the grain-fodder-fodder type, it was established that during plowing, the clogging of crops is lower than during tillage by an average of 1.8–3.0 times, in particular, in winter wheat crops by 1.5–2.4 times, barley by 3.6–4.7 times, peas 2.3–2.6, grass – 1.8–2.1, sunflower – 1.2–2.0, corn – 1.4–4.7 times. A system of measures to control segetal vegetation in agrocenoses of various rotational crop rotations of the Left Bank Forest Steppe has been developed, which provides for integrated protection of crops. Agrotechnical measures included the observance of crop rotations, the use of various methods of soil cultivation (shelf, no-shelf, flat-cut), observance of sowing dates and sowing norms. The chemical method involved the use of herbicides according to the "List of pesticides..." and compliance with the regulations for their use. Product Description popup.authors Svitlana A.
