“…Для обприскування посівів завжди застосовують гербіциди, які передбачені "Переліком пестицидів і агрохімікатів, дозволених до використання в Україні". Препарати і норми їх витрат здебільшого підбирають з урахуванням видового складу і чисельності бур'янів (Ivashchenko, 2001;Matyukha et al, 2008;Tkalich et al, 2018;Tsyliuryk et al, 2017;De Cauwer, 2010;Harker & OʺDonovan, 2013;Matyukha et al, 2005;Tsykov, 2014).…”

The results of research on the effectiveness of action of herbicides on weeds incrops of Scarlet grosbeak of the Linza variety, conducted on the experimental field of the educationaland research center of the Dnipro State Agrarian and Economic University, located inthe Dniprovskyi district of Dnipropetrovsk region are presented. The soil is represented by chernozemordinary low in humus full-profile. The potential soil contamination in the arable layer byvegetative organs of reproduction of perennial suckering weeds was average (100–120 thousandpieces / m2), and high (800–900 million pieces / ha) by seeds of annual weeds. Scarlet grosbeakwas placed after winter wheat. Soil-applied and post-emergence herbicides were applied in therecommended time by a small-sized sprayer OM-4, developed by the Department of GeneralAgriculture and Soil Science of the State Agrarian and Economic University and limited liabilitycompany “Agromodul”. Years of Scarlet grosbeak growing were characterized as typical for theSteppe zone of Ukraine, but differed in the amount of precipitations. The main reasons for thesmall area of distribution of Scarlet grosbeak are identified. The attention was paid to the needfor integrated weed control for the successful growing of this legume crop. It is found that in thesegetal сommunity of Scarlet grosbeak the dominant position was occupied by common ragweedand annual cereals, which at the beginning and end of the growing season accounted for about90% of the total number of weeds. The presence of a small amount of white orache, lesser bindweed,redroot amaranth and others was also noted. In accordance with the evaluations of the technicalefficacy of herbicides in crops of Scarlet grosbeak, which are a weak competitor to weeds,indicate the need to take into account their effect on the weight of weeds. The best results in thecontrol of common ragweed in the crops of the studied culture were provided by preparationsbased on Prometryn 400 g / l + Metribuzin 100 g / l, Imazethapyr 100 g / l and Imazamox 40 g / l,which helped to reduce its weight in the air-dry state by 67.9; 64.4 and 62.1%, respectively, comparedwith the control. The least effective was the insurance (post-emergence) herbicide based onMetribuzin 600 g / l, which helped to reduce the mass of common ragweed in the air-dry state byonly 10.7% compared to the control. The technical efficiency of herbicides action and their tankmixtures on dicotyledonous annual weeds was almost the same and ranged from 50.0% to 87.5%.The use of herbicides and their tank mixtures in general allowed to save from 0.03 t / ha to 0.26 t/ ha grain of Scarlet grosbeak compared to the control without herbicides. Herbicide preparationsdiffered insignificantly in terms of the effect on grain yield. The insurance (post-emegence) herbicidesbased on Imazamox 40 g / l and Imazethapyr 100 g / l should be distinguished. The use ofthis herbicides provided yielding capacity on the level 1.19 and 1.23 t / ha, which was more thancontrol by 22.7 and 26.8%, respectively.

“…Global warming may be one of the reasons for the decline in yields of many field crops (Schroetter, 2013). Weeds are an additional factor that limits the increase in grain productivity (Tsyliuryk et al, 2017(Tsyliuryk et al, , 2018Tkalich et al, 2020). Grain sorghum is characterized by high yielding capacity and drought resistance.…”

The highest control of ragweed (Ambrosia artemisiifolia L.) in the field experiments was provided by the herbicide Primekstra TZ Gold (effect - 83%; dose - 4.5 l/ha), bent sedum (Amaranthus retroflexus L.) with herbicide Mastak (effect - 88%; dose - 0.5 l/ha), chicken millet (Echinochloa crus-galli L.) using the herbicides Varyag and Datonit Gold (effect - 57%, dose - 4.5 and 2.5, respectively), white quinoa (Chenopodium album L.) – herbicide Datonite Gold with surfactant (effect - 85%; dose - 2.5 l/ha). The greatest chemical control was provided by the application options of herbicides Varyag – 4.5 l/ha and Agent – 0.6 l/ha in the phase of 3-5 leaves of the crop in June. This treatment provide the Ponki sorghum hybrid grain yield increase 24-27% compared to the control.

Goal. To establish the biological effectiveness of herbicides and their tank mixtures for the protection of winter wheat crops from weeds in the Steppe of Ukraine. Methods. General scientific, the main of which were: field; measuring and weighing; variance and correlation. The Institute of Grain Crops (IGC) of NAAS of Ukraine studied the biological effectiveness of herbicides against the background of non–steam precursors (stubble, oats, sunflower), the experimental scheme included 17 options for the use of drugs and their tank mixtures. Results. It is proved that the complete and 100% control of weeds is provided by the tank mixture of herbicide Dialin super — 0.8 l/ ha in combination with the growth regulator Gulliver stimulus — 500 ml/ ha, 21.1 pieces/ m² of weeds are destroyed here, with of which 16.8 pieces/ m² were root–sprout perennials (field birch (Convolvulus arvensis L.), pink field thistle (Cirsium arvense L.), Tatar milkweed (Lactuca tatarica L.)). The maximum grain yields were provided by the plots where the tank mixture of dialen super — 0.8 l/ ha + PPP Gulliver stimulus — 1.0 l/ ha — 6.4 t/ ha was applied; Dialin super — 0.8 l/ ha + PPP Gulliver stimulus — 1.5 l/ ha — 6.1 t/ ha and Dialin super — 0.8 l/ ha + PPP Peram — 200 ml/ ha — 6.0 t/ ha, this can be explained mainly by the low level of weediness of the field after treatment with drugs, namely the low biomass of weeds 1.0—3.1 g/ m² while in the control and application of growth regulators they were significantly greater and were 59.6 and 20.7 g/ m², respectively. Conclusions. Complete and 100% control of weeds provides a tank mixture of herbicide Dialin super — 0.8 l/ ha in combination with the growth regulator Gulliver stimulus — 1.0 l/ ha resulting in a maximum wheat yield — 6.4 t/ ha and quality indicators grains.
