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.

Field Bindweed

The effect of various growth regulators on seedling field bindweed (Convolvulus arvensisL. # CONAR) growth and control with herbicides was evaluated. Fourteen growth regulators were applied at 0.38 to 380 g/ha 7 days before herbicide application in greenhouse, growth chamber and field studies. Field bindweed seedlings pretreated with growth regulators were more effectively controlled by herbicides compared to those not pretreated in greenhouse evaluations. Abscisic acid [[R-(Z,E)]-(+)-5-(1-hydroxy-2,6-6-trimethyl-4-oxo-2-cyclohexane-1-yl)-3-methyl-2,4-pentadicenoic acid] (ABA), ancymidol [a-cyclopropyl-a-(p-methoxyphenyl)-5-pyrimidine methanol], cycloheximide {3-[2-(3,5-dimethyl-2-oxocylohexyl)-2-hydroxyethyl]glutarimide}, ethylenediamine tetraacetic acid [N,N′-1,2-ethanediyl-bis-(N-(carboxymethyl) glycine] (EDTA), and 1-naphthaleneacetic acid (NAA) increased field bindweed stem length. Ancymidol and gibberellic acid [ent-3α,10,13-trihydroxy-20-norgibberell-1,16-diene-7,19-dioc acid 19,10-lactone] (GA) increased root weight, and GA increased root length. Cycloheximide, ethephon [(2-chloroethyl)phosphonic acid] and MH (1,2-dihydro-3,6-pyridazinedione) decreased field bindweed root weight. Ancymidol, GA and IAA (indole-3-acetic acid) increased the number of shoots per plant of seedling field bindweed. Dicamba (3,6-dichloro-2-methoxybenzoic acid) efficacy was enhanced following field bindweed preconditioning with ethephon and IAA. Ancymidol and cycloheximide applied as pretreatments increased glyphosate [N-(phosphonomethyl)glycine] activity on seedling field bindweed. Ancymidol and IAA pretreatment improved field bindweed control with triclopyr {[(3,5,6-trichloro-2-pyridinyl)oxy] acetic acid}. Herbicide-growth regulator combination treatments that increased field bindweed control in greenhouse and growth chamber studies did not increase top growth control in the field.

The Impact

In the formation of the winter wheat yield, the protection of the crop from pests, stress, pesticides and adverse abiotic factors is one of the important elements of the technology. To increase yield and reduce the impact of adverse factors in winter wheat protection systems, plant growth regulators are used. In the conditions of the Ryazan region in 2019-2020, the effectiveness of the use of tank mixtures of pesticides with the growth regulator Energia-M (0.01 kg/ha) in the protection systems of winter wheat of the Danaya variety was studied. In the variant with the use of a tank mixture of pesticides with a growth regulator, a statistically significant excess of yield was noted in comparison with the control (without treatment) by 1.4 t/ha (31 %) and with the variant with treatment using a tank mixture without the use of a growth regulator - by 0.9 t/ha (18 %). Under the influence of the plant growth regulator, a decrease in the negative impact of pesticides on growth processes, an increase in crop yield by 18 % due to the formation of an additional number of productive stems (80 pcs / m2 ) were noted and a higher net operating profit was obtained compared to the protection system without a plant growth regulator.

Metathesis Reaction

AbstractPlant growth regulator — 2-chloroethyltrimethylammonium chloride (CCC) was converted into ionic liquid in the metathesis reaction. New forms of CCC as ILs were stable in air as well in contact with water and organic solvents. The biological action of the cation (CCC) in ILs was preserved. Type of anion determined hydrophobicity and hydrophilicity of the whole molecule and it also influenced the biological activity of the plant growth regulator. All of the investigated salts retarded growth of winter wheat stems and most of them increased yield at the same time, when compared to control and standard 2-chloroethyltrimethylammonium chloride.

The Uk

The use of plant growth regulators (PGRs) on winter wheat in the UK is a common practice. Significant yield benefits can be gained from its use. For the most efficient use of PGRs the rates of application must be matched to the crop canopy. The variation of crop growth was monitored during the spring growing season using vegetation indices derived from satellite imagery. Application rates of PGRs were matched to changes in biomass as measured by the imagery. Final yields were measured using a GPS combine yield meter. The variable application showed an average yield benefit of 0.4 t/ha over the uniform full recommended application rate.

The article presents the results of a multi-year research aimed at establishing the influence of plant growth regulators and doses of nitrogen top dressings on the growth, development, productivity and technological qualities of Grom variety of soft winter wheat grain of the FSBSI «SGC named after P.P. Lukyanenko» selection. The results of the research revealed that the duration of the entire growing season and interphase stages of winter wheat development was largely influenced by weather conditions in the spring-summer period. Application of nitrogen top dressing in the «tillering-beginning of stemming» phase promoted the formation of more vigorous winter wheat plants with an increased tillering coefficient. The best indicators were obtained in options where «Biosil» preparation was used. The most intensive increase in the aboveground mass of winter wheat throughout the growing season occurred with the use of the «Alfastim» growth regulator; it was followed by «Novosil» preparation. The cultivation of crops with growth regulators increased the productive plant stand by 7,8–15,2%, but didn’t have a significant effect on the other elements of the crop structure. Application of nitrogen fertilizer in doses of N35+N35 иN35+N35+N20 when treated with «Novosil» growth regulator provided a high yield – up to 7,13 t/ha. Slightly lower was the yield with the use of «Alfastim» preparation compared with «Novosil». In the option without nitrogen fertilizers the fifth class grain was formed, and the treatment of winter wheat crops with the studied preparations increased the class of grain to the fourth one, due to an increase in the content of protein and gluten in the grain. Similar changes were also noted when nitrogen was added to the top dressing at doses of N20 + N20 and N35 + N35. Spring nitrogen fertilization of winter wheat crops in the heading phase contributed to an increase in the grain class.

Aim. A study of the effects of growth regulators derived from natural raw materials on the photosynthetic apparatus surface and the yield of winter wheat. Methods. Morphometric, spectrophotometric, statistical. Results. An increase in the value of canopy chlorophyll index (ChlI) of Smuhlianka and Astarta varieties under the treatment of plants with Stimpo growth stimulator was established at anthesis, a positive effect of the regulator Regoplant – only for Smuhlianka variety at milk-wax ripeness. Chlorophyll photosynthetic potential (ChlP) during the period anthesis – milk-wax ripeness increased significantly under the use of growth regulators in both varieties, while the efficiency of treatments had varietal differences: growth was greater (11–18% compared to control) in the variety Smuhlianka than in the variety Astarta (6–7%). A positive correlation was established between the yield and ChlP during the period anthesis – milk-wax ripeness. Under the action of treatment of plants with growth regulators, the increase in grain yield was significant (0.29–0.45 t/ha) only in the variety Smuhlianka. Conclusions. The positive effect of treatments of plants with growth regulators, obtained from natural raw materials, on the value of canopy ChlI at anthesis and ChlP during period anthesis – milk-wax ripeness was established. A positive correlation between the winter wheat yield and ChlP during the period anthesis – milk-wax ripeness was found. Varietal differences in the effect of growth regulators treatment of plants on ChlP and yield were found.

Research objective is improving the grain yield of wheat by reducing of winter and spring wheat cropsweedines. The studies were carried out on experimental fields of the Povolzsje Science Research Institute of selection and seeds production of P. N. Konstantinov. Volga region Scientifical-research Institute of Selection and Seed growing named after P. N. Konstantinov in 2012-2014. The main purpose of researches was to study influence of weeds for grain yield components in winter and spring wheat. The evaluation of the abundance of weeds was performed by the method of Drude. Under the influence of weed, productivity of land winter wheat decreased by 3-26%, spring wheat decreased by 17-33%. The most harmful for winter wheat turned out creeping-rooted weeds: Cirsium arvense, Convolvulus arvensis, of young weeds dominated Cánnabis ruderális, and wintering weed: Lactuca serriola, Thlaspi arvense. In the spring wheat was dominated weeds of creeping-rooted form: Convolvulus arvensis, Cirsium arvense, Sónchus arvénsis and Euphorbia virgata. Winter wheat is less exposed to weeds than spring wheat. Yield depression was mainly due to decrease the number of productive stems and dry wheat mass. Also on the harmfulness of weeds is influenced by the weather conditions of the year. For winter wheat during the wet and warm autumn dominated wintering weed: Thlaspi arvense, Lactuca serriola. In years with dry weather conditions creeping-rooted weeds prevail For spring wheat during the wet spring it is dominated the spring weeds in dry years the most harmful creeping-rooted weeds. For the harmfulness of weeds the density of the crop also affect. When sparse crops of weeds more harmful than at the optimum plant density. Infestation weeds adversely for the yield of both winter wheat and spring wheat.
