Wild mustard (Sinapis arvensis L.) is a weed that frequently infests spring wheat (Triticum aestivum L.) fields in Moscow province, Russia. It is an annual broad leaf weed, which is indigenous throughout most parts of the globe and one of the most competitive weeds of spring cereal crops. In southern Russia it is emerging as an important crop competitor. Field trials focusing on herbicide timing and efficacy on wild mustard control and spring wheat yield in the Moscow region, Kashira and Baribino districts. A PRE glyphosate application to wheat regardless of fall or spring application timing favorably suppressed wild mustard in 2018. Weeds were not controlled in 2019 with the earliest application timings of glyphosate because weeds emerged late. In comparing fall and spring application timings, the formulated combination of (iodosulfuron/mesosulfuron/antidote mefenpyr-diethyl) at both field rates provided 80% weed control for all application timings and locations, and also resulting in the greatest spring wheat grain yield. Overall, herbicide treatments performed greater when they were in the fall than during the spring. Based on POST herbicide application, tribenuron-methyl provided the greatest wild mustard suppression (75%) and also caused the highest reduction in wild mustard biomass (3.3 g), stem number (6), seed number (880) and germination percentage (33%). When wild mustard was approximately 32 weeds/m2 causedtotal wheat yield loss.

Abstract To study the effect of sodium Selenite application different methods on the yield of spring wheat varieties, depending on the conditions of water supply, a series of vegetation experiments in accordance with the methodology were carried out. The object of the study is spring wheat of the Zlata variety (Triticum aestivum L.). It was found that the effect of selenium on the yield of wheat of the Zlata variety depended on the method of its application and the conditions of water supply. With optimal water supply, the positive effect of selenium on the yield of spring wheat plants was revealed with both methods of applying sodium selenite. It was found that in conditions of drought, the positive effect of selenium was obtained with both methods of using sodium selenite. The greatest efficiency of selenium is obtained in foliar processing of plants. The increase in grain weight in this variant was 1.4 times. The increase in the share of the agronomic significant part of the wheat crop yield to 36% is shown, which indicates the decrease in the negative effect of drought on the formation of spring wheat yield when using foliar processing of plants.

Triallate granules were applied at 2.8 kg/ha without incorporation either immediately before or after planting into standing spring wheat (Triticum aestivum L. ’Fielder’ and ’Dirkwin’) stubble. The triallate granules controlled wild oat (Avena fatua L.), and resulted in increased spring wheat yield. Difenzoquat or diclofop-methyl application also increased wheat yields.Key words: Triallate, oat (wild), conservation tillage, minimum tillage, wheat (spring)

The imidazolinone herbicides possess high biological potency at low application rates, and are an attractive alternative for weed control in spring wheat (Triticum aestivum L.). Four mutation-derived spring wheat lines resistant to the imidazolinone class of herbicides were evaluated in field trials to investigate the levels of resistance to imazamox. Imazamox was applied post-emergence at 0 g (hand-weeded control; HWC) 20 g, 40 g, 80 g and 160 g active ingredient (a.i.) ha-1. A standard herbicide treatment (SHT; clodinafoppropargyl, bromoxynil and MC PA ester) representing a common herbicide application to spring wheat in western Canada was also included. The cultivar CDC Teal was included as a susceptible control. At 160 g ha-1, imazamox reduced yield in lines with a single resistance gene (TealIMI 10A, TealIMI 11A, and BW755) by up to 43% and delayed maturity up to 13 d. TealIMI 15A, the only line evaluated with two resistance genes, was the most resistant of all lines, with no significant increases in days to spike emergence (DSE), days to physiological maturity (DPM), and no reduction in yield at the highest rate of imazamox. The susceptible control was killed within 2 wk of imazamox application, regardless of application rate. These results indicate that two resistance genes are preferable for ensuring satisfactory levels of resistance to the formulation of imazamox used in these studies.
