The article deals with the results of production comparative experiments of fungicides applied in the flowering phase of winter wheat in the Stavropol region in the zone of unstable humidification. It was found that the maximum biological efficiency against fungal diseases within 24 days fungicides containing active substances prochloraz + tebuconazole and diphenoconazole + tebuconazole possess. The highest yield was obtained in the variant where we applied fungicide with active substances prochloraz + tebuconazole with a rate of consumption of 1.2 liters / ha 69.2 kg / ha this is 2.7-7.7 kg / ha more than in other variants. It was found that the mass of a thousand grains is directly correlated with yield, in the variant with the use of fungicide with active substances prochloraz + tebuconazole the mass of a thousand grains was the maximum 45.4 grams. Phytoexpertise of seeds showed that the lowest content of fusarium grains was in the variant with the use of fungicide with active substances prochloraz + tebuconazole. Not high content of fusarium grains 1.7-2.0 % was in the variants where we treated with fungicides containing active substances diphenoconazole + tebuconazole and spiroxamine + prothioconazole.

“…The use of herbicides is seen as the most effective means of redroot pigweed control in cropping systems of wheat fields, allowing for short period management. Hence, Glazunova et al (2015) reported that redroot pigweed density was desirably reduced by the use of postemergence herbicides in wheat fields of Russia.…”

Redroot pigweed (Amaranthus retroflexus L). is a broadleaf weed in autumn crop fields in Russia. Four field experiments were performed in Stalskiy region, southern Russia in two growing seasons, 2016 and 2017, to investigate the effects of postemergence applications of applied alone or in tank mixtures in winter wheat cultivars Tanya and Bagrat. Redroot pigweed control was greatest with tribenuron and all herbicide treatments containing tribenuron. The lowest redroot pigweed control was with aminopyralid/florasulam (study 1) and triasulfuron (study 2), respectively, whereas redroot pigweed had intermediate responses to the other examined herbicides. Tribenuron plus fluroxypyr sprayed on wheat cultivar 'Tanya' , and tribenuron plus triasulfuron on wheat cultivar 'Bagrat' resulted in increased wheat grain yields. Overall, tribenuron and herbicides containing tribenuron provided the most efficient redroot pigweed control compared with the other herbicides and consistently maintained optimal winter wheat yields. Tribenuron could ameliorate redroot resistance to herbicides in wheat fields in southern Russia.

“…It is an annual or perennial seminiferous plant, hibernating, climbing, rough to the touch and sticky, which causes direct damage to barley production through the consumption of water and nutrients, but also indirect damage because it makes harvesting difficult and is a host plant for nematodes, insects and pathogens(Ştef et al 2020). It is a hard to control weed as over the last decades the research carried out has clearly shown that this species is resistant to 2,4-D and MCPA, herbicides frequently used to control weeds in wheat crops(Glazunova et al 2015;Zargar et al 2020). Cases of high levels of resistance to herbicides that inhibit ALS (chlorsulfuron and tribenuron) have also been reported, as well as situations of additional cross-resistance to florasulam + 2,4-D(Papapanagiotou et al 2019).…”

During 2021-2022 two fields trial with the winter barley variety "Lucian" was conducted. The studys was conducted in 2 different locations (Constanța and Călărași) and aimed to evaluate the biological activity of two herbicides based Fluroxypyr and Florasulam in control of broadleaf weeds in winter barley crops. The experiments were placed in randomized blocks, in 4 repetitions with a plot area of 100 m 2 . Efficacy and selectivity of the herbicides Flurostar Super SE (100 g/l fluroxypyr +1 g/l florasulam) and Tomigan XL 102.5 SE (100 g/l fluroxypyr + 2.5 g/l florasulam), applied at registered and higher rates, was evaluated. The herbicide application was done at the phenophase of the crop -1st -2nd stem node (ВВСН 30-32). The efficacy of the products by the 10 score scale of EWRS was recorded. The results were compared with untreated controls. The herbicide selectivity for the winter barley by the 9 score scale for phytotoxicity of EWRS was reported. The results obtained showed that the efficacy depends on the dose applied, the type of weeds and their density on square meter. The herbicide based floroxypyr and florasulam ensured a good efficacy in controlling of broadleaf weeds in winter barley, the best results being obtained at the higher dose. For both herbicides (Flurostar Super and Tomigan XL) at all evaluated rates signs of phytotoxicity for the crop were not observed.
