The influence of herbicides and their mixtures on weed infestation of crops and yield of spring wheat

 The articlepresents the results of studies on the action of herbicides and their mixtureson the contamination of crops and the yield of spring wheat. Research on the effectof herbicides and their mixtures on the contamination of crops and the yield ofspring wheat was carried out in LLP “Atameken-agro” of North Kazakhstan region.Herbicides against dicotyledonous weeds reduced weed infestation by 87.5 %(herbicide “Zenit”) and 78.0 % (herbicide “Esteron”), the number of monocotsincreased by 2 pcs/m2. Tank mixtures of herbicides contributed to thedestruction of both monocotyledonous and dicotyledonous weeds. More effectivein the fight against weeds worked tank mixture of herbicides “Argo” + “Zenit”,where the death was 86.7 %, the combination of “Puma Turbo” + “Esteron” ensuredthe death of weeds by 77.0 %. The difference in the degree of clogging betweenthe applied herbicides “Argo” and “Puma Turbo” was 0.9 %, i.e. the herbicide“Argo” worked more effectively; between the herbicides “Zenit” and “Esteron” –1.1 %. The degree of clogging in the application of the tank mixture ofherbicides “Puma Turbo” + “Esteron” is higher by 1.1 %. The use of herbicidesprovided an increase in yield of 0.3–0.5 t/ha (17.6–29.4 %) for options withthe use of herbicides “Argo” and “Puma Turbo”, 0.6–0.8 t/ha (35.3–47.1 %) withherbicides “Zenit” and “Esteron”, and 1.1–1.4 t/ha (64.7–82.4 %) using a tankmixture of herbicides as a result of less contamination. The herbicide Argo providedan increase of 0.2 t/ha more than the herbicide “Puma Turbo”, in the variantwith the herbicide “Zenit” above 0.2 t/ha compared with the herbicide “Esteron”and the tank mixture of herbicides “Argo’ + “Zenit” provided a large increasein relation to the control (1.4 t/ha) and the difference between these optionswas 0.3 t/ha.
