Fungicidal control of white cabbage against Alternaria brassicae (Berk.) Sacc in the conditions of the Forest Steppe of Ukraine
Abstract
Purpose. The aim of the work was to investigate the effect of modern fungicides on limiting the development of the most common diseases, namely Alternaria of white cabbage in the forest-steppe zone of Ukraine. Materials and methods. Field (setting up experiments, damage records, harvesting), phytopathological (identification of pathogens), information-analytical (collection and analysis of literary sources), mathematical-statistical (processing of research results). The research was conducted in the Cherkasy region at the Rusalivka State Agricultural Production Association. Fungicides with different active ingredients were studied: adepidine, fluopyram+tebuconazole, trifloxystrobin+ tebuconazole, iprodione, difenoconazole+ fluxapyroxad, boxalid+pyraclostrobin. Research Results. Alternaria, the causative agent of Alternaria brassicae, had the greatest spread and development during the years of research, in connection with the formed weather conditions. To protect against diseases, fungicides were used: Miravis 200 SC, KS; Luna Experience 400 SC, KC; Nativo 75 WG, VG; Rovral Aquaflo, KS; Serkadis Plus, KS; Signum VG. As a result of research, we established that the effectiveness of modern fungicides was on average 51.4-82.2%. The highest effectiveness against cabbage alternariosis was noted for the use of Miravis 200 SS, k.s. – 0.35 l/ha; Luna Experience – 0.75 l/ha; Nativo 75 WG – 0.35 l/ha. The saved harvest with the use of drugs was 5.7-13.7%. Conclusions. It was established that the most effective modern fungicides against cabbage Alternaria (Alternaria brassicae) in the conditions of the Forest-Steppe of Ukraine are: Miravis 200 SC, hp – 0.35 l/ha; Luna Experience – 0.75 l/ha; Nativo 75 WG – 0.35 l/ha. With double spraying with drugs, the effectiveness of the action was on average from 75.0 to 82.2%. The use of drugs allowed to obtain 4.0-4.5 t/ha of additional stored yield of white cabbage heads.
