TOXICOLOGICAL ASSESSMENT OF FUNGICIDES FOR PATHOGENS OF PYRENOPHORA TRITICI-REPENTIS (DIED) IN WINTER WHEAT
Abstract
The article describes the laboratory experiments made to determine median toxic concentration (TC50) of fungicides taken from different chemical groups such as triazoles, strobilurins, morpholines and used both separately and in mixtures with fungicides for pathogens of Pyrenophora tritici-repentis (Died). One-component drugs from triazole group have been given, as ‘Reks S’ - CS of 125g/l, ‘Tilt’ - EC of 250 g/l and ‘Folikur’ - EC of 250 g/l. From strobilurin group we took ‘Optimo’ - EC of 200 g/l and some mixed fungicides, as ‘Alto turbo’ - EC of 250+160 g/l, ‘Alto super’ - EC of 200+80 g/l, ‘Broader’ - EC 150+150 g/l, ‘Abakus ultra’ - SE of 62,5+62,5 g/l, ‘Konsul’ - CS of 125+125 g/l, ‘Amistar extra’ – SC of 80+200 g/l and ‘Reks ultra’ – SE of 84+250 g/l. Toxicity of studied fungicides for pathogens of Pyrenophora tritici-repentis (Died) varied from strong toxic 0,33 mg/l to less toxic 2,29 mg/l according to median toxic concentration (TC50). The given results comply with previously published data about fungicide efficiency for pathogens of Pyrenophora tritici-repentis (Died) on winter wheat.
