Noi fungicide pentru combaterea ciupercilor Plasmopara viticola, Uncinula necator şi Botrytis cinerea

Abstract

This work presents results of biological efficiency test of the preparation Rovelin 500 WP, Synothiophanate 70 WP and IQW 033 25 WG as a fungicide aganist grey rot (Botrytis cinerea Pers.), powdery mildew (Uncinula necator Schw.) and downy mildew (Plasmopara viticola Ber.et de Toni). The obtained experimental dates proves that the biological efficiency of the fungicide Rovelin 500 WP in a dose of 2,0 kg/ha and Synothiopanate 70 WP in a dose of 1,7 kg/ha, aganist grey rot, is on the level of the standard. Fungicide Synothiophanate 70 WP aganist powdery mildew in dose of 1,7 kg/ha showed a higher biological efficiency than the standard (Topsin M 70) both on the leaves and the grapes. Aganist the downy mildew the biological efficiency of the fungicide IQW 033 25 WG in the dose 1,0 and 1,5 kg/ha showed a higher biological efficiency than the standard (Ordan SP 3,0 kg/ha).
