Eficienţa biologică a unor noi produse cuprice pentru combaterea ciupercii Plasmopara viticola (Berk. et Curt) Berl. et de Toni

Abstract

This work presents results of biological efficiency test of the copper preparation Abiga Pic, VS, CuproStar 46 SC, Cuprilat, WG and Cuper 240 SE as a fungicide aganist fungus at vine Plasmopara viticola (Berk. et Curt) Berl. et de Toni. The obtained experimental data prove that the biological efficiency of the preparations CuproStar 46 SC, Cuprilat, WG, Cuper 240 SE and Abiga Pic, VS was lower than the standard in the first dose and the same level as the standard in the second dose. To control fungus at the biological cultures of the vine, beside those 10 preparations registered on the Moldovan Market there is proposed the homologation of some new fungicides like: Abiga-Pic, VS (5,0-7,0 l/ha), CuproStar 46 SC (4,0 l/ha), Cuprilat, WG (7,0 kg/ha) and Cuper 240 SE (5,0 l/ha), 2-3 treatements in the vegetation period.
