Journal Title: International Journal of Humanities and Social Science Invention - Year 2017, Vol 6, Issue 9
Abstract
The investigation was carried out during 2011.2012 and 2017 seasons in Marikaj in Tirane Capital, Tirane – Durrës desert road under natural infection conditions. The efficacies of Solfato di rame 20%, Algae extract, Clay with Al-sulfate, Algae extract with potassium \ Phosphomat and alternate, against downy mildew were studied on grapevine cv. Merlot. All the tested compounds provided protection at different level against downy mildew [Plasmopara viticola (Berk. et Curtis ex. de Bary) Berl.] on both leaves and bunch as compared with contoll which record the highest effect. Solfato di rame 20%, Alternate, Clay with Al-sulfate and Algae extract with potassium \ Phosphomat were more effective on leaves and bunch as compared with used in a single treatment. From the data we see that the lowest index on the leaf and thus coat the Imc in% of the downy mildew (Plasmopara viticola (Berc and Curt) have the variants where we have used Biological Alternative products and Cuprozin fl respectively Imc = 9.5% and 11.5% in leaf as well as 4.94% and 5.58% in coats compared to the control variant that is 66% in leaves and 57.5% in coats. Satisfactory results have yielded Bioproducts such as Muco-Sin, Frutogard and Algin Biovital, respectively Imc = 15%, 16.6% and 17% in leaf as well as 9.91%, 13.08% and 11.83% in Woolly compared to the control Which in Imc's leaf reaches 66% and wears 57.5%.
