Impact of disease severity on infected bunches upon a yield of grape variety Vranec, caused by Plasmopara viticola (Berk. & M.A. Curtis) Berl and De Toni

Impact of disease severity on infected bunches upon a yield grape variety Vanec, caused by Plasmopara viticola (Berk. & M.A. Curtis) Berl. De Toni., every year causes damage to the vines infection while they are still unripe. It is essential assess Downy Mildew in vineyards predict loss accurately. The software platform 'image J' was used detect and quantify measuring berries relative healthy tissue. Regression analysis as statistical method loss. monitored 2022 find rational solution build Yield Loss Forecast Model. results theoretical assumptions compared with actual field situations show that Forecasting Model within allowed range approximately predicts control variant.
