Plasmopara viticola disease incidence and severity in inflorescences (BBCH 71 – 2016) and grapes (BBCH 75 and 88 – 2017, 2018). Disease incidence (black bars) and disease severity (grey bars) were quantified over three seasons in the grapevine cultivars ´Sauvignac´ (Rpv12/Rpv3), ´Cabernet Blanc´ (Rpv3) and ´Kerner´ (susceptible), differing in the number of fungicide applications during the season. The bars show mean values for two different locations in 2016 (n (grapes/application number) = 200) and from three different locations in 2017 and 2018 (n (grapes/application number) = 300) for ´Sauvignac´ and ´Cabernet Blanc´. Data from ´Kerner´ are mean values of one location n = 100. Error bars show standard error (SEM); no infections detected (n.d.). Kruskal-Wallis and Conover-Iman test was used to compare the disease incidence (A, B, C) and severity (a, b, c) for each year, p < 0.05
