Context 1
... evolution of the disease on the grape bunches, very rapid in 2018, was slower in 2019. The results obtained in the 2018 trial are reported in figure 1 and figure 2 for the disease incidence and disease severity, respectively. Similarly, in figure 3 and 4 the results obtained in 2019 are presented. ...

... both the assessments, the milk powder was significantly different from the untreated control, providing a disease control similar to that provided by the sulphur-based plant protection product. The efficacy in reducing the disease severity ( figure 2) was close to 95-99% regardless the tested concentration of the milk powder, while concerning the disease incidence ( figure 1) a numerical dose-effect was observed among the three tested dosages (milk powder at 10 g/L, 20 g/L and 30 g/L, the latter with the highest performance). In the second and last assessment (7/9), when the crop was at BBCH 81 (beginning of berries ripening), the milk powder applied at 30 g/L provided a protection of the grape bunches numerically better than the sulphur reference standard. ...
