The goal\nwas to assess the influence of spraying related factors on efficacies of antifungal treatments. The\nfeatures of the sprayer enabled each spraying method to be replicated many times across the vine\nblock. In both experiments, the effect of spraying methods on powdery mildew control could be\ndistinguished and interpreted because of the spatial analysis of disease pressure within the vine\nblock. The findings are a contribution to new methodologies for studying how to apply biological\n(biocontrol) plant protection products.\nKeywords: checkerboard design, plant protection, precision viticulture, spatial variation","language":"eng","keywords":["Vigne"],"project":{"code":"25PIT080","name":"Programme annuel IFV 2025"},"notice-url":"https://hal.inrae.fr/hal-05175506v1","document-url":null,"productions":["vine","vine_nursery"],"taxa":["vitis"],"production-systems":[],"areas":[],"pests":[]}
