The Role of Pest Control Advisers in Preventative Management of Grapevine Trunk Diseases

摘要: Vineyards with trunk diseases (Botryosphaeria dieback, Esca, Eutypa and Phomopsis dieback) can have negative returns in the long run. Minimizing economic impacts depends on effective management, but adopting a preventative practice after infection occurs may not improve yields. Pest control advisers reduce grower uncertainty about efficacy of need for prevention, which often entails future unobservable benefits. Here, we surveyed California to examine their influence over decision-making, context diseases, significantly limit grape production curative practices are unavailable. Our online survey revealed adviser awareness high disease incidence, reduced yields vineyard lifespan. Advisers rated both postinfection positively. Despite higher cost estimates given practices, did recommend at rates. High recommendation rates were instead correlated incidence practices. Recommendation declined increasing preventative, postinfection, findings suggest that even when acknowledge risks they before occurs. This underscores importance clear outreach, emphasizing prevention its long-term efficacy.
