Английский. Laboratory, greenhouse and field experiments were performed on vegetable, fish and mineral oils to evaluate their phytotoxic effects on grapevine and their effectiveness in the control of grapevine powdery mildew. None of the tested oils showed detectable phytotoxic effects at concentrations of 2% or less applied up to 4 times per week. In greenhouse trials, the efficacy of paraffin oil, refined rapeseed oil and partially refined fish oil against powdery mildew was similar to that obtained with the standard fungicides (tebuconazole or colloidal sulphur). In field trials, the three tested oils (paraffin oil, crude soya oil, and fish oil: 1% in aqueous emulsion) were at least as effective as the standard fungicide quinoxifen, with crude soya oil being the most effective. The oils used in the field trials were also effective for controlling eriophyd mites such as Calepitrimerus vitis

[Sono state effettuate prove in laboratorio, in serra e in campo su oli vegetali, minerali e di pesce per valutarne gli effetti fitotossici e la loro efficacia nel controllo dell'oidio della vite. Nessuno degli oli sperimentati ha mostrato effetti fitotossici a concentrazioni del 2% o inferiori applicati fino a 4 volte per settimana. In serra l'efficacia dell'olio di paraffina, dell'olio di colza raffinato e dell'olio di pesce parzialmente raffinato nei confronti dell'oidio è risultata simile a quella riscontrata con i fungicidi standard (tebuconazolo o zolfo colloidale). In prove di campo i tre oli sperimentati (olio di paraffina, olio di soia grezzo e olio di pesce: 1% in emulsione acquosa) risultavano altrettanto efficaci quanto il fungicida standard quinoxifen; l'olio di soia grezzo si è dimostrato il più efficace. Gli oli utilizzati nelle prove di campo sono pure risultati efficaci nei confronti degli acari eriofidi, come Calepitrimerus vitis.]
