[en] Trifloxystrobine-based fungicides were tested for two years in winter barley and three years in winter wheat in Belgium. One or two applications were compared with other strobilurine based fungicides. The efficacy of the combinations of trifloxystrobine (125 g/ha) + propiconazole (125 g/ha) and trifloxystrobine (125 g/ha) + cyproconazole (80 g/ha) for disease control in winter barley and winter wheat, respectivvely, was confirmed. They allowed yield increases comparable to those obtained with kresoxim-methyl and azoxystrobine-based fungicides
