Control of powdery mildew in cereals (Erysiphe graminis), at 500-750 g/ha, and in grapes (Uncinula necator), at 400 g/ha. Also gives good control of rusts (Rhynchosporium and Pyrenophora teres), together with certain side-effects against Septoria diseases. Penetration studies have shown that tank mixes of spiroxamine and triazoles can positively influence the uptake of triazoles in plants.
