APPLICATIONS

Mode of action: Fungicide with protective, curative, eradicative and long residual disease control; Acts by inhibiting spore germination. Redistribution via the vapour phase contributes to activity.

Uses: Control of scab in apples and pears (Venturia spp. ); Powdery mildew on apples (Podosphaera leucotricha), vines (Uncinula necator), cucurbits (Sphaerotheca fuliginea) and sugar beet (Erysiphe betae); Mildew (Erysiphe graminis), scald (Rhynchosporium secalis), net blotch (Pyrenophora teres) and glume blotch (Septoria nodorum) on cereals; Mildew on vegetables (Leveillula taurica, Erysiphe spp., Alternaria spp. ).
