Collis

Collis is a fungicide combining kresoxim-methyl (100 g/L) and boscalid (200 g/L) in a suspension concentrate (SC) formulation. It controls powdery mildew (oidium, Uncinula necator) on grapevines and moves within the plant both translaminarly and systemically. The two active ingredients act at different points in fungal energy metabolism, which supports resistance management. It is applied during the growing season at 0.4 L/ha, with up to three treatments spaced at intervals of up to 14 days.
