RANMAN 400SC FUNGICDE

Cyazofamid is the active ingredient in Ranman®, a targeted FRAC Group 21 fungicide used by Canadian potato growers for the preventative control of late blight (Phytophthora infestans). It works by inhibiting fungal respiration, disrupting energy production and preventing disease development before infection can spread. Its unique mode of action makes Ranman an important resistance-management tool and an effective rotational partner with fungicides from other FRAC groups.

For potato growers, Ranman delivers excellent late blight protection through strong preventative activity, anti-sporulant effects, outstanding rainfastness, and long residual control. It helps limit spore production and disease spread during periods of high pressure, protecting both yield and tuber quality. Ranman is also well suited for ground or aerial application, allowing growers to efficiently protect large acreages when weather conditions or crop canopy make timely coverage critical. Its reliable performance and flexibility make it a key component of modern Canadian potato disease management programs.
