Per Requester: Very Good Fit; Propamocarb hydrochloride is a downy mildew fungicide with a mode of action not currently registered in hops. Propamocarb hydrochloride is a downy mildew fungicide. Registering this product will benefit hop growers with new mode of action and will relieve some of the resistance management concerns the hop industry has for the few downy mildew fungicides presently registered on hops. Resistance is in documented in the hop downy mildew organism to phenylamide (group 4) and phosphonate (group 33). Resistance to multiple other groups are documented in the sister species, Pseudoperonospora cubensis:08/23
