Guelph, ON (April 19, 2016) – Bayer has announced the launch of Priwen fungicide for control of powdery mildew in Canadian wine grapes.

“At Bayer, we are dedicated to pursuing new tools that address specific needs for growers,” said Jon Weinmaster, Portfolio Manager, Horticulture, at Bayer CropScience Inc. “As the only Group 5 fungicide available for wine grape growers in Canada, Priwen not only offers growers a new and unique foliar fungicide, but one that is highly effective against powdery mildew.”

Priwen offers xylem-mobile systemic protection, moving to the leaf tips and underside of leaves.

“Thanks to its unique active ingredient, Priwen is also an excellent rotation and resistance management tool, which supports wine grape growers’ efforts to manage tough diseases year after year,” said Weinmaster.

Priwen is formulated as a 500 g/L emulsifiable concentrate and is available in 1L jugs, with 12 X 1L jugs per case.

For more information regarding Priwen, growers are encouraged to talk to their local retailers, visit, or follow @Bayer4CropsCA on Twitter.
