Weed resistance got attention with the upsurge in waterhemp, Palmer amaranth and kochia. BASF technical market manager Steve Broscious says disease resistance is also becoming more common. “All crops have some level of reduced sensitivity.” BASF has a new active ingredient coming to the market. With that, Provysol is being sold to protect potatoes from early blight and protect sugarbeets from cercospora. Provysol is a Group 3 fungicide. “Many of the products used today are Group 7 and 11. When we use them too often, we put a lot of pressure on them relative to resistance development. With the advent of Provysol as a Group 3, we can rotate and keep the products for a longer period of time.”
