A lack of reduced-risk fungicides makes it difficult to control cherry leaf spot without using traditional chemicals, reports Dr. George Sundin, plant pathologist at Michigan State University, and the best solution could be development of cherry cultivars that are resistant to the disease. Cherry leaf spot is the most economically devastating disease of tart cherry in the Great Lakes area. With future development of leaf-spot-resistant cultivars, fewer fungicide applications would likely be needed, and the disease could be –controlled more successfully, he said. Sundin reported during the Great Lakes Expo in Grand Rapids, Michigan, last December on a four-year tart […]
