Every year is different, but we often see certain diseases routinely such as root rots like Rhizoctonia, Pythium, and Fusarium. Other diseases we may only experience during certain years when conditions are conducive for pathogens growth or spread. The weather we experienced this year had an impact on the environmental conditions leading to more infrequent disease or conditions like Downy Mildew, Ascochyta Blight, Snow Mold, Bacterial Leaf Spot, and Physiological Leaf Spot.
