Control Exobasidium Leaf in Blueberries

Exobasidium leaf and fruit spot of blueberry has increased considerably in prevalence and severity over the past three years, leading to significant yield losses and even abandonment of plantings in some cases. Recent field trials by UGA plant pathologists have shown that the disease can be controlled effectively with a single late-dormant application of lime sulfur, a topical fungicide, providing blueberry producers with a simple and inexpensive means of managing the disease.
