Symptoms first appear as brown or necrotic areas at the ends of leaves and look like a tipburn.
Affected tissues are tan at first and turn brown with age. The fungus grows into the leaf from the tip until the entire leaf is affected. These leaves turn brown and drop. Control strategies include careful attention to watering since these fungi can be easily spread with splashing water. Additionally, watering early in the day helps to minimize the chance for long periods of leaf wetness which favor disease.
