This is identification help, not a diagnosis.
Symptoms described here can overlap between diseases and other causes (drought, wear,
nutrient deficiency). When you're not sure, or before applying any treatment, contact
your state's Cooperative Extension office - most offer free or low-cost diagnosis and
know your local conditions best.
