You will have to use fungicides to cure this. Cut off any infected growth and keep any infected growth raked up away from the plant to prevent further spreading.

Many times, this is caused by the soil remaining too wet for too long. If you provide supplemental watering, you will want to do so only after the first 2 or 3 inches of soil is completely dry to avoid future infections.
