| Looks like rust fungus. Neem oil should clean that up for you. If you're watering with a sprinkler, I'd stop that to keep it from spreading more... Can't stop the rain, though. If you feel it's too late in the season to treat it, be sure to NoT compost the plants after frost, as the spores will hang out and have a party at your expense. |
