The stalk and leaf stems specks are irregular shaped black to brown in color. Fungus, Virus bacteria? Getting worse!

HELP!
tnsmkr Reviewed by tnsmkr on . Specks on leaf stems? / Orange spots? I took a leaf stem and peeled back the "skin" to see if they were internal or attached. It peeled back with the skin and inside was not infected or discolored. I think it is a mildew or fungus. The specks are semi transparent. The Seranade and sulphur I used was not effective. I think I will try a potassium bicarbonate soloution. What do you think? http://attra.ncat.org/attra-pub/bakingsoda.html Rating: 5
