It had to happen. We have had nonstop rain for several days. I noticed the first catt. It had come up over night and was contained to a leaf. I excised down to the pb. poured peroxide on the cut and isolated it. Just found the 2nd catt, again contained to a leaf.
Before I start spraying with D. M45 the rest of my collection does anyone think a systemic fungicide might be a better choice??
