I bought a Cavendish at Home Depot a couple of months back. It has grown very quickly and looks great. However, the bottom leaf started looking bad (yellow veins; brown on the end) a few days ago and now the next few leaves are peppered with tiny black spots.
Is this black sigatoka? If so, should I dig it up and toss it? I have two ice creams, an African Red, and another that I can't remember the name of (blush), and I don't want to lose them. From what I read on Wikipedia, black sigatoka will kill my Cavendish and can't be treated. I'd rather lose the one (albeit lovely) Cavendish than the rest of my babies.
Thank you in advance to anyone who can weigh in. For some reason, I've only been able to upload one picture (below).
