I stand corrected; use of a company name, despite the unofficial nature of my communicae, was somewhat inappropriate. Still, I do have a background in botanical studies and possess the necessary books and equipment which strongly support my conclusion. In addition, I have never registered a complaint against the company for any reason. -- Nonetheless, it Is yellow Sigatoka I observed under my microscope. The source of the infection is, naturally, entirely unknown (the plants and packaging pass through many hands enroute) and even a mailman might have come in contact with the fungus prior to delivering the mail.
Shock & subterranean afflictions typically project a limp condition in the fibers of the plant - the plant is agreeably supple and firm. I have every intention (after the holiday) of contacting the company owner (whom I happen to like and have spoken with before) to alert them to the problem. In doing so, solutions might be found to help prevent any further mishaps.
Back to the problem at hand : Though I'm unfamiliar with the actual chemical pathways involved, I understand that the copper sulfate is an effective cure for the fungus. The second of the 2 plants seems perfectly healthy (which also leads me - and should lead others - to believe that the source of contamination was likely during the delivery process). Temperatures (over the past week) have been in the 60's, at night, and the 80's to 90's during the day. With such favorable conditions, I elected to plant them directly outdoors in 75% sun and a ground mixture of 1/2 sandy loam & 1/2 crushed oak leaves (my other banana species have thrived well, for years, under the same conditions). Also, while I water them well, I never allow them to stand in water and do allow a period in which they dry out. -- The question still being, with the fungicide applied, is there a chance that the 3rd (still unfurled) leaf might survive?
