I know there's been plenty of talk about fungus, but I've gotta ask !

My sister's hoya collection seems to have contracted a fungus and it 'seems' to be spreading
from one plant to another and another. I told her to get a Tinactin spray ( as I was advised years ago ) and spray it on there, coating well. She has done so and has reapplied a couple times. Not sure if it's working though...

I guess it's fungus - it's on the petiole ?, the stems of the leaves and the undersides of the leaves themselves. Seems to be a black and brownish looking stuff.
Anything else work well for anybody ?

Thanks a bunch !

It's all about choices.
DIPEL is a good all purpose broad spec trum fungicide. Are you sure it isn't sooty mold?

Sooty mold = the honey that the aphids excrete is what the ants harvest to feed their larvae. When there is excess honey, it falls on other leaves, and then molds...turns black. Get rid of the aphids and get rid of the ants and when the mold dries up you can spray it off in the shower.... Whistling

Sorry to take so long getting back - I spent 33 hours at the hospital with a friend being her doula.

I don't think it's sooty mold - no aphids or ants. Gotta be fungus. Will we get rid of it by spraying it with Tinactin repeatedly ?

Hard to tell, Paula...not knowing the fungus, not seeing the fungus. You may need to get it tested. I would use a broadspectrum fungicide if you think it is lethal????

Can it be wiped off? If so, she could try spraying the whole plant with Scrubbing Bubbles and rinsing it off and spraying the clean leaves with the Tinactin or fungicide. Also might help to have a fan running around the plants if it is a mold/fungus that is not attacking the plant. Could she have her plants too close together? Is there poor air circulation? I hope she can eliminate it!!!

I had some white stuff on one of mine, and I wiped it off. Dry. I came back after months, but I did it again and it seems to be gone!

Sorry for the delay. I guess I wasn't necessarily looking for an exact identification, just a sort of ruling out of things or ideas for other possibilities. I just don't have time to post a pic. I'm sure it's a fungus - the air circulation is not good and not quite enough light in her house either.

Thanks all for your tips !
