Huntleya wallisii new bloom with sunken dimples

[lotis146]

Hello I'm back with a different plant problem!

My Huntleya wallisii just bloomed again and almost immediately it seems (within a couple of days maybe a little longer) these sunken circular spots appeared on the flower. They're like little crop circles. They're on every petal/sepal & the first to show them is now darker in color & shriveled.

Overall the plant seems healthy, I mean it's lost some leaves one being younger on the main growth but it also has new roots, this bloom AND two new growths at the base. There is some spotting & streaking on leaves here and there but my understanding is that Huntleyas will get the familiar Zygo spotting (as they are part of this family). Btw, this is not the same problem I had with my Huntleya Pallida which is doing well now.

You can see in the following pics that these spots are not difficult to see at all. Is this fungal or pests? Any advice is much appreciated. This plant is hanging above the Aganisia I wrote about before that as one member has said probably has Anthracnose.

The bloom is more than half shriveled over now. I'm fearing a pest of sorts b/c it's moving from one petal/sepal to the next... any ideas?

My guess... Maybe fungal petal blight? Maybe use an antifungal, increase air flow, and reduce humidity. Keep the plant away from the others.

I've sprayed it with Inocucor, need to again today and moved it from the bunch. The bloom is mostly shriveled now. It's outside so the air flow is good but humidity would be lower inside. I think I'll send Andy an e-mail too and see if he's dealt with this before. Thanks Colette.

Fungal for me, there's marks of progresses. More air!

I'd cut the offending parts, eventually treat with a systemic. The dead parts are contagious.

I just thought of this - Take a damaged flower to your local county agricultural extension agent. They are usually happy to help identify pathogens.

I think its fungal as well.

These guys are extremely prone to fungal infections.

Getting them tested is also a plus, just to confirm whether it is truly fungal or not.
