*sob* Erwinia

Is all your orchids indoors? I remember this time of year the frost comes early in NH...maybe when you turn on your dry heat the bacteria will dissipate and you can catch up on eradicating it. Good luck Mom!

Erwina is terrible. It affects the plant so quickly that by the time you realize whats going on, you've lost 1/2 the plant. I had it this spring on a St Swithin and what was a beautiful 20" ls plant is now a 8" stubbly little thing. But the good news is I saved it. I used hydrogen peroxide daily for 4 days and then every other day for a week.

This stuff is supposed to work wonders on Erwina rots, I have no first hand experience with it, but I was talking to a local orchid grower about my problem after the fact and he told me about this.

yup I think thats what I been calling soft brown rot. It can eat a whole plant overnight and leave it turned to smelly mush.
I cut all the affected parts out or off and treated the wounds with cinnamon.Then a re-pot with fresh mix and no water for at least a week to see what else falls off. I keep them to the side make sure they are okey before I put them back with they buddies missing an arm or a leg. I had a few that got hurt really bad and at some point its just more trouble waiting and they hit the trash can.
I wish you best of luck though in your fight with nature

things seem to be holding steady with Phyton27 and a pack of razor blades.

it's going to be years before I see any more blue ribbons

So sorry to hear of your troubles. Glad to hear it is possibly under control.

I start thinking as I read this that I had a narrow escape from this.

I spotted a leaf on a phal which had overnight turned to soft brown mush from half way along to the tip. I cut it off well into the good tissue and put cinnamon on the cut and nothing else ever came of it.

I had intended at the time to post a picture here and ask you guys what you thought of it, but I never got around to it. Now from all the descriptions it sounds like it could be this nasty thing.

So glad I spotted it early and did the right think removing the infected tissue.

[fishmommy]

yep, that sounds like the same problem - great that you caught it early, since it moves very fast!

[fishmommy]

update - things are under control I believe thanks to strict hygeine and Phyton 27.
Jury is still out as to whether I will lose my Paph Ho Chi Minh but everything else is doing well.
It will be a loooong time before I can stop obsessively checking everything but so far so good.

Although the linked study was done primarily for commercial growers, the results are applicable to home growers equally.
