I sent her to Sam's to pick up the ProForce, but she got the oven cleaner as opposed to the disinfectant. So she's going back today to exchange it and I'll have to do it after work. That does sound like what this is. I just can't believe how quick it spreads. I have one little guy that only has two psuedobulbs and it has already spread into them so I have a feeling he's not going to make it. If the disinfectant does work the rest might live but they will have to be cut way back. Thanks for all of the suggestions so far.

I stopped off at a friends house on the way home from work. He showed me his catt that he moved cause it got 'sunburned' and there it was a black leaf. Soft to the touch. I asked him how he figured it was sunburned when it was in such a shaded area under a tree. I couldn't help but think of yours. I will be keeping an eye out to see if it spreads or heals. He would be devestated if it spread a lot. That catt is huge and beautiful.

Absolutely, that was my mistake. I thought sunburn at first, put them in the shade and didn't give it much thought until about 3 days later and by then it had just exploded.

It looks to me like they got sunburn which caused a secondary infection. It's like with us, we get little sleep for a week, then someone sneezes on us and we are sick. Basically the immune system gets compromised, and you are susceptible to a host of things. Another thing, if you have had a lot of rain, water sitting on the leaves can magnify the effects of the sun, effectively boiling the area underneath it. You said that the roots look good, so that is what led me to my conclusion. Also I have grown Catts, and Dends outside for a couple of years, and my Catts sulked a lot when I had them with the Dends. I moved them this year to a shadier area, and they are growing like weeds. I am glad to hear that you have gotten the problem under control.
