    Default encyclia cordigera-scorch?

    This is my encyclia cordigera. It was doing fine with the rest of my orchids but two weeks ago it began what you see in the pics and what Im assuming is scorch. It is in an east window and gets a couple hours of direct morning sun and 4 or so hours of dappled light. The room is bright all day. As you can see it is next to a phalenopsis and gets the same if not less light than the phal. Is this scorch? If so what can I do differently? By the text it should be able to tolerate much more light than this!!

    Looks like a pseudomonas infection to me. I'd remove the leaf immediately.

    As posting of "foreign" URLs is sometimes frowned-upon, I suggest that everyone here do a search for "St. Augustine Orchid Society" and bookmark their photo encyclopedias of plant ailments.

    definitely not from too much light.
    Thanks Ray for directing to St Augustine site! I wasn't aware of it.

    I agree with the previous posts. I have two encyclia cordigeras and they can handle brighter light than most orchids. So the light is not your problem. I would cut that leaf off, like Ray suggested.

    Hi Ray,

    A link to an article on an orchid society website is a welcomed addition as long as it isn't to a commercial site or in violation of our TOC. The only links 'frowned-upon' would be to commercial sites or to pages that list/link to those type of sites. Here is the link to the SAOS-Orchid Diseases page. Looks like a great resource! Thanks for alerting me to this.
    cheers,
    BD

    Thanks everyone for the advice and that website is fantastic! I agree, looks just like the pics of pseudomonas. I will treat today and post follow up pics. Quick question, there are three leaves with just the tips affected. Should I still remove the whole leaf or just infected tissue? Also my orchids are clustered. How contagious is this? Should I use anti fungal on all plants? Should I spray the phasyme solution or dunk them/water them with it? Thanks again all!

    Ok, so upon further inspection of the orchids around the encyclia, things are not looking good... Im assuming its all the same infection as it looks very similar on the pics of the phalenopsis. The oncidium is hard for me to tell, the spots are much smaller and dont have any halo or yellowing around them. Also there are some pics of the encyclia that show the bacteria on the p-bulbs. Its hard to tell but one of the encyclia pics is where I cut back the leaf to the p-bulb but it still has a small section of the infection on the bulb itself. Do I need to cut the bulb off? Does this mean Im prob gonna lose the encyclia? Also the SAOS website said that this is a serious happening for phalenopsis so how concerned should I be there? I've read that physan or phyton 27 can be used to treat. How effective are they? Anyone have more luck with one than the other? Name:  image (10).jpeg

    As far as the Encyclia goes, the solution to your problem would be a lot more light and air circulation. Encyclias are super tough and resiliant when given the right conditions, they like to be bone dry within a couple of days at the most. And all of my encyclias, including cordigera, get full South Florida sun from about 9am to about 1:30pm, and plenty of wind. They could probably take even more sun than that. Good luck to you!

    Thanks gage! Quick update,infected leaves cut from both plants, humidity trays removed from all orchids, bleached and dried, fan on high and copper compounds (southern ag liquid copper fungicide) applied to leaves of phalenopsis and encyclia. Any other advice is appreciated and has anyone used this specific chemical before? Picked it up from "big store anonymous" and it said indicated for bacterial pseudomonas. Lots of warnings on package about wearing protection when using. Is it safe to handle orchid pots after the chem has dried to them?

    Ryan just watch up if some of your orchids may end up with some abnormality to the leaves like mesophil collapsed do not apply any more copper based fungicide as some orchids they are very sensitive to this element, anothe alternative you can use Physan or Thiuram, all the best good luck.
