Phal problem. Help!
I have a group of Phals, some of which I have had FOREVER.
For over a year now, they have had a problem that is slowly killing them. I just now finished making a simple web site that shows and tells about the problem.

Thank you Cecil. I can assure you it is not scale. The spots are all
sunken pits and not raised bumps. Your reply does tell me that the pictures are working now which is really good news. Steve Cecil Kimber wrote: Looks like scale to me.

I agree it resembles sunburn but it isn't. I have had several leaves
look like that in areas where direct sun never touches. I have plants with sunburn but not the Phals.

Not that I've ever seen it myself, but I am reminded of the
mysterious "microfungus" that has been described elsewhe http://www.orchidmall.com/general/microfun.htm One curative consists of Ortho malathion and Funginex: http://www.chebucto.ns.ca/Recreation.../magnov95.html Another alternates 3 fungicides: http://www.soos.ca/Newsletters/2002/May2002News.htm I personally know nothing about it and, to make things worse, had to manually enter the above URLs so I *hope* they work- no cut and paste.

I've had it for two years now and it's actually two phals connected in one s/h pot. Anyways, Spring of '02 both phals started getting the yellow leaves with black pitting. When it first started it was sudden. Lowest leaf on both phals, then the next lowest leaf. Sunken yellow spots turning to black. I isolated it to another room and sprayed with funginex. That seemed to stop it. No more spread to the other leaves. This spring it started up again on one phal but this time on the newest leaf growing from the crown. Funginex didn't stop it this time. So I started cutting it and soaking the leaf in physan (one week) and RD20 (the next week) it stopped. Not sure if this helps. Maybe I should send a leaf in for testing. |

Aaron pointed out the link, and he didn't even say that the information was
correct, did he? Mixing chemicals without precise knowledge of potential reactions is risky. I haven't read the article, but the malathion and Funginex mixture , for example, is likely replaced with Orthenex - Orthene and Funginex. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . .

This looks just like the fungus that infected my phals a few years back
and it also spreads to Cattleyas, oncidiums, etc. I found that I needed to soak the plants regularly with Funginex for many waterings or the fungus would just continue in the new leaves. You need to treat the other plants also, maybe not as frequently if they have no symptoms. The fungus does spread rapidly. I lost some phals and saved some. It took me a while to realize that just one or two treatments was not enough. You might also try sterilizing the pots, trays, bench, etc with Physan.

Phal problem. Help!
Ray,
I am in agreement with Aaron, I think Steve has a microfungus. I was guessing that before I even saw the pictures. I have had microfungus on phals, I have cured it. But the only way I have successfully cured microfungus is using a cocktail of chemicals. Two months ago when I mentioned a cocktail Aaron replied with a post about not mixing chemicals under the risk of toxic precipitate and wrecked buffers. Not wanting to hear this crap again, I took my discussion with Steve out of the group. I just find it maddening that today Aaron is giving pointers to sites promoting chemical cocktails. Pretending that you know more then the chemical manufactures or the directions supplied with the chemicals does a disservice to this group. Is the label that comes with the chemical the "precise knowledge" we must know or is there more? If we follow the label are we still going to create toxic precipitate? If I am Steve, who or what do I believe? Chemical labels includes a section on compatibility and yes you better read them and follow the directions. Randomly mixing any chemicals is a dumb idea. But, when you take copper out of the mix, it seems that most of the chemicals I commonly use are compatible. I am not making that up, it is what the labels say, it is what experience has shown. Some of the more common cocktails are even marketed as a single product, Spectro and Banrot to name two. BTW, I highly recommend Spectro which is a cocktail of 3336 and Daconil as a broad spectrum fungicide. Sorry about the double post, I would blame my ISP but who would believe me.

Pat,
I agree that expounding more than the chemical companies know is a disservice, but I didn't do that, and neither did Aaron. I work for a chemical company and part of my job is doing just that. The only thing I referred to was Orthenex, which is Orthene and Funginex in an oil solvent, and Aaron did nothing but point folks to websites containing something that they might want to consider all by themselves. I don't know what got your feathers ruffled, but your responses - to Aaron originally, then to me - seem a bit belligerent, and definitely a disservice to the folks here. -- Ray Barkalow - First Rays Orchids - www.firstrays.com Plants, Supplies, Books, Artwork, and Lots of Free Info! .. . . . . . . . . . .

This term "microfungus" is new to me. I looked at the pictures on Steve's
website again with this is mind and wonder why there seems to be so many different expressions of damage? It is hard to see all of the various damage symptoms as common to one organism, but I suppose it is possible. I did a websearch and found a few bits of information. I want to know whether this is an organism that lives IN and spreads though the plant or if it live ON the plant's surface tissue. Fungi, as I understand them have several life stages. At some point it has to reproduce and would make fruiting bodies at the surface of the leaf that would spread it to new plants. If the "mycelium stage" of the fungus lives inside the plant and travels from cell to cell than wouldn't you need to target it with some kind of systemic fungicide that the plant could absorb rather than a topical fungicide that? Is it living off the tissue like a parasite or just clogging transport of nutrients and water as it grows from cell to cell, and tissue type to tissue type etc? How is a microfungus different from the regular fungus that we as orchid growers are always battling? (You know, the stuff we call 'rots' and which could as likely be a bacterial infection.) Is Physan systemic? I know it kills spores on surfaces but would it have any effect on fungus growing inside and being protected by the plant tissue from coming into contact with the chemical? This may be the reason behind the cocktail idea, one to kill the spores outside the plant and one to kill the actual fungus inside the plant. Daconil is systemic, right? Is there another reason why a cocktail is necessary? (We don't really know what it is so we hit is with everything we've got?) :-) You don't necessarily have to MIX the chemicals to have them both available for use. You might be better off to separate their application by a few days to produce the desired effect. "Pat Brennan" wrote in message ...

If this microfungus is a single organism, it might be that a single product will cure it. It might be that this is a problem that isn't figured out yet and nobody has stayed with one product long enough to find out that it's the one that works. As far as my plants having different problems, I believe they do. The pitting that seems to be from this microfungus is what started first but I think one or more other rots have invaded through these injured areas. This second disease my be spreading first to some of the other plants. Steve |

Thanks Aaron. I saw your post this morning but didn't get time to read
the articles you gave links to until now. That first one certainly seems to describe exactly what I have in my Phals. I think I need to get my hands on some Funginex next and see what that can do. I find it hard to believe I need to add one of the insecticides to the Funginex to make it work. I'll keep an open mind on that however.

Found these definitions on a website dedicated to fungus:
http://www.plant.uga.edu/mycology-herbarium/whatis.htm Macrofungus (macromycete) - The term macrofungus is used for large fungi that are readily visible to the unaided eye, such as the mushrooms, puffballs, and many cup fungi. Even so, detailed study of macrofungi must be conducted with the aid of a microscope, due to the small size of the reproductive structures. Microfungus (micromycete) - The term microfungus, meaning small fungus, is used for fungi in which a microscope must be used for even casual observation of the spore-producing structures. The majority of fungi are microfungi and their study requires experience with the use of microscopes. If this is the only meaning to the term and if it does not refer to a specific fungus or group of fungus than "microfungus" means nothing different from the term "fungus" as I generally see it used in this newsgroup and applied to fungual infections of our plants. Of coarse there are probably lots of fungus pathogens that do other nasty things to our plants besides cause rot. "Al" wrote in message news:...

I received two personal emails that lead me to believe that microfungus is
the name given to the fungus organism or group of fungus organisms that produce the symptoms you see in your first picture. One of the emails mentioned that the symptoms shown in your first picture, third picture and sixth picture to be those associated with mircofungus. I am guessing that while fungus which produce rots are microfungus by this website's definition, I think mircofungus, as the word is used here, is meant to exclude the fungus that we typically refer to when we are talking about 'rots' and to refer to the fungus that cause a specific type of symptom. If I get any more emails that shed more light on the subject, I'll let you know. If you ever had mites, the hort oil probably took care of them. Even a small mite infestation can be easily followed by fungus, bacterial and virus problems. They spread these pathogens and they leave lots of open wounds that these pathogens can use to enter the plant. Physan will not destroy any of these pathogen once they are *inside* the plant tissue. I have been informed that it is not systemic. It can only destroy the pathogens on the outside of the plants to stop them from getting in. Burn you whole collection. In fact burn down your house. ...and then wash hands with hot soapy water. You can buy a new house and start a new orchid collection tomorrow. "Steve" wrote in message t...

I've had it for two years now and it's actually two phals connected in one s/h pot. Anyways, Spring of '02 both phals started getting the yellow leaves with black pitting. When it first started it was sudden. Lowest leaf on both phals, then the next lowest leaf. Sunken yellow spots turning to black. I isolated it to another room and sprayed with funginex. That seemed to stop it. No more spread to the other leaves. ....................... Thanks for emerging from lurk mode. Your post adds yet more evidence that I should try Funginex. Steve |

I received two personal emails that lead me to believe that microfungus is
the name given to the fungus organism or group of fungus organisms that produce the symptoms you see in your first picture. One of the emails mentioned that the symptoms shown in your first picture, third picture and sixth picture to be those associated with mircofungus. I am guessing that while fungus which produce rots are microfungus by this website's definition, I think mircofungus, as the word is used here, is meant to exclude the fungus that we typically refer to when we are talking about 'rots' and to refer to the fungus that cause a specific type of symptom. If I get any more emails that shed more light on the subject, I'll let you know. If you ever had mites, the hort oil probably took care of them. Even a small mite infestation can be easily followed by fungus, bacterial and virus problems. They spread these pathogens and they leave lots of open wounds that these pathogens can use to enter the plant. Physan will not destroy any of these pathogen once they are *inside* the plant tissue. I have been informed that it is not systemic. It can only destroy the pathogens on the outside of the plants to stop them from getting in. Burn you whole collection. In fact burn down your house. ...and then wash hands with hot soapy water. You can buy a new house and start a new orchid collection tomorrow. "Steve" wrote in message t...

No, actually I didn't. I did that. I just didn't find any US companies selling it in the time I had.

Hi Steve,
You know back around 1990 you could not do a major show with out hearing war stories from other growers about their microfungus battles. It has been years since I have heard another grower even talking about it. It has been at least 5 years since I have seen it around here and I do see a lot of things. Going through my old supply catalogs it seems that Triforine (one of the chemicals used to battle it) has not been available for a couple of years now -- I did not even miss it or know it was gone. It looks to me as something may have changed. I think that the biggest change during this time period is that most of the growers switched from Benlate to 3336 as their general purpose fungicide. I can not help but wonder if 3336 is controlling microfungus, something that Benlate never did. A couple of good sprays with this as directed by the label might clear up the problem. Pat |

Really? There was about 5 pages of US supplirs when I did it. Try again.

Well I'm curious what the "cocktail" you used was. If you don't want to
reply to the NG, just reply directly to me... "Pat Brennan" wrote in message ... Ray, I am in agreement with Aaron, I think Steve has a microfungus. I was guessing that before I even saw the pictures. I have had microfungus on phals, I have cured it. But the only way I have successfully cured microfungus is using a cocktail of chemicals. Two months ago when I mentioned a cocktail Aaron replied with a post about not mixing chemicals under the risk of toxic precipitate and wrecked buffers. Not wanting to hear this crap again, I took my discussion with Steve out of the group. I just find it maddening that today Aaron is giving pointers to sites promoting chemical cocktails. Pretending that you know more then the chemical manufactures or the directions supplied with the chemicals does a disservice to this group. Is the label that comes with the chemical the "precise knowledge" we must know or is there more? If we follow the label are we still going to create toxic precipitate? If I am Steve, who or what do I believe? Chemical labels includes a section on compatibility and yes you better read them and follow the directions. Randomly mixing any chemicals is a dumb idea. But, when you take copper out of the mix, it seems that most of the chemicals I commonly use are compatible. I am not making that up, it is what the labels say, it is what experience has shown. Some of the more common cocktails are even marketed as a single product, Spectro and Banrot to name two. BTW, I highly recommend Spectro which is a cocktail of 3336 and Daconil as a broad spectrum fungicide. Sorry about the double post, I would blame my ISP but who would believe me.

I hope Pat replies to the group, as I have found this discussion *very*
enlightening. Thanks to Steve for bringing it up. K Barrett "Jerry Hoffmeister" wrote in message ... Well I'm curious what the "cocktail" you used was.
