Phyton is copper based. I may be wrong but Physan is not.
"Diana Kulaga" wrote in message ... Just my 2 cents here. I'm a firm believer in Physan, but if I were growing inside, I'd rather put up with the smell of bleach for a few days than the smell of Physan. And even outside, we occasionally wash down the grow areas with bleach. As far as copper based products are concerned, I wouldn't categorize myself as a *tree hugger*, but I imagine that any of us who ardently love orchids, or any other plants, have at least a modicum of concern about the environment. Copper has its place, but it's one of those elements that does not break down in the ground. From what I know, it pretty much stays where it lands. Chemists, correct me if I am wrong. Also, if you grow Dends, be very careful with it. Dends will drop their leaves if treated with a copper based product. Semi hydro works wonders for some of my plants. I often wonder why I haven't bitten the bullet and gone for it on a wholesale basis. Potting medium? Orchids are not as fussy as we think they are. But, you need to adjust watering, etc., based upon the medium you choose. I have been growing Catts and Dends in plain old river rock or pea stone using plastic pots for about 5 years. No problem. But I tend to *underwater*, so I am gradually going to Aliflor or Primagra (sp?). Our Phals are in Aliflor now, for the most part. We got tired of root rot. The exceptions are small plants which dry out faster; those get spaghnum. For the plants that I have in a CHC mix, we need to take into account how much water that stuff wicks up - a lot! There are as many ways to pot an orchid as there are people who grow them. Two recent speakers at our society meetings illustrate this. Jeff Adkins (Adkins Orchids, Fort Lauderdale) did a demo on repotting Dends. He used CHC 'plugs'. I would hesitate to use them for Dends; too much water retention during our rainy season. But he grows great plants, so who can argue, except that he has a more controlled environment than we do? And Michael Sinn (Canaima Orchids, Ellenton, FL) is an undisputed expert on Venezuelan Catt species. I bought two plants from him, a mossiae and a leuddemanniana, and both are in baskets with spaghnum. That won't work for my grow area, so after they bloom I will repot them into something more suitable for us. Hmph. I guess that was a dollar's worth, not 2 cents! Diana |

I can't say I *prefer* either of them, really. It just seems to me that the
bleach odor dissipates more quickly than the Physan, which I can smell for a week. And that's outside! Hmm. Men like Physan, women like bleach. Well, I'm not a natural reddish haired person, for whatever that's worth! Diana "V_coerulea" wrote in message ...

No, Physan is not copper based. That's one of the reasons I use it. We have
a bunch of Dends. Diana "Al" wrote in message ... Phyton is copper based. I may be wrong but Physan is not. "Diana Kulaga" wrote in message ... Just my 2 cents here.

Well I like Brandy & hate beer!
Also use a bottle for my hair. *g* Not sure about the gender thing, I use both but have not used a bleach/water mixture directly on my plants! (Although some of them look like it!) I use Physan a lot. -- Cheers Wendy Remove PETERPAN for email reply Diana Kulaga wrote: I can't say I *prefer* either of them, really.

Ah ha! now i remember why i wasn't too eager to use physan or phyton: "corrosive" "permanent eye damage." i knew there was some reason i was staying away from them.... the copper octanoate and neem are only considered irritants. well, guess i'll be spending the weekend repotting. oh joy. (only about 15 plants fortunately.) or i may say the hell with it, spray them with neem, take my chances, and if they die, they die. feh. :) as always, thanks for the very informative discussion. --j_a |

Physan is not a corrosive. You may get permanent eye damage from squirting
the concentrate into your eye. But you'd get that from bleach and Neem as well. So best not to squirt anything into your eyes. If you're still fearful, use goggles which is a good precaution anyone should take when using sprays. For other things like tools, you can let them sit in Physan for a week and they won't show any rust or other damage. A soak is best for the kind of problem you have. Sprays just don't penetrate deep enough into the tissue to eliminate the bacteria or fungus. You generally don't have to soak the whole plant, just the cut or infected area. Some bacteria species (especially Erwinia spp - Brown rot) can become systemic and require a whole plant soak. Hope you can stop the infection before it takes all.

It needs to be cleaned, wiped down from top to bottom. Now I would move everything, saucers, trays, pots, tags etc., wash in a bleach/vinegar solution 1/2 cup ea. to a gal of water. Repot everything before returning plants to the growing area. I spray any plant I repot with Physan/water. Not sure of the best potting mix for indoors but it seems like most inside growers water too often! I would use some horticultural charcoal in the mix. Lots of luck, With Rot - I just water with H2O2 until it is fixed. Either gone or keiki to grow. The bit of rot that gets hit the second time you wash it down was not the same as you hit the first time. But I also use Physan in the gh and only spray with bleach if I can stand to loose the clothing I am wearing to bleach spots. Good Luck. |

Oh gosh. Now you've done it. This is gonna hurt. I bet it's gonna be even
worse than the time Mick said, "Never touch the cotton in the vent on the flask...no matter how much you want to." "V_coerulea" wrote in message ... So best not to squirt anything into your eyes. |

JA: One thing comes to mind that I haven't seen mentioned in the other
responses -- root rot should not be spreading from pot to pot. Are your plants so crowded together that you are splashing water from one pot to the next, when you water? Or are you using a communal bucket to water by soaking?

no, actually they're not too close together, and they each get watered
with fresh water (pots are put on the dish drainer tray and watered thru, and they sit for a few mins, then get put in the sink to drain out, about 4 pots at a time. water from drain tray is dumped between pot sets. maybe no more of that sitting in communal water, even for such a short time.....) i'm assuming what's happening is that something is becoming airborne and lands in another pot. so far it's only been three, but i'm worried it might spread, which is why i was looking for a preventative spray or something.... two other plants (both from the same nursery... hmm...) have something *else*. looks like white chalky stuff. i've got this little collection of plants on a table in the corner, in quarantine.... :-) --j_a |

Out of show mode lurking for a second.
"AND my african violets have powdery mildew" -- This is the problem. Powdery mildew is a form of botrytis. My books are under 8 weeks of stuff so I can not tell you which kind, but I do not think it is the same botrytis that causes whites Phals to freckle before a show. But when ever I have a powdery mildew problem in the AVs or streps, crud growing on the orchids is soon to follow. It is bad stuff, moves quick and can cause a lot of damage. I hit everything with a systemic fungicide and then mop up with Phyton. In addition the AVs must be cleaned up to rid them of the visible powdery mildew. The fungicide will trash the AV flowers and buds, so you might as well remove them while cleaning up the plants. If you go this route, take all of the plants outside to spray them. While they are drying spray the growing area down with physan.

Found a book before I was corrected, in violets gray mold (not powdery
mildew) is Botrytis cinerea and is bad stuff. Pat "Pat Brennan" wrote in message ... Out of show mode lurking for a second. "AND my african violets have powdery mildew" -- This is the problem.

AV's are getting weekly sprays with neem and the copper octanoate
(which i will probably stop using, given its lingering-ness in the environment). they've been put in their own little quarantine on another table, but all the plants share the same air supply and air movement in the living room, so there's only so much to be done, i'm afraid. :( thx for the heads up though. :) --j_a |
