White snow mold

[Atzau]

Hiya all,

Just happened to notice what looks to be some white snow mold on the media of one of my phals. Of course it also happens to be one of the two phals I have that is in bud.... Just opening the first two of 7 flowers in fact. What do you guys think....Repot now or later? And how should I clean up the roots during the repot?

Can you post a picture?

Contact Inocucor in Montreal - you can request a sample of their biological pond treatment at their website - it's chemically the same as their Garden Solution product, but they cannot register it as a plant or soil amendment there, as it is in the US...

It's basically a plant probiotic, but it will also kill the molds.

Thanks for the tip ray, I'll see if I can get a sample!

Would physan be suitable for this sort of problem?

physan would work fine..you have to either remove/replace the media and soak it down for a few hours when you have the white mold spores in it. Otherwise as a preventative measure you just mix it up and hose down plant and all according to the directions.

physan 20 is good for many orchid things like sterilizing the tools, potting benches, pots etc etc.

physan also works on the green algae/black mold you might have on the walls and floors of greenhouse type environment.

"Triple Action Consan 20" is how its made available to us n the state of Texas.

I have used Physan for years, but am moving away from it.

Physan is a marvelous killer of pathogens, but it also takes down beneficial microorganisms. My first move - and still my "go to" if there are major issues - was the use of BioSafe Disease Control. It's a stabilized hydrogen peroxide product that has shown absolutely no phytotoxicity (unlike Physan with some dendrobiums and more sensitive species), is very effective at killing pathogens and algae on contact, yet somehow is less damaging to "good bugs".

Stage two was a drastic reduction in the amount of fertilizer I apply. Not only has that reduced the algae bloom (the low P in K-Lite also contributes), but as the plants are sturdier, they are less susceptible to rots in general.

Then, about two years ago, I started regular application of plant probiotics, after seeing what they did for me!

Overall, I see almost no rots occurring, and my plants are growing and blooming better than ever.

Ray, what are plant probotics please? What do they consist of?

[Ray]

Bil, in my case, I'm referring to a commercial product originating in Canada that consists of live cultures of beneficial bacteria and yeasts. Basically, they set up stable populations that compete directly with pathogens, as well as dose the plants with metabolites that stimulate their growth and resistance to pathogens as well.
