I disagree with the application of a fungicide at the time of deflasking. The flask is a sterile environment, so the seedlings aren't carrying anything, and fungicides are for treatment of fungal infection, not offering preventive value.
If you're looking for prevention of disease, and enhanced growth and survival rates, an ex-flask bath in Inocucor Garden Solution, followed by regular, periodic treatments is the way to go.
Some will view my comment as being a blatant ad, but I sell a great deal of the stuff to commercial hybridizers, who swear by it. The late Holger Perner, who struggled to get Paph. tigrinum to survive to maturity more than 5%-10% of the time, got that up to over 85% using the product.
I will add that, being retired, I had considered shutting down First Rays altogether, but the folks at Inocucor asked me to keep selling it. At my current price, which includes free shipping, I make very little on a bottle, so in reality, at this point I'm making it available, not making money.
