White Mold Infestation!

[Hugorchids]

On my way back from out of town, I check back on in my greenhouse and noticed there are white molds that are growing on some of the plants. They literally seems to grow overnight! I don't know if they are harmful or not, so far I don't see any of the plant tissues showing any symptoms. I took some snapshots below. What could they be?

Sounds like you had better disinfect the greenhouse.

I HIGHLY recommend Zero-Tol RTS for that, as it can be used on the floor, structure, benches and plants with no trace of damage.

Physan is another good alternative, but some plants can be sensitive to stronger concentrations.

pics are up now, had to reduce the size to upload to OB.

What have you used on the plants? That's a lot more mold than I would ever expect to see, unless you've applied something the mold favors.

Have you treated for snails lately, it look just like the fungus that grows on wet snail bait.
