powder mildew in greenhouse

[Noonin NorCal]

I'm thinking that if plants already have PM they already have PM, right? It's a systemic ailment for the plant and the spores are already floating around freely in the environment. I would get more air circulating in there to make sure it's not stagnant. I wouldn't worry about pHing your water since it's already nuetral and the greencure will bump it up anyways. You don't need any wetting agent with the greencure as it already has one in there. I don't know what the application rates are off the top of my head but just go with what is on the label. Greencure can and probably will burn your pistils some and maybe the tips of your fan leaves but that's better than having PM all over them.

What's up on some pictures too? I think that would help put things into perspective.

Im gonna try, I'm old school. and not new to technology etc. I'm only 32 lol. but i miss the pager days. I have an iPhone ill try and figure it out and snap some pics

has anyone tried Natura by bayer ?
It comes concentrated or premixed in a spray bottle. It's a natural bacteria that apparently attacks PM and a couple other fungus/molds.
I've sprayed some on a couple of my plants that have some issues and gonna see if it stops it in it's tracks like the lady at the garden store says it will.
the stuff reeks like some kinda weird sour wine and doesn't feel too good on the skin LOL

I haven't heard of that product before but what strain of bacteria is it in the Bayer product? Is it the same bacteria as Serenade?

Bacillus subtilis
possibly was serenade..... that sounds familiar. She said bayer recently bought this stuff and renamed it.
24 hours later my plants seem unharmed so will watch closely. Going to be foliar spraying with last application of bug b gon with canola. Should coat up the leaves nicely and buds should be free of any residuals by harvest time.

I sprayed 1 tablespoon per gallon of water with Green Cure. I think that is also the thing. I sprayed a while back before i even had fans and ran a dehu at night. The solution i sprayed then just sat on the foliage without much airflow and we already had a humidity problem overnight
