Is Actinovate available to consumers up here?

cinnamon is supposed to work pretty well. I've also heard of using weak chamomile tea or diluted hydrogen peroxide. I've never used any before, so I can't attest to their success.

I have used cinnamon with good success. Just keep a shaker of it and use to sprinkle on the surface of the soil. Usually one application is good.
Last year I heard of the chamomile tea so I got a package at the dollar store and made it about half strength or a bit weaker. Used this to water the seedlings whenever they needed water. It also seemed to work fine as I had no problem with the seedlings I grew inside.

I used chamomile with good success. It's an inexpensive remedy. Also, remember air movement is important. I used to put a rotating fan on the seedlings for at least 1 hour a day. I never used a fungicide and had no problems. Also, I used to manually shake each seedling tray on occasion to help toughen the seedlings' tender stems. I grew thousands of seedlings indoors this way without disease before I got a greenhouse.

Dilute hydrogen peroxide is common in the greenhouse industry. Some plants may be sensitive.

Thanks to all for the useful info.
coolplantsguy, do you know which plants may be sensitive to peroxide?

No, I don't know off-hand. I've only heard suggestions to try it first on a specific plant before main/regular use.

Thanks coolplants guy
