Has anyone used this with success? It's the first I've heard of it.

I've come back from a bit of a hiatus.
As a belated response I have not tried this but Bacillus amyloliquefaciens D747 is sold as a bio-fungicide under a number of different brands besides Southern AG, You'll see it sold by under Monterrey, Bonide, General Hydroponics and others maybe.
I think it was originally marketed and still is by Certis as Double Nickel.
It is rated effective as a preventative against a number of common fungal pathogens on leaves and roots but not all of course. If it was rated as effective against Septoria on Tomato plants, I'd be all over it! Sadly its not.

Here's some more info you can read about this specific bacterium:

Glad to see you back Ray.

Welcome back, Ray. Thanks for the information. Septoria is indeed a big problem, but so is gray mold, so I'm wondering if this might be effective in preventing that. Also, eliminating mildew on cucurbits would be great, too. Might have to give this a try- thanks for posting this, Linda. Hopefully someone else can report with results from last year or before.

According to the label it is supposed to control Gray Mold (Botrytis)
Botrytis has been a rarity in my garden, so I've never had to deal with it much.

The label even states it does control the "Septoris species", but there are a large number of Septoria species, how effective it is on Septoria lycopersici on tomato I don't know. It might be worth a try myself, God knows I've tried every other biological control for Septoria without good results at control. Even with some suppression Septoria always won out in the end.

Thanks, Ray, I did see that. Gray mold is a yearly problem in my garden because dark tomatoes are the faves around here and we have lots of humidity and dew because of our location; so much so, that I'm hesitant to believe that it will actually work. I also really dislike the job of spraying but will probably give it a try. Certainly won't break the bank either.

I use it yearly and it is very effective when used in rotation with other fungicides.

What diseases have you found it effective on?
I know Bacillus amyloliquefaciens is closely related to Bacillus subtilis so it has a high tolerance to chemicals. What fungicides have you used it in rotation with?

I use it in rotation with copper, BA & potassium bicarbonate. I mainly use BA for root issues as a drench.
