Healthy gut biome for plants?

[JayneR13]

I recently subscribed to Northern Gardener, MN Hort's magazine focusing on planting zones 3-5. They have an article discussing a healthy plant gut microbiome as a solution to fungal diseases. Has anyone tried this? What do you all think of it?

From the article:

Gut health for our plants? Yes, please.
Supporting healthy plants means they
are less likely to be infected with pest
pressure or successfully colonized by
fungal diseases.
After two years of intense fungal
pressure on our tomatoes and all cucurbits
(melons and cucumbers), we have
applied our orchard cocktail of Cease
(Bacillus subtilis), molasses, fish and
seaweed emulsion, and castille soap
to our tomatoes, melons, cucumbers,
and fruit trees. We reapply about once
a week, or after a rain event. So far, it
seems to be keeping the fungal pressure
at bay this season.

This mixture was watered in as a soil feed? Or sprayed on?

From the picture I'm seeing sprayed on. I also found an article about molasses in the garden. Evidently blackstrap molasses contains a number of micronutrients. https://wisconsinpollinators.com/Garden/G_Molasses.aspx

I’ve been reading a lot of fertilizer lately and I’ve noticed molasses was also an ingredient.

I just started using CEASE & Reviatize on my Seedlings two seasons ago & as a foliar spray every 7 days after they are planted out.

So far many benefits on fruit & vegetables, on Tomatoes not so good.
Soil drench every other week wit5h Fish & seaweed fertilizer.

Marijuana growers popularized blackstrap molasses - I know it's high in K as well as micronutrients, but they touted it for "feeding the herd" ie the microbiome in the soil. I guess it can feed the foliar microbiome too.
Fish and seaweed is a good combo because the seaweed is high in K to balance the N and P in fish.

Cease is quite expensive ($100/gal on Amazon), but Serenade might be a useful alternative. The closest thing I can find on Amazon is Spectracide Immunox, but the listing doesn't say if Spectracide contains any kind of b(t).
