Real experience here! Valuable nuance too.

And so questions must naturally follow.

 

What I’d like to hear from Doreen is a few more details. I seem to recall you live in Wisconsin, right, so that means a goodly share of apple scab, perhaps cedar apple rust, and the summer diseases to contend with in the orchard. What are some of the apple varieties you grow? And more specifically, what’s the timing of your neem seed oil application(s)? Is this the Trilogy formulation? Are you using any other fungicidal materials? Or compost teas? And lastly, how does your most disease susceptible variety look at harvest time?

 

As I understand it from long discussions with Don Chapman, owner of Bio-Organics, fungicide drenches do the most harm to mycorrhizae in the soil. Those sprayed on trees don't have as much impact. I try to use fungicides like neem seed oil that act as barriers to fungus spores, as opposed to fungicides that are taken up by plant cells.

Doreen Howard,

who inoculates everything with mycorrhizal fungi and has the big harvests and healthy plants to prove the power of mycorrhizae.

 

I totally get it that micoorhizae are invaluable allies in the orchard. I’m just more inclined to induce local culture for field-wide application over paying someone $100 for microorganisms in a jar.
