All sorts of theories abound about graft union orientation at planting. Bud unions can be positioned so as to have the prevailing wind "push" the varietal shoot towards the rootstock. Of course that's totally irrelevant when a nor'easter blows strong from the other side. I think this is less of a consideration for the stronger whip-and-tongue union.

The herbal constituents in pure neem oil are degraded over time by being subject to being "thawed" again and again. By which I mean going from a cool state (below 60F) where the oil solidifies to warmer temps where the oil liquefies. Storage at higher temps wouldn't be helpful but one day in summer heat doesn't undo potency. Far more important is pouring into batch size contaiby Michael Phillips - Spray Nuance
Some of you know efforts are underway to restore integrity to organic certification in the hands of the USDA with a supplemental label. The Real Organic Project is grower-led and harkens back to original intentions that the word "organic" represent healthy soil, healthy food, sound ecology, happy animals, and yes, viable farming.

I'm going to ask you to clarify a couple points, Tom, in hopes this will give others enough information to respond. The notion of "escaping disease" by removal of a tree to ground level --and thus a reboot provided the root system sprouts anew -- demands we understand deep systemic reality versus biological and nutritional deficits within a given growing system.

Liz, I'll go with the Triple Threat package (three species) from Arbico as I don't really know the full range of depth of AMF pupae. This spring application might equally be valid for European Apple Sawfly, provided it's a few weeks prior to bloom. One question I've always had as regards parasitic nematodes is if effectiveness will be higher at the larval (entry) stage or equaby Michael Phillips - Bug by Bug
Three points, Liz. No, actually, four . . . Karen and I are glad to include the upper Midwest in the AMF matrix! Which obviously is a real thing in your bioregion despite such kidding. Lodi with no AMF issues in 2018 tells me this is a case of delayed emergence. Thus why I look to the yellow sticky card test for zeroing in on actual timing at the start of the AMF season each year. In theory, sby Michael Phillips - Bug by Bug
Apparently, we're the only growers in this discussion forum dealing with AMF, Karen. From New Hampshire to Washington, no less! So goes the pace of mutual learning by sharing approaches and varietal observations.

Intense pressure from apple maggot fly (AMF) once again this year was made all the worse by having a relatively light crop.

Minnesota genetics are at the heart of Honeycrisp susceptibility to apple maggot fly. (Which in truth may be the Malinda apple from Vermont used in the Minnesota breeding program.)

I agree with your horticultural observations, Pat. It looks like the potential fruiting wall created by dwarf trees planted two to three feet apart may not be supported by a trellis. My guess is little was done with mycorrhizal inoculation as well, and fungal connection more than anything else is what it will take to establish any plant community on a bulldozed mine site.

I'm sure feeling the need to call in. Our orchards are on varied slopes yet I've found a way to traverse my way through the trees on a mid-size tractor.

Glad you brought David Johnson's work to more grower's attention, Karn. More than a few organic orchardists regard compost merely as a means of replenishing nutrients when the full virtue lies in facilitating microbial diversity.

I've been thinking how we in this forum might best post lengthy sharing of research and speculative ideas.

The original question here pertains to an "organism ferment" to get microbial byproducts that in turn knock back pest populations and/or prove antifungal or antibacterial.

Appreciate all the insightful thinking behind homegrown EM, Karn. Some growers will experiment here and some will not. Both are fine choices based on the busyness of our lives.

You'll find some of the answers you seek in a previous thread on activating EM in large batches, Harrison. Long term storage (beyond 60 days) where microbe populations remain relatively stable is enhanced by addition of humic acid, one percent by volume.

Others have started reporting "summer dieback" in various places, specifically in Maine, Vermont, and downstate New York.

What you don't want is for living larvae to reach soil to pupate. Sitting in buckets for a month or so probably does them in as I imagine the bulk of those fruitlets begin to compost in situ.

Each pathogen has a strategy by which to gain access to plant tissue and thus cause infection. The "aesthetic fungi" that cause sooty blotch and flyspeck feed on the waxy plant cuticle.

Nettle is a tonic herb whereby herbalists refer to its array of phytonutrients as good for health in general.
