So let me preface this, Alan, by saying that I defer, in general, to your much greater expertise. Iām just describing my own local observations and deductions. Iāll try to give a little more detail below so that people can evaluate my thinking for themselves.
So, to be a little clearer, my guy doesnāt particularly advertise his fruit as being no-spray. Like, thereās no sign saying, āNo Spray Peachesā on his stand, just a sign saying peaches however much a box. (Along with apples, raspberries, etc.) I happened to read a piece about his familyās orchard online and it mentioned in passing that they were growing their fruit no-spray. Assuming that the information came from him, Iām inclined to believe it. (I think I may have asked him about it once, but I canāt exactly recall.)
Why am I inclined to believe it? Partly itās that I consider him to be a stand-up guy, based on our interactions over a number of years, so I donāt think he would intentionally deceive someone who asked about his growing practices. (And for what itās worth, his family has been running their orchard since the 80s.)
Partly itās because he doesnāt particularly advertise the fruit as being no-spray, nor, from what I can tell, does he charge higher prices than local peaches generally go for. Lower than some places, in fact. So, while I understand where your skepticism is coming from, this isnāt a case of implied-purity-at-a-premium-price. (While this is partly speculation on my part, Iām guessing that he MIGHT be growing no-spray partly to minimize overhead, because it seems like a minimum-overhead operation all around. Setting other considerations aside, he might have concluded that heās better off growing the peaches he can grow without spraying than he would be spending the money it would take to spray what would remain a marginal crop climate-wise.)
Partly, itās because the quality of the fruit seems consistent with what I understand to be the challenges of no-spray orcharding in New England. Like, itās visibly less pretty than fruit from local orchards that practice IPM, which from what I can tell, is what most of the still-pretty-small-but-comparatively-larger places around here do. And sometimes, when the weather doesnāt cooperate, there may be no marketable fruit at all. Still tastes good when itās there, though.
And partly itās because the possibility of growing stone fruit without spray on a SMALL scale seems consistent with other local evidence. For example, our next door neighbors had a couple of peach trees for many years. As far as I can tell, they did virtually nothing with the trees: didnāt spray, didnāt thin, largely didnāt prune, and the trees (of a variety they didnāt know) were placed in a less-than-optimal spot for sun and ventilation. Nevertheless, on years when they didnāt get frozen out, the trees bore a pretty sizable crop of fruit, much of which dropped into our yard. As far as I could tell from picking it up off the ground, the fruit was largely sound (not rotted), except for the chunks that the squirrels had taken out of it.
I know several other people around the neighborhood who have peach trees that they do just marginally more to take care of (still not spraying), and when the weather cooperates, they get a good amount of fruit that they appear to enjoy. Is the fruit as good as the fruit that you or Olpea grow, or as good as your customers (of different kinds) might demand? Very doubtful. That being said, itās not super uncommon for people where I live to grow not only no-spray but to all appearances minimally cared-for stone fruit that they consider worth growing (granted, of course, that itās not super common for people to grow fruit at all).
Considering that my Fruit Guy is considerably more skilled and knowledgeable than my neighbors (and letās be honest, me), I find it plausible that he could be growing the fruit that he grows, on the scale that he grows it, on a no-spray basis.
All that being said, New England is definitely not California, and from everything I understand, peaches and other stone fruit are not a super reliable crop here. I would imagine that an effective spray program could mitigate some (not all) of the hazards involved. However, my personal observations suggest that in this part of New England, spraying is not absolutely necessary to grow fruit that some people would consider worth growing, eating, and in some cases paying for. (Understanding, again, that we are talking about growing on a small scale and for what we might call a sympathetic audience.)
