@moose71 - For clarification, did you wrangle with Michigan? And do you remember when and with whom?
I do know there is a U-pick farm in Kent County that has red, black, and white currants. And I’m pretty darned sure that she doesn’t have Rondom. (I asked once - I think they are Red Lake?) So somebody got them to unbend about it once.
In my day job as a vet, I do interact with MDARD. I find that success or failure in getting them to unbuckle their bureaucratic belt a notch or two depends on A. if what I’m asking is reasonable, B. that I can successfully argue a lack of risk, C. I am polite and professional about the request (and often just a bit self-deprecating. A bit of ego-stroking doesn’t hurt), and D. that who I am dealing with is susceptible to A-C.
I actually understand their concerns re: WPBR, but I do agree with you that the bulk of the evidence suggests that nuking the ribes from orbit doesn’t have much effect as a control measure. Past experience with MDARD, however, would be that “you’re doing it wrong” is not a good approach. Goodness knows that the Emerald Ash Borer quarantine was pretty ineffective.
It must also be admitted that industry voices are just louder than individual would-be fruit growers. In this case, the lumber industry. My mother is quite disappointed that she can’t get a Ka-Bluey blueberry plant. I’m guessing that the one source for it doesn’t want to bother with the phytosanitary certificate. And the blueberry industry pushed hard for that lockdown. Again, not without reason, but it does sort of pinch the little guys.
