Ronde de nice continue to produce -- severe signs of SVB, wonder how long they'll keep going

Getting ~1-2 rondes per week the past few weeks, whereas I haven't seen a mature zucchini in quite a while. At least one or two of the ronde plants has major signs of SVB, with the vine hugely split open. So, I imagine their end is near, but given I haven't done any SVB control other than a little bit of egg monitoring last month (haven't done any BTK or other stem interference), I guess I'm somewhat impressed so far. Maybe they do have some little bit of SVB resistance, even if not fully SVB-proof. Will be interesting to grow them again next year to see if this repeats.
