I'm in my second year of a veggie garden. Last time SVB got my zucchini and squash plants. I noticed early on that the main vines are cracked/split but I haven't seen the moths and I've been treating the plants since we moved them outside. I didn't think it would be SVB so soon since these cracks showed up so early. I can't figure out why else the vines would be split, but I don't notice a lot of frass or other signs of SVB we had last time. The plants aren't wilting yet and are getting their first zucchini. Does this look like SVB?
