Since your reply, there's been a lot of discussion about vining squash (Hubbard, etal). I forgot to ask, when you spray, do you have to spray the underside of the vines/leaves? My Mom always use to do that and it's quite a pain.
I tried to grow Zuchetta and butternut on a vertical panel (cattle panel) trellis, which didn't work too well. Next year, I'll convert the panels to hoop or arch trellis, like you did for your beans. The Blue Hubbard, I'll just let run over the ground like others do (and spray).
