Lower leaves are wilting and there appears to be internal spots inside the vines of my cacuzzi (Italian summer squash). Going past those affected lower sections the vines are prolific and lots of flowers, but I don't detect any fruit yet. I Don't know if there is any connection to my problem this season with squash borer which desimated my zuccini, yellow, and my butternut squash plants. There does not seem to be similarity in comparing its visual affects.
