I first noticed the leaf problem a few weeks ago. Then a Squash the size of a small apple rotted on the vine. A few days later I noticed the baby squashes black & lifeless.
second pic of the leaves; sorry about the fuzzy focus.
eta;
I've been examining the pic's here http://aggie-horticulture.tamu.edu/publications/cucurbitprob...
To my untrained eye my problems don't look like any of the pictures...
I'm not having a problem with pollination, my summer sq, beans & cukes are producing like crazy.
eta again; I'm thinking there's two things going on, a fungus/bacterial issue & bug problem. This message was edited Aug 22, 2009 1:22 PM
yeah, only the female flowers are effected. That pic is of a female flower, all the rest are just like that. All the male flowers are fine. Plus all my cuks, sum sq, beans peas are over producing. I'm thinking a fungus. I'm gonna spray with a antifungle & see what happens.
I haven's seen a bug but I'm notorius at not finding bugs...
ALL your females did that? The flower in your photo looks like it never opened, so it can't be a pollination problem, and as you say, your other cucurbits are doing well, so the bees are doing their job.
Yeah, all the small female flowers are currently doing that. I've gotten 3 squashes before the illness started occuring. I did have 4 squashes but when the 4th was the size of an apple it rotted. No dark spots, just kinda withered & became opaque.
