Problems with squash and cukes Help

[queensgrt]

Squash leaves; have gotten a few beautiful squash and now this



and the cukes on the same trellis

Haven't seen bugs or spider web type things, but I'm a newbie so am asking if anyone recognizes anything here and do I need to dump it all and Clorox my boxes or what?  As alway, thanks in advance; I'm so disappointed as they all looked so good two weeks ago

The older leaves on my zukes look like that and worse.  I give some supplemental nutrition and spray with chlorpthalonil (fungicide) and move on to the next problem.

My squash and melons looked like that last year.  I took some leaves (in a baggie) to my nearest favorite nursery and they sold me a fungiside.  Most of my leaves were goners by that time.

I'm going to notice and act sooner this year.

Are your leaves crisp and crumble when you scrunch them?  Mine were.

My squash and canteloupe leaves are starting to look like that.  I have been spraying with a fungiside but it rains almost every day ( at least for the past two weeks) and it seems that I need to spray everyday because I am afraind the spray is getting washed off.  Can you over do the spray?  I have many flowers on all the plants and hope for some fruit and veggies.

Fungicide is a preventative I don't think it's any good after the plant
has contracted wilt, etc
I use it weekly

My cucumbers looks identical, but maybe a little worse... I have been trying to battle it for a few weeks now and it doesn't seem to get better.  All the new growth looks great though... and I'm still piccking a few cucumbers a week.  My sqaush are starting to look the same, too.... if you come across anything that helps, please let us all know.

I am spraying every couple of days with Daconil.....and we have had a ton of rainy damp weather. I have no powdery mildew and no ratty looking cukes and squash leaves. Once you see the fungus, the fungicides won't be as effective. You need to accept the fungal problems or believe in a preventative program.
