Re: bacterial wilt

Thanks Vince. We had a couple of days of good sun and heat so maybe you're right. I found it strange that it was only on new growth (leaves 3-4" wide).

I also sprayed lime sulpher on the plants this past weekend. Last year I found it to be the only thing to control the powdery mildew. I wonder if this was bad for the new growth?

thanks
Dave

Try placing shade cloth over the new growth.  It sounds to me
more like old-fashioned sun burn.  If an AG is heavily
fertilized, it will grow so fast that the new growth become
very  sensitive to the sun. Shade cloth gives new growth a
chance to harden up before the sun fries it.

Bacterial wilt first causes mature leaves to wilt, then whole
sections of vines to die.  See:

If the plant truely has bacterial wilt, you should probably
pull the plant and burn it, but it doesn't so don't do
that.....

I think I have a case  of bacterial wilt. My new growth has
brown,
translucent patches on the leaves. I saw one cucumber beetle
on the
weekend and one tonight.

I sprayed with liquid Sevin on the weekend and organic
rotenone
tonight. Anything else I should be using that is available
here in Canada?

thanks
