RE: bacterial wilt

Has anyone encountered sun burned leaves in there patch? Vince's note on
sun burned leaves seem to be what's been happening to me. It's been in
the mid 80's (Orange County, Ca) the thermometer in the patch has been
100 deg on the ground. Does this mean covering the plant by noon to
block out the sun and watering to cool down? My only question would be
doesn't anybody work for a living?

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
