Look at my July 4, 2004 Diary page.
Is this Bacterial Wilt?
It started on the 1st and is only on a couple of leaves, now on several secondaries about two feet in from the tips of the secondaries. Admire was drenched in 21 days ago and Isotox foliar sprayed 18 days ago. Since then the only thing sprayed on the plants have been molasses, seaweed, fish and 36-6-6. The 36-6-6 and fish was sprayed 2 weeks ago and not since then.

I did notice more than normal amount of cuke beetles on the mentioned leaves. I applied Admire in the gravity Irrigation and later dusted with sevin on the leaves to get quicker results. Any thoughts??????

No this is not bacterial wilt it is probably the sevin that burnt them especially the younger leaves.

I get the same thing on my plants. I think it is burning on the leaves from the sun without moisture. I have been misting durring the hottest part of the day (12-2) with a regular garden hose. The burning has gone away and the plant seems to get over the wilt look.

Thanks for the response.

Sevin was applied for the first time this year, today.

I do not think it could be from the sun for only a few leaves in the same location on each secondary are affected.

There are a few holes in these leaves and from these holes the leaves turn dark green/black (the wilted part of the leaf) then on the outer edges it turns to a dry brown.

I have some of the same thing. Im pretty sure it happens to new growth leaves when the conditions are just right... hot, and sunny. I believe it to be sun burn. Just my opinion.

I believe it takes 6 weeks for wilt to show up, and it only takes 1 beetle that is infected. I have been seeing wilt from heat the past few days. Doesn't hurt to run the misters or sprinkler for 5-10 minutes to cool the plant down. It seems to me, that with bacterial wilt, the plant seemed to wilt later in the day, and would not respond to an overhead sprinkling.

Check this site out. http//www.oznet.ksu.edu/dp_hfrr/extensn/problems/bacteria.htm It is a simple test to see if your plant is infected. Thanks to " the Borer" who posted this link in another thread.

With responses here and emails most concur that it is not wilt but sunburn. I did the B. Wilt test as mentioned, but from another site and it was negative.

Thanks for all responses.....Tom
