beet curly top

[coloken]

I don't see much about BCT, but I bet Carolyn knows since she lived here a while. Any way, I think I ,or a few of my tomatoes have it. My guess is bacterial wilt or BCT. When I cut the stems and look for brown like to test for bacterial wilt, I find nothing. But then I am no expert. Individual plants first show wilt, top or whole plant first, never from bottom up. No yellow leaves until dead. Then worse and worse til dead. They talk about beet leaf hoppers, Do they mean common old grass hoppers?, which I have. Any other bugs spread it? It's taking one plant at a time usually takes a week or more to kill it , but took my orange 1 in 3 days.
Any thing else it could be? Plants just look like they need water at the start, try to recover, then die.

Beet Leafhoppers aren't just plain ole grasshoppers and they are the only insect vector for Curly Top. And the foliage, if it's Curly Top, looks very distorted. I'm sure there's some pictures in the Disease Forum from some of the links given there.

If it were Bacterial Wilt it would be a quick event with the plants wilting quick with GREEN Foliage and no way back.

And yes, a lot of sugar beets are grown in Co but the leafhoppers also have lots of other hosts that they hang around on as should be described in any disease site you go to.

When I was in CO I lived in Denver, on Locust, one block south of the 17th Ave pkwy and a couple of blocks East of Monaco Pkwy which takes you out to Stapleton Airport, eventually. And there were no Curly Top problems when I was there.

I'd expect it to be more of a problem, possibly, in more rural areas.

Thanks Carolyn, I will forget the curly top and go with the bacterial wilt. The plant very defiantly stays green all the way to death. Reading from
seems to fit. I just don't seem to see the brown sap bit but some time (many times) I don't do things right.

A short article on Curly Top from Oklahoma State University:
http://www.ento.okstate.edu/ddd/diseases/curlytop.htm

From their description, it sounds fairly easy to recognize.
