Bacterial streak--- Corn

[sw363535]

Zanthomonas,  is what I been told

Showing up in specific varieties....  Anybody had any experience with this...

It got worse as the plant went reproductive...

We are told nothing can treat for it.

What will yield bump be??

Zanthomonas ?? Looks more like Northern leaf blight to me - And that can be treated - I only thought that Goss' wilt was non treatable - But I NO expert either - lol btw sw - I sent you a pm

[elcheapo]

Try a X rather than a Z

Since it is a bacteria rather than a fungus....
Not antibiotic registered for field crops that I
Know of.

Sorry

You needed the corn crop to make up for the wheat.

Stewart's Wilt??  Seen any little black bugs around?

More common in sweet corn but apparently some varieties of commercial corn are susceptible.

Here is Iowa State's recent release as of 26 August.

It does look like GLS but is bacterial, so like Goss's Wilt.

Originally found in South Africa.  How did it get here?  Not much know about it yet.

Thanks Jim for posting that up -  I had samples pulled from one of my fields to be checked - But was only given limited info on what they were looking for -  now I know that they are seeing just how far it has spread to . ( If 's made it to Indiana )  I have heard that it seems to be found more so in irrigated corn - 

and may effect some variety's more than others .

I read on Pro Farmer tour , that the yield check's in the irrigated corn was not as high as they thought it would be - Wonder if this is the reason ?

sw - Are you seeing it more in the fields with a humidifier or a varity ?

It is variety related in this area.  Rep. said pioneer has had it in two varieties for the last two years at the local research farm..

"Not bad enough to be a yield issue"

Sorry I been a little busy....  We had a person who used to contribute here occasionally show up with a son to help us through this harvest so I am getting a little more opportunity to read.......... Thank you bugeye... I believe that was his entry name....
