Flea
Beetle Outbreak in Iowa
Compliments of
Agronomy Services Department
Reports from Iowa indicate a major flea
beetle outbreak this year. This is cause for concern because flea
beetles spread Stewart's Bacterial Wilt disease in corn. While
Mycogen hybrids have been bred to resist Stewart's wilt, major outbreaks
of flea beetle should not be ignored. This problem alert is being
developed as a resource of information on the flea beetle and Stewart's
Wilt. If you have further questions, contact your local Mycogen
agronomist.

Other Resources on the Web
There are some excellent resources on the
internet regarding flea beetle and Stewart's wilt. In 1999, the
University of Illinois put out an excellent article on flea beetle.
Here's the link:

Lastly, Iowa State has one of the best
publication's on Stewart's wilt. All aspects of the insect and the
disease, including CONTROL,
are discussed within. Here's the link to that:
