Entomologists from five north-central states are planning a corn
rootworm management workshop to be presented on February 4 and

Results from the Annual Fall Survey for Second-Generation
European Corn Borers
The traditional table of European corn borer larvae and
percentages of infestation by county has been replaced by a
web-based PowerPoint slide set. In 2004, European corn borers
were most noticeable in Illinois by their absence. This doesn't
necessarily mean that we won't experience economic infestations
in 2005, but we do know that the population overwintering will
be very low throughout most of the state.
Review of 2004 Soybean Insect Management Trials
Data are being analyzed from two soybean trials targeting the
management of the bean leaf beetle and another targeting control
insect pests in soybeans. The hope is to gain insight into the
possible yield increase with the use of systemic nicotinoid seed
treatments or application of insecticide + fungicide, even in
the absence of economically threatening insect levels.
Illinois Soybean and Corn Diseases in Review--Reports and
Observations from 2004
Despite high average yields for both corn and soybean across
Illinois, diseases affected stand establishment and yields.
Diseases of soybean and corn that were common in Illinois in
2004 are reviewed. Vigilance in management can do much to reduce
the effects of disease |
