Ewing Field Day Set for September 10
Dennis Epplin, crop systems educator

The Agronomy Tour at the University of Illinois Ewing Demonstration Center is set for Thursday, September 10, at 9 A.M.

Vince Davis, U of I Extension soybean specialist, will be discussing
the topic of High Yield Management for Soybeans. Steve Ebelhar from the U of I Dixon Springs Agricultural Research Station will present
information on the latest wheat research. AgStrong officer Robert Davis will offer details on canola marketing opportunities.

Other field day topics include Japanese beetle research, and the history and contributions of Ewing Field.

Representatives from Qualisoy™ will explain opportunities for growing healthier soybeans and taking advantage of marketing opportunities.

A complimentary lunch will follow the field tour.

This year marks the centennial observance for Ewing Field. The
University of Illinois started research and demonstration work at Ewing
in March of 1909. The center’s new multi-purpose storage/education building will be showcased, along with recognition of donors who
contributed to the construction of the building.

The Ewing Demonstration Center is located approximately 12 miles northeast of Benton. From Illinois Route 37, turn east on Ewing Road and watch for signs. If weather conditions are questionable, call 618-242-9310 before traveling to the field day.

Managing Volunteer Corn
Jim Morrison, crop systems educator

As more glyphosate-resistant corn hybrids are planted, so has the prevalence of volunteer corn in soybean fields. Volunteer corn can reduce yield and crop quality of soybean, and research has raised the question of the potential impact volunteer corn may play in the resistance management of western corn rootworm.

Vince Davis, University of Illinois Extension soybean specialist,
suggests these fall strategies to help minimize volunteer corn in soybean fields next season.

• Make note of the pressure of volunteer corn in soybean fields and determine how dire changes in harvest practices need to be this fall in regard to timing and settings.
• Make note of corn fields that you may expect will have more
  volunteer corn next year because of “downed” corn or dropped ears. Next, adjust your crop and/or herbicide plans as necessary to possibly avoid an additional herbicide in your post-emergence program in those fields.
• Assess the density of volunteer corn early in the growing season next year. Volunteer corn does not look as “thick” early in the season before it starts to tower over the soybean canopy.
