Protecting Crop Yield Focus of Extension Field Day near Wall Lake


AMES, Iowa – Protecting crop yield will be the focus of a field day organized by Iowa State University Extension in Sac County on Aug. 27, from 9-11 a.m.

“This field day will discuss crop protection programs related to weed, insect and disease management,” said Mark Licht, ISU Extension field agronomist in Carroll who is coordinating the field day.

The field is located north of Wall Lake on 340 Street, one-quarter mile east of the intersection of 340 Street and Needham Avenue. The field day is hosted by Crop Protection Services, Wall Lake, which is a partner in Iowa State University’s Corn and Soybean Initiative. BASF is sponsoring the event.

“ISU specialists will discuss issues that can negatively affect or enhance the effectiveness of herbicide, insecticide or fungicide applications,” Licht said. “They will also discuss timing applications to achieve the best possible results.”

Alison Robertson, ISU Extension plant pathologist, and Erin Hodgson, ISU Extension entomologist, will discuss data from 2008 research trials comparing calendar-based applications of pesticides with IPM-based applications.

“Several agribusinesses are offering growers pest management plans that include a calendar-based, co-application of fungicide and insecticide,” Hodgson said. “We’ll also discuss scouting methods and thresholds used for making management decisions.”

Bob Hartzler, ISU Extension weed specialist, will discuss short-term versus long-term weed management goals.

The field day is free and open to the public. Refreshments will be served starting at 8:45 a.m. For more information, contact Mark Licht at (712) 792-2364 or by e-mail at lichtma@iastate.edu.
