Soybean Aphid Management Update

Virgil Schmitt, Extension Field Agronomist, Southeast Area

Problem Statement: 

Since its discovery along the Illinois-Wisconsin border in the summer of 2000, the soybean aphid has been a sporadic pest of soybean, generally causing concern among dealers and producers during odd-numbered years for reasons that are not totally understood.

Programmatic Response: 

Iowa State University cooperated with the University of Illinois and several other states in conducting a four-hour distance education program on soybean aphid management in 2007.  Audio was carried over standard telephone lines and the video for Iowa was carried over the Connect system to 12 locations in Iowa.

Impact/Outcome:

It was disappointing that only seven attended in Crops Specialist Region 10.  However, all were dealers and together they represented approximately 140,000 acres.  All of the attendees rated the program as good or excellent.  On the average, attendees thought the information from the program had a value of approximately $16.50 per acre, suggesting a total value of approximately $2,310,000.
