With soybean gall midge emergence dates and locations advancing in the state, Nebraska Extension educators stress the importance of scouting and documenting observations, which can inform ongoing research on management options.
With soybean aphid infestations, it's important to preserve natural enemies under an integrated pest management approach, as well as treating only when pest populations reach economic or treatment thresholds, to let beneficial insects do their work.
Soybean aphids in Nebraska typically reach the economic threshold and require treatment in late July through August. Treatment during this time is usually enough to keep aphid populations from resurging before they leave fields for the season.
Hosted at four sites across central and eastern Nebraska, the field days will provide research-based information to enhance soybean profitability, addressing both local and global issues significant to farmers.
Robert Koch of the University of Minnesota speaks to the FarmBits team about the soybean pest management research being conducted in his lab, using remote sensing for scouting and sampling fields for soybean aphids.
The new webinar series will offer the latest information and data on soybean gall midge distribution in the Midwest, scouting tips, insecticide applications and potential strategies that may assist growers in developing long-term pest management.
Soybean gall midge (SGM) injury and pressure varied considerably across its geographic range, with the largest concentration of injured soybean fields occurring in east-central Nebraska this season. To date, a total of 140 Midwestern counties have been identified as infested with SGM.
