Brief Project Summary:

In late June 2018, entomologists in Nebraska, Iowa, South Dakota, and Minnesota began receiving reports of soybean fields with visible signs of dead or dying plants that were found to be associated with soybean gall midge. By the fall of 2019, an additional 30 counties were identified as infested in those states, and an infestation was reported in northwest Missouri. To document clientele need for research on this new pest, a research petition was developed to determine the threat of soybean gall midge and the need for research on this new species. In Nebraska, a total of 367 signatures have been obtained since the petition was developed on December 18th, 2018 to Feb 20th, 2019. The presence...

Information And Results
Project Deliverables

Resulting data from this project will be presented at a number of Nebraska Extension efforts such as Soybean Management Field Days (approx. 400 attendees), Nebraska Crop Management Conference (approx. 300 attendees), Midwest Crop Production Clinic (50 attendees), Crop Production Clinics (1,400 attendees), and Nebraska Soybean Expo (300 attendees). Updates on research progress will be presented through Blackboard Connect Alert System, Twitter, Market Journal, grower listserves, Market Journal interviews, and UNL Cropwatch articles. We would expect that at least two peer reviewed publications will result from this work.

Data from the 2022 growing season was lost due to a hail storm on June 7th. Our previous years data indicated there may be planting dates that are highly susceptible to injury from soybean gall midge. Growers looking to potentially reduce soybean gall midge populations for future years may want to consider delayed planting if they have significant historical injury and pressure from soybean gall midge. Seed treatment impacts were limited to soybean plantings from April 22nd to May 12th. Our results indicate that planting date alone is more effective but more research is needed.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
