Brief Project Summary:

Little to no information is available on soybean gall midge or its interactions with soybean pathogens. No information is available on the economic losses with either or both being present on the same plant. The rapid and widespread infestation of this pest in soybeans throughout four key soybean-producing states (Nebraska, Iowa, South Dakota and Minnesota) has raised major concerns about what management practices are needed to mitigate losses. Field observations and communications with growers, consultants, and ag professionals have shown there are a number of questions surrounding the interactions between soybean gall midge and plant disease both in terms of infestation potential and yield...

Project Deliverables

This 3-yr project would increase efforts to assess the timing of emergence of soybean gall midge adults and expand this effort to evaluate the potential infestation period over the growing season. Furthermore, interactions between soybean gall midge and plant diseases will also be determined. Sentinel plants would be exposed to a field for a period of one-week beginning in early spring through late August and evaluated for the presence of the midge and plant diseases.
Sites would be adjacent to areas with high pressure from soybean gall midge the previous season. In addition, sites would consist of field plots with insecticide, fungicide and combination treatments to evaluate the role and interactions between fungal pathogens and soybean gall midge. Updates on this study would be provided during the growing season via UNL CropWatch and Twitter. Findings will also be disseminated through field days, conferences, as well as extension and research publications. Results from this study would provide farmers with an understanding of the risk period for
infestation from soybean gall midge and its yield loss interactions with plant diseases.

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.
