Come and join us from 9:30 a.m. - 3 p.m. on Monday, March 2nd, at the Eastern Nebraska Research and Extension Center (1071 County Road G, Ithaca, NE) for the latest information on this newly emerging soybean pest.
Soybean gall midge infestations have been confirmed in six new Nebraska counties since 2018.Treatment is not recommended at this time, but scouting and reporting infestations will continue to be important to plan for management next year.
Populations of immature grasshoppers are being reported in areas bordering crop fields in several parts of Nebraska. If these grasshopper species are one of the four major species that are likely to infest cropland, control may be warranted if high numbers are present.
A significant number of soybean gall midge adults have been collected from this year’s soybean fields in east-central and northeast Nebraska. Dead and dying plants have been observed near infested sites in both northeast and east central Nebraska.
Volunteer wheat can create a "green bridge," providing a route for mites to move to and infest emerging wheat. These mites can then transmit wheat streak mosaic virus, High Plains virus, and Triticum mosaic virus, or all of them to create a complex of infections.
Treatment is not recommended for the painted lady butterfly currently being seen in high numbers and could endanger beneficial insects. Treatment thresholds offer guidance for treating feeding caterpillars.
