Soybeans were scouted at the V12 to R1 growth stage and when scouted, adult brown stink bugs were observed. However, these numbers did not reach threshold. These were soybeans planted in late April.
Conclusion
This issue was confirmed by an NC State Extension Specialist as damage from Brown Stink Bugs. Stink bugs have piercing mouth parts and feed on tender terminals, blooms, pods, and developing seeds within pods. In this environment, adults had reached threshold. Brown stink bugs can be controlled with acephate and pyrethroid insecticides. Continued scouting throughout the field and along the edges is recommended as well.
