There have been several reports in late-planted soybean, particularly in Leflore and Humphreys counties, of “flat pods” (See picture below). What has happened in these areas is an incidence of seed abortion or arrested development (Wiebold 2012, https://ipm.missouri.edu/cropPest/2012/11/Arrested-Development-in-the-Soybean-Field-Part2/index.cfm). Arrested development
For many years, one of the mainstay residual herbicides in soybean weed control systems was metribuzin (Sencor/Lexone). One of the drawbacks to metribuzin use is the sensitivity of some soybean varieties to this herbicide. A research project conducted by Mississippi State University and the University of Arkansas screened some of the modern germplasms available to producers for metribuzin tolerance.
