2020 Soybean Stem Canker Inoculated Variety Trial Evaluations
The cultivars contained in the Mississippi State University Official Variety Trial (OVT), as well as several additional cultivars, were field-evaluated for their susceptibility/resistance to stem canker. Trials were conducted in Stoneville with toothpick-inoculated plants during the 2020 season. Tables contain the average of the field observations (on a 0-9 scale) as well as an assessment of resistance to stem canker (R, MR, MS, S) based on the evaluations conducted.
2020 MSU Corn Hybrid Trial Disease Evaluations – Non-Irrigated Locations
Non-irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2020 season. Curvularia leaf spot and southern corn leaf blight were the two most commonly observed diseases. Little if any northern corn leaf blight (NCLB) was observed; however, where observed the evaluations were captured and are contained in the associated tables from each location. In addition, and when present, lodging was evaluated on a percent scale to capture any meaningful differences between hybrids. Presently, the evaluations from the non-irrigated locations (n=6) are included in the current post.

Mississippi Soybean Rust Foliar Disease Update: September 5, 2020
Soybean rust has been observed to be much more widespread throughout the MS soybean production area this year. Normally, soybean rust is a late-season disease that goes unnoticed and ends up being observed at growth stages when the disease does not likely reduce yield (R6.5+). Soybean rust has been observed for the last three weeks across MS in soybean fields that range from R5.5 to R7. In some specific parts of the state management options have already been suggested due to the rust pressure in adjacent fields.
Identifying Late Season Soybean Growth Stages
As we move closer to maturity, there are many decisions to be made on termination timing of various management practices. At this time of the season, we can use late season soybean growth stages as a guide to decide when
