Mississippi Cotton Early Season Management Considerations
The MSU OVT soybean locations were evaluated for disease during the 2020 season. The MG V entires are contained in the current post. Multiple diseases were evaluated at multiple locations and are provided in this post. Cercospora blight, frogeye leaf spot (when present), Septoria brown spot, southern blight, and target spot were the most commonly encountered diseases during the season. In addition, green stem was also evaluated at multiple locations.

2020 Mississippi Cotton Official Small Plot Variety Trials
Response of the cotton varieties contained within the 2020 Official Variety Trial to bacterial blight following evaluations conducted on inoculated plots from Stoneville, MS are included in this blog post.
When previously posted, two locations from this year’s program had yet to be harvested. Since that time, harvest has been completed and the link below has been updated to reflect the addition of these data. As a reminder, the annual
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.
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.

The annual MSU Extension Soybean Variety Demonstration Program is conducted using a set of varieties with proven performance. These varieties are grown in a production setting on various soils and management systems around the state. The sets for 2020 represented
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.
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
