Due to restrictions limiting public gatherings related to the pandemic, the MSU Row Crop Team are releasing virtual educational programs to help prepare for the upcoming growing season. These corn episodes include two programs discussing planting practices and stand establishment, as well as soil, water and nutrient management.
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.
The presence of foliar diseases in the MS corn production system has certainly increased over the past several weeks. In general, the presence of disease increases as the corn crop ages. Questions regarding common and southern rust, Curvularia leaf spot, Diplodia leaf streak, and Physoderma brown spot have been posed over the past several weeks. Information regarding the aforementioned diseases is contained in the current blog post.
The MSU OVT soybean locations were evaluated for disease during the 2019 season. 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.

The Plant Diagnostic Lab is offering free nematode testing for Mississippi soybean fields through August 30, 2020. The free testing, offered as a portion of a check-off funded project by the United Soybean Board, has been expanded to include all plant parasitic nematodes of soybean, not just soybean cyst nematode (SCN).
Even though we are late in the season, some of the disease situations observed across MS continue to change.
A lot of information regarding a new cotton virus, cotton leafroll dwarf virus (CLRDV), has been swirling around the internet since last fall. A low number of CLRDV-positive samples were detected from Coahoma County, MS last week. The current blog post contains information regarding the virus.
