2015 Soybean OVT Foliar Disease Ratings: Maturity Group V
Field evaluations of the Maturity Group IV entries in the MSU OVT were conducted at each of the locations where trials were planted (Brooksville, Clarksdale (n=2), Falkner, Longwood, Raymond, and Stoneville (n=3)). Entries were observed for their reaction to the diseases
2015 Soybean OVT Foliar Disease Ratings: Maturity Group IV
The MSU OVT soybean locations were rated for disease during the 2015 season. Multiple diseases were rated at multiple locations. In the past, Cerospora leaf blight and frogeye leaf spot have been the two main diseases rated. In 2015, Septoria brown spot as well as target spot were included as well as a green stem rating. Phytotoxicity, following an accidental fungicide application, was rated in the Maturity Group IV early and late entries at one location.
2015 Soybean OVT Stem Canker Ratings
The cultivars contained in the Mississippi State University Official Variety Trial (OVT), as well as a few added cultivars, were field-evaluated for their susceptibility/resistance to stem canker. Trials were conducted in Stoneville with toothpick-inoculated plants during the 2015 season. Tables contain the average ratings (on a 0-9 scale) as well as an assessment of resistance to stem canker (R, MR, MS, S) based on the ratings conducted.
2015 MSU-ES Soybean Variety Demonstration Program Results
The On-Farm Soybean Variety Demonstration Program is conducted using a set of varieties with proven performance. These varieties are grown in a production setting on various soil types and management systems around the state. Demonstration sets for both maturity group
First Look: 2015 North MS Research and Extension Center Soybean Disease Ratings (EDITED)
The soybean variety trial ratings from the North Mississippi Research and Extension Center (NMREC) are included (MG III, IV, and V). The yield publication from NMREC will be posted at a later date. As in the past, plots were rated for Cercospora leaf blight (CLB) and frogeye leaf spot (FLS). However, this year, Septoria brown spot (Septoria) and target spot were also rated when the diseases were present. Green stem ratings were conducted for the Maturity Group IV early and late varieties.

Are Late-Season Soybean Rust Observations Important?
Late-season soybean rust observations occur on almost an annual basis. Even though the majority of the soybean crop has escaped yield loss as a result of soybean rust again for the 2015 season, determining the extent of the disease in MS as well as potential locations where the fungus could overwinter continue to be an important part of the monitoring/scouting program. At present (9/22), soybean rust has been detected in 41 counties.

Soybean Disease Update: September 5, 2015
Soybean diseases continue to be observed throughout the MS soybean production area. The number of counties (13, as of 9/4/2015) exhibiting soybean rust has increased over the past several days. However, low levels of infection have been observed at most locations. Frogeye leaf spot, Cercospora blight, target spot, and stem canker also continue to be observed.

Dectes Stem Borer: Biology, Damage, and Management in Soybeans
There have been numerous calls and questions about Dectes Stem Borer over the last few years. It seems that numbers are increasing each year. This is not surprising when you consider the biology of the insect coupled with an increase in soybean acres in MS.
Soybean Loopers and the Effect of Defoliation on Yield
We have been getting calls on loopers showing up in soybean for about 2 weeks. In recent days there have been reports of defoliation exceeding 20% or numbers exceeding threshold in some areas in the central to southern part of the state. The bulk of our soybean loopers typically show mid to late August or even into September so this is a little early but certainly not unusual. Soybean loopers are migratory and work their way north each year from southern latitudes. Early arrival could be due to a number of reasons.
