The cultivars contained in the Mississippi State University Official Variety Trial (OVT), as well as a few additional cultivars, were field-evaluated for their susceptibility/resistance to stem canker. Trials were conducted in Stoneville with toothpick-inoculated plants during the 2018 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.
The program for the 2018 Mississippi State University Row Crop Short Course has been finalized and over 650 people have already pre-registered for the event. The 2018 Row Crop Short Course will be held at the Cotton Mill Conference Center
Seed quality issues remain an important topic. Over the two weeks, portions of the MSU OVT that remained in the field post-harvest were harvested to consider quality differences between varieties. Purple seed stain as well as total damage, as a result of purple seed stain, Phomopsis seed decay and other issues that result in discoloration of soybean grain, were evaluated for the MG IV early and late and MG V early and late entries (n=133) in the Stoneville, MS loam OVT location.
The program for the 2018 Mississippi State University Row Crop Short Course has been finalized and over 350 people have already pre-registered for the event. The 2018 Row Crop Short Course will be held at the Cotton Mill Conference Center
Bacterial blight of cotton continues to be a disease of importance in the Mid-southern U.S. A project, sponsored by Cotton Incorporated, was recently completed and resulted in the development of a rapid, molecular diagnostic tool to detect the bacterium from infected cotton material. Even though the Mississippi Crop Situation blog is not the best venue for this type of post, the information contained in the post can reside here as a semi-permanent location for all interested parties to obtain the molecular diagnostic protocol since this project was sponsored by check-off funds.
Southern blight of soybean has been a much more widespread occurrence during the later stages of the 2018 season. Diagnosing plant diseases once plants have lost their leaves or do not exhibit all of the symptoms or signs of the fungus can be difficult. The current blog post contains information to differentiate between southern blight and some of the other more common diseases that produce interveinal chlorosis in the field.
Numerous questions over the past two weeks regarding the presence of foliar leaf spots in cotton. For the most part, limited reports of bacterial blight and target spot have been made. However, the specific location of lesions within the cotton canopy can oftentimes aid in the proper disease diagnosis.
A relatively quiet soybean disease year. However, over the past two weeks an increased number of diseases have been observed. Septoria brown spot and target spot continue to be the most commonly observed diseases.
We welcome you to attend the Row Crop Update at the 2018 Mississippi Agricultural Industry Council Annual Convention. This event is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 25.
The 2018 MSU-DREC Rice Producer Field Day will be held on August 2, at the Delta Research and Extension Center at 3:30 p.m. The program will begin at the Capps center with a brief welcome prior to departing for the field
Corn reproductive stages generally comprise nearly 60 days for corn hybrids grown in Mississippi at normal planting dates. Identification of these stages is critical for making prudent management decisions and anticipating crop response to practices and environmental conditions.
Over the past week the corn disease situation in MS has changed. Several foliar diseases are starting to be observed in our production system. However, the vast majority of the leaf spots present are not yield-limiting issues.
Numerous questions over the past several weeks regarding automatic foliar fungicides applications in soybean have been made. The current blog post should help guide decision-making regarding the R3/R4 automatic fungicide timing.
As the Mississippi corn crop approaches tassel stage, weather has fluctuated from dry to rainy conditions during recent weeks. Thus, how may this affect how the corn will respond to mid-season application of various management inputs, including nitrogen fertilizer or other products? This article will discuss factors that could dramatically affect corn response.
Soybean root diseases have started to be observed in the Delta. Over the past week several calls have been received regarding the presence of southern blight. Dead seedlings along with white mycelial growth below the soil line is a common observation in fields where southern blight occurs.
Mississippi State University will be hosting 2 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, and herbicide symptomology.
The MSU MG V OVT soybean locations were evaluated for disease during the 2017 season. Multiple diseases were rated at multiple locations and are provided in this post by herbicide trait. Cercospora blight, Septoria brown spot and target spot were the three most commonly encountered diseases during the season.

Observations of target spot were made in the MSU OVT location conducted in Lucedale, MS during 2017. Included in this blog post are the observations of disease on leaves as well as the percent defoliation from all 52 varieties included.
The Mississippi State University Extension Service will be hosting a number of county row crop extension meetings in the spring of 2018. Each meeting will cover issues specific to the area and will provide information on weeds, insects, disease, economics,
A Maturity Group IV and V variety trial was conducted in Verona, MS at the NMREC during the 2017 season. Yield and disease data are included in the attached report for all entries contained in the trial (RoundUp, Conventional and LibertyLink).

Over the past several weeks numerous comments have been made regarding the validity of the harvested yield data from the Clarksdale OVT location. Several varieties were observed to be “poor performers” based on low yield. The Clarksdale OVT was observed to contain severe stem canker in multiple variety entries. The current blog post contains comparisons between the visual observations of stem canker (0-9 scale) and harvested yield from the 2017 MSU OVT entries at the Clarksdale location.
