The 2019 planting season has gotten off to a rough start with all of the rain. Today (Thursday May 9), we have gotten well over 4 inches of rain in the last 24 hours in Stoneville and a lot of
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.
Brown stink bugs have been treated on a fair number of acres of corn in the Delta this year. With the loss of Methyl, there are not a lot of good choices to control this pest in corn. We are
The Mississippi State University Extension Service is offering free Soybean Cyst Nematode testing through August 30, 2019. For details click the links below. Soybean Cyst Nematode Sample Submission Form SCOUTING AND SOIL TESTING FOR SOYBEAN CYST NEMATODE
Every few years we have a surge of potato leafhopper calls in soybean in MS. This is one of those years. Potato leafhoppers strongly prefer smooth leaf soybean varieties and I suspect that the calls increase on years where popular
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.
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. We have some of the earliest beans that are R3/R4 getting fungicide applications
This is a video showing the methods used to determine the vegetative growth stages of corn or sorghum in the field. Further information can be found in the accompanying Mississippi Crop Situation blog article.
Vegetative growth stages of corn or sorghum are determined by counting the number of fully emerged leaves with leaf collars present. This methodology can be used to anticipate growth and determine appropriate timing of many management decisions, including herbicide application, sidedress fertilizer, etc….

In 2017, we were able to accurately predict the threat of RBSB based on sampling ditch banks in the spring. Every year we sample ditch banks across the state to make collections of various insect pests. With most pests, such
I have recently received a few call about slugs in corn. I suspect this will increase in more crops as planting continues and they begin to emerge. Slug problems usually start on corn first, then move to soybeans, then cotton in our area.
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.
The disease situation in MS soybean fields has certainly increased over the past 7-14 days. Active aerial web blight, Cercospora blight, soybean rust, and target spot remain the most commonly observed diseases over much of the production area.
The ArkLaMiss Redbanded Stink Bug Forum was a huge success. There were numerous attendees present and many more who live streamed. Click the following ling to watch the recorded version. ArkLaMiss RBSB Forum

Yesterday, light soybean rust infection was observed in Noxubee County, MS in soybean plants beyond the R5.5 growth stage. The specific information in this blog post should serve as an update to the soybean rust disease situation as well as including some general guidelines with regards to potential disease management scenarios.
We saw a surge in RBSB numbers a few weeks ago into March planted soybeans that were approaching R6 growth stage but since then populations have moderated. Just in the last few days we are now seeing another big surge moving into
Increased reports of disease in the corn crop in MS have been made over the past week. Normally, as corn matures, the incidence and severity of corn diseases observed with increase. Presently, common rust, Diplodia leaf streak, northern corn leaf blight, and southern rust can all be observed in our corn production system; however, southern rust has only been observed on an extremely limited number of acres to this point in the season.
Diagnosing common and southern rust in the field can oftentimes be difficult. Subtle differences between the two diseases can occur at different parts of the growing season as well as sections of the crop canopy.
Mississippi State University will be hosting 4 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. There
Limited wheat acres in MS have meant for a fairly quiet winter. However, the observation of wheat diseases has increased over the past several weeks with the major questions coming from either vernalization issues (lack of chilling hours) or leaf rust.
