Heliothine Trap Counts, July 26, 2019
Both bollworm and tobacco budworm trap catches are average to above average this week. Bollworm moths are beginning to emerge from early corn fields, so strong moth flights are expected to continue for awhile since corn was planted over a
Cotton Leafroll Dwarf Virus: First Report in MS in 2019, Identification and Management Considerations
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.
Corn Disease Update: July 22, 2019
Since June, and most recently over the past few weeks, the corn disease questions have continued to include diseases from the lower canopy, in addition to Curvularia leaf spot. Southern rust was first detected in the MS corn crop on July 5. Since that time a limited number of counties have also observed the disease. However, at present, the amount of southern rust observed has been rather low.
Heliothine Trap Catches, July 12, 2019
Bollworm pheromone trap catches went down slightly in most counties, but rose sharply in Sunflower county, mostly due to a single trap which caught more than 400 moths during the week. Tobacco budworm catches were up in Noxubee and Washington

MS Ag Industry Council – 2019 Row Crop Update
We welcome you to attend the Row Crop Update at the 2019 Mississippi Agricultural Industry Council Annual Convention. This event is hosted at Perdido Beach Resort in Orange Beach, Alabama on Wednesday, July 24 starting at 8:00am.
How to Safely Terminate Irrigation in Corn
As the corn crop nears maturity, knowing when you can safely terminate irrigation, without sacrificing yield, or wasting money and labor through unnecessary irrigation is likely the most important decision that will affect your bottom line. In order to make this call, you need to estimate when the crop will reach maturity and how much moisture is present in your soil. This article outlines the steps needed to help make this process accurate and reliable.
Bollworm Management in Cotton: 2019 Guidelines
As we write this article, July 10, 2019, there are only sporadic reports of bollworm eggs beginning to show up in MS cotton. Generally the first big bollworm flight begins around the week of July 4 and peaks around July
Heliothine Trap Counts, July 5, 2019
Bollworm moth trap counts rose in all counties except Noxubee, which was extremely high last week. Most corn is no longer attractive to bollworm moths, so these moths are likely to lay most of their eggs in cotton and soybean.
Southwestern Corn Borer Traps – July 5, 2019
Several traps exceeded thresholds for the week ending on July 5. As a reminder, our current thresholds are 50 southwestern corn borer moths within a weeks time for corn that has not yet tasseled. From tassel to dent, the threshold

Southwestern Corn Borer Trap Counts – June 28, 2019
Southwestern corn borer trap numbers are starting to increase in some areas of the state. Scouting should be intensified over the next couple of weeks. It is likely some fields will reach threshold numbers over the next 10 days to
Heliothine Trap Counts, June 28, 2019
Bollworm and tobacco budworm moth catches in pheromone traps were very high in Noxubee County, but low to average in all other regions. I have been finding an unusually large number of yellow-striped armyworms in my pheromone traps the last
Moisture Sensors not Responding to Irrigation
The importance of soil moisture sensors is becoming more evident as we continue forward this growing season. This week we received a call regarding sensor readings that were assessed early this morning. The following are the data discussed in this
Sealing Soils Complicates Irrigation
Surface sealing in the Mississippi Delta typically occurs in soils that have a low clay and organic matter content but have a high silt fraction, i.e., most of our silt loam soils. Surface sealing, from an irrigation management standpoint, is
Heliothine Trap Catches, June 21, 2019
This week’s pheromone trap catches of adult bollworm moths were similar to last week, which are similar to historic levels in NE Mississippi, but much lower than typical in the MS Delta region. Tobacco budworm catches remained low except for 2

The Principles of Plant Pathology: The Response of the Host
Plant pathogens require a specific set of factors to occur within a given period of time for disease to occur. Oftentimes the disease triangle is the main image behind plant pathology, when a susceptible host, plant pathogenic organism and the environment work together to cause a plant disease. Even though the environment is most often considered the main factor behind the occurrence of plant diseases, the host and the response of the host can also be factored into the occurrence of plant diseases. Defining the different responses of the host (e.g., susceptible versus resistant) is important to understand the level of disease that can occur on a given host.
2018 Soybean OVT Foliar Disease Evaluations: Maturity Group V
The MSU OVT soybean locations were evaluated for disease during the 2018 season. Multiple diseases were evaluated at multiple locations and are provided in this post. Cercospora blight, Septoria brown spot, southern blight, and target spot were the most commonly encountered diseases during the season.
Corn Disease Update: June 14, 2019
Most of the corn disease questions over the past week to 10 days have had to do with diseases in the lower canopy. Common rust has been one of the most commonly observed diseases and continues to be observed once plants reach reproductive growth stages.
