Crisis Exemption for Intrepid 2F for Fall Armyworm in Mississippi Rice
Over the last 7 to 10 days, fall armyworm infestations in rice have increased a good bit. Currently pyrethroids are the only products labeled for fall armyworm management in rice. Since 2021 the performance of pyrethroids against fall armyworm has
When to 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. This article outlines the steps needed to help make these decisions accurately and reliable.
Southwestern Corn Borer Monitoring – Week Ending 5/25/2024
With corn acres rapidly approaching tassel, southwestern corn borer traps are beginning to be deployed across the state. Limited data is available for this week but will become more abundant as the season progresses.
When should we initiate Irrigation to Enhance Corn Yield?
At the first hint of summer weather, there is often a rush to replenish moisture in corn fields with irrigation. However, inadequate soil moisture is not nearly as limiting as usually perceived. This article will discuss when to initiate irrigation based upon what is best for the corn crop.
Optimum Timing and Management for Tassel Applications on Corn
As the Mississippi corn crop approaches tassel, crop health and weather may greatly affect crop response to various management inputs, including nitrogen fertilizer or other products. This article will discuss factors that may affect your strategy and improve your response.
Grain Sorghum Planting and Early Management Recommendations
Grain sorghum has some unique characteristics differing from our major row crops. This article discusses key planting and management practices needed to successfully plant sorghum and get it off to a strong start this spring.
2024 Thrips Considerations
At-planting: Since the development of widespread resistance to neonicotinoid seed treatments, we have been recommending the use of Acephate (Orthene) at planting, either as an overtreatment at 6.4 oz per cwt or up to a pound in-furrow. For several years,
2024 Grain Sorghum Hybrid Suggestions
This article lists those sorghum hybrids which have demonstrated superior yields in the Mississippi Grain Sorghum Hybrid Trials. Thus, this is a great barometer to select the best adapted sorghum hybrids for your farm.
How to Assess Uneven Stands and Corn Replanting Methods
Assessing corn stands to make replant decisions should likely involve more than simply taking stand counts. This article discusses how emergence disparity affects corn yield potential, and methods to replant your crop, when needed.
2023 Verona, MS Soybean Variety Trial Frogeye Leaf Spot Evaluation Ratings
During 2023 multiple soybean OVT locations were observed for the presence of disease. The Verona, MS location was observed to have the most consistent frogeye leaf spot data across all of the varieties planted. Observations were made and those are reported in the corresponding data tables.
When is the Cut-Off Date for Planting Corn?
When rain or other issues restrict planting opportunities, you may be wondering how to proceed with crop planting intentions. This newsletter helps address that question by explaining how corn responds to late planting when grown in different production systems based upon research conducted at Mississippi State University.
2023 Soybean Stem Canker Inoculated Variety Trial Evaluations
The cultivars contained in the 2023 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. 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.
Managing Weeds in Mississippi without Dicamba
On February 6, 2024, U.S. District Court for the District of Arizona vacated the 2020 registrations of Xtendimax, Engenia, and Tavium herbicides (all products containing dicamba) for applications to Xtend and XtendFlex soybean and cotton varieties. This ruling applies to
Keys to Success for Early Corn Planting
Corn is very dependent on stand quality and uniformity to optimize productivity. Although things look promising for early planting this spring, there is typically considerably more risk associated with adverse weather for early plantings, compared to later in the spring. This article discusses how to assess corn planting suitability, strategies to improve your stand, and factors that affect what seeding rate you should plant.
Identifying Wheat Growth Stages using the Feekes Scale
The Feekes scale is likely the most commonly used system to describe wheat and other small grain’s growth and development stages. Understanding of wheat plant development is important so that you may better time management inputs to optimize crop response. This article helps you identify specific wheat growth stages.

Ag Safety Day at DREC
The Delta Research and Extension Center is hosting the upcoming Ag and Safety Day on Thursday February 8th, 2024 from 9:00am to 4:00pm. The day will be highlighted by Farm Bureau’s grain bin safety training featuring their grain bin safety
2023 MSU Corn Hybrid Trial Disease Evaluations – Non-irrigated Locations
Non-irrigated locations containing the MSU official corn hybrid trials (OHT) were evaluated for foliar diseases during the 2023 season. Curvularia leaf spot was the most prevalent foliar disease observed. A limited amount of southern rust was observed at two locations. Data are presented as the severity of each disease from each irrigated location on a 0-9 scale for each of the hybrids included in the irrigated location evaluations. Presently, the evaluations from the non-irrigated locations (n=5) are included in the current post.
