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.
Heliothine Trap Counts, May 22, 2024
Below are the trap catches in pheromone traps for corn earworm (bollworm) and tobacco budworm. The numbers reported are the average trap catch in the county for the week. There are 3-4 traps for each species placed in each reported
Video – How to Identify Corn Vegetative Growth Stages
This video shows how to identify vegetative growth stages of corn or sorghum in the field. In this case we inspect two different examples of corn that have progressed into rapid growth stages.
How to Determine Corn Vegetative Growth Stages
Vegetative growth stages of corn are determined by counting the number of fully emerged leaves with leaf collars present. It is important to appreciate this methodology since it is a basis for timing many management practices, including herbicide application, sidedress fertilizer, and others.
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.
Where to Install Soil Moisture Sensors for Pivot Irrigation
Small plot and on-farm research in Mississippi have shown that using soil moisture sensors to schedule irrigations can reduce water applied while maintaining or improving yield and profitability relative to other methods. However, placement and installation affect the accuracy of
Agronomic Scout Schools (June 2024)
The Mississippi State Row Crop Team will be hosting three scout schools in 2024. The program will cover insects, disease, fertility, and agronomy. These events are free of charge, and all are welcome. Each scout school will serve as an
Redbanded Stink Bug Survey of 2024
Over the last month, we have been conducting the redbanded stink bug ditch bank surveys. To date, we have not found any redbanded stink bugs in the following counties: Attala Choctaw Hinds Holmes Leake Madison Montgomery Oktibbeha Webster Winston Yazoo
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.
Improving Corn Response to Nitrogen Fertilizer
Corn response to nitrogen fertilizer is a dynamic situation that often becomes more challenging when rains abound. This article gives recommendations to improve corn response to nitrogen fertilizer and reduce risks in the Midsouth.
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.
