September 2012 Supply and Demand Report Recap
I quickly want to introduce Dr. Brian Williams. Brian recently joined the Mississippi State Extension Service as a commodity marketing specialist. He will be taking over the corn, soybean and wheat duties and contributed to this post. Brian can be
Weed of the Week: Italian Ryegrass
Italian ryegrass plants germinate from fall through early spring, are highly competitive, and grow rapidly in the winter and early spring months.
Weed of the Week: Texas Millet
Texas millet is native to the southern United States and can be found in crop fields, pastures, roadsides, and untended areas in Mississippi.
The Principles of Plant Pathology: The Disease Triangle and Influence of the Environment
Plant pathogens require a specific set of factors to occur at the same time for disease to begin. More often than not diseases require a prolonged conducive environment before the pathogen can produce observable symptoms.
Weed of the Week: Southwestern Cupgrass
Southwestern cupgrass has become an increasing problem in recent years in Mississippi.
Weed of the Week: Browntop Millet

August USDA Report Recaps
[note: I have a prior obligation today. Here is a quick synopsis of the reports with more to come in later today or over the weekend] This morning USDA’s World Agricultural Outlook Board released their August estimates of U.S. and
Post-Harvest Weed Control Options
Tillage (disking, chisel plowing, etc.) is a common means of post-harvest weed control and a way to encourage rapid degradation of crop residues. However, this process can also bring new weed seeds to the surface, allowing them to germinate.
Weed of the Week: Sicklepod
Sicklepod is competitive with row crops during their seedling stages, so the first few weeks after planting are critical for control.
Fall Armyworms in Mississippi Crops
Fall armyworm can be a challenging pest to find and an even more challenging pest to manage in some crops. The damage that they cause and their management varies greatly from crop to crop. The reason for this is due to their preferred feeding sites on different crops and the presence of host strains.
Glyphosate-resistant Palmer Amaranth on Turnrows and Ditchbanks
One area of concern in glyphosate-resistant (GR) Palmer amaranth management is controlling this species on turnrows, field borders, and ditchbanks. Clean crop fields surrounded on turnrows and/or ditchbanks by GR Palmer amaranth is a common sight in areas where it
Weed of the Week: Partridgepea
Partridgepea is often used as a wildlife forage because of the variety of species that feed off of the plant.
Yield Reduction from late-season Corn Defoliation?
There is some late-planted Mississippi corn which has not reached physiological maturity. This corn may have its yield reduced somewhat by severe problems or stress. Included is a chart which may help assess potential corn yield reduction or risk.
When is the Best Time to Start Corn Harvest?
Corn harvest will be upon us much sooner than normal and expectations are generally much higher than recent years. However, we still need to get this corn crop out of the field and safely deliver it to market. Methods to successfully harvest your corn crop may vary depending on several factors.
Southern Corn Rust: Is a Late Fungicide Application Warranted?
Southern rust continues to be a topic of conversation throughout the MS corn production area. Presently, the disease can be observed at low levels in a patchy distribution throughout the Delta. However, there are likely some fields that contain hot spots of the disease. Scouting continues to be necessary in situations where a fungicide application could be beneficial. But, the necessity to apply a fungicide will be dependent on several important variables.
Weed of the Week: Hemp Sesbania
Late-emerging hemp sesbania is problematic at harvest due to its height, woody stem, and the fact that its black seed contaminate grain samples.
How Soon Did It Rain After You Sprayed?
Over the past week we have been getting a significant amount of rain across most of Mississippi. Unfortunately, most insects don’t mind the rain. Other than spider mites and aphids, we will likely have to continue managing insects in all crops despite the rain.
July Supply and Demand Report Shocker
The World Agricultural Outlook Board of USDA released their monthly World Agricultural Supply and Demand Estimates report (WASDE) this morning, July 11. The report revealed what most had feared, a much lower per acre yield than trend would suggest. The
R.R. Foil Plant Science Research (North Farm) Center Field Day – July 19, 2012
It has been a number of years since a field day was conducted at the R.R. Foil Plant Science Research center near the campus of Mississippi State University. To that end, a row crop field day will be held on
Ditch Bank Survey 6/27/2012
Overall, tarnished plant bug numbers appear to be decreasing across the Delta. Several things are contributing to this decline. The biggest factor is that the hot, dry weather is starting to take it’s toll on a lot of the wild
2012 USDA Acreage Report
(Correction to Mississippi cotton acreage change from March has been made) The much anticipated, and likely to be much debated, 2012 Acreage report from USDA was released this morning (June 29). Nationally, the report bumped up the number of acres
Corn Disease Update for June 22, 2012: Southern Rust Detected in Localized Areas
Numerous diseases and disease-like issues are being detected throughout the corn crop in this stage of the season. Nutrient burn, sun scald, northern corn leaf blight, gray leaf spot, and southern corn leaf rust can all be observed throughout localized areas of the Delta at this stage in the season.
Late Season Corn Irrigation and Termination
This season’s corn crop, particularly that planted in early March, is extraordinarily early. However, it will still need additional irrigation or rainfall to finish the crop out. This article discusses crop progress and methods to schedule and terminate irrigation water for corn.
