Weed of the Week: Cutleaf Evening-primrose
Key identifying characteristics of cutleaf evening-primrose are the distinctive white mid-vein found on most leaves and a reddish base when cut with a sharp knife near the soil line.
Weed of the Week: Henbit
Henbit is native to Europe and Asia but can be found throughout the United States. It is common in crop fields, roadsides, pastures, and lawns throughout Mississippi.
Weed of the Week: Annual Bluegrass
Identifying features of annual bluegrass are its light green color, low and clumping growth habit, open leaf sheath, and lack of hairs.
Weed of the Week: Downy Brome
Downy brome can be problematic in some areas in winter wheat, pastures, and also in alfalfa.
Weed of the Week: Cheat
Cheat is a tufted, erect, winter annual grass species that is native to Europe. Cheat prefers open areas with full sunlight, such as cultivated fields, roadsides, and pastures.
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.
Weed of the Week: Southwestern Cupgrass
Southwestern cupgrass has become an increasing problem in recent years in Mississippi.
Weed of the Week: Broadleaf Signalgrass
Broadleaf signalgrass is widely dispersed throughout the southeastern region of the United States.
Weed of the Week: Browntop Millet
In Mississippi, browntop millet is found in cultivated areas, lawns, pastures, and along roadsides.
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.
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: 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.
Weed Control to Weed Management
When glyphosate was effective on most weeds, we were in a period of “weed controlâ€. However, over the last few years since glyphosate-resistant weeds have become so prevalent, we have entered a period of “weed managementâ€.
Cleaning Spray Tanks Is Critical
Sprayer cleanout after a herbicide application is a critical component to a successful herbicide application.
Timing Critical for Postemergence Herbicide Applications
A good rule of thumb is that the crop should be weed-free for the first four to six weeks following emergence to avoid yield loss.
MSU hires Jason Krutz as Irrigation Specialist for DREC
Mississippi State University has named Dr. Jason Krutz as Extension/Research Irrigation Specialist at the Delta Research and Extension Center
Herbicide Carryover
A problem that has become increasingly common in Mississippi and across the Midsouth over the last two years is corn injury from fomesafen (Flexstar, Flexstar GT, Prefix, Reflex) carryover.
Palmer Amaranth Control in Corn with HPPD Herbicides
Using herbicides with different modes of action is an excellent resistance management tool for glyphosate-resistant Palmer amaranth.
