Weed of the Week: Dallisgrass

Dallisgrass is a warm-season perennial that has grazing potential. Dallisgrass is palatable and has a higher level of nutritive value than bahiagrass and some bermudagrass varieties, and it can retain its nutritive value later into the summer. Dallisgrass, however, produces a lower dry matter yield than some bermudagrass varieties. One concern with dallisgrass is the potential for an “ergot” fungus (Claviceps spp.) to infect seedheads and cause dallisgrass poisoning (also known as dallisgrass staggers). The fungus infects the seedheads typically in late summer or fall. The affected animals… Read More →

Spring is Here?

With the First Day of Spring coming up and the most recent warm weather and sunny days we start thinking about our warm season pastures and hay meadows. A few things to keep in mind as our warm season forages begin to break dormancy… Soil Test!  Soil Test!  Soil Test!  If you have not done so for this year, please consider obtaining a soil test now.  There is not much that can be done regarding the high cost of fertilizer, but there is much we can do regarding… Read More →

Timing on Weed Control is Critical

Our human nature is to find a simple, one time solution for our problems. Unfortunately, this simple, one time solution does not exist for weed control in pastures and hay meadows. There are several factors that are important when it comes to weed control. These include:   Weed Identification: We cannot make the best management decisions if we don’t even know what the plant is we are trying to eradicate. Identification will determine the timing of our herbicide application along with the herbicide we choose. There are a… Read More →

Suns Out, Fertilizer Out?

After a cold, dreary winter we get anxious about our warm season perennial pastures and hay meadows. We start panicking about the winter weeds we see growing, the volunteer ryegrass we see growing and we start making calls to our local fertilizer retailer. Find more information about dealing with volunteer ryegrass here and dealing with winter weeds here. Now, let’s take a moment and talk about the RIGHT time to fertilize our warm season pastures/hay meadows.   First and foremost, soil test. If you have not done so… Read More →

Weed of the Week: Mayweed chamomile

Mayweed chamomile, often called dog fennel, stinking chamomile, or stinking mayweed is an annual bushy broadleaf plant that germinates in early spring. Mayweed chamomile inhabits crop fields, roadsides, pastures, hay meadows and other disturbed, unmanaged sites. Leaves are alternate to one another along the stem, are lobed to deeply divided, and nearly hairless to hairy. Mayweed chamomile can have a spreading form or be an erect plant, reaching 6 inches to 3 feet long. A distinguishing characteristic of mayweed is it’s unpleasant odor. Flowering takes place from spring… Read More →

What is Coastal, Tifton 85 and Jiggs?

Most people think these forages are a species of their own. But they are not. They are hybrid varieties of Bermudagrass (Cynodon dactylon). Bermudagrass is a warm-season perennial grass that spreads mainly by rhizomes (underground stems) and stolons (horizontal aboveground stems).  The grass tolerates a wide range of soil types and soil pH values, thus making it adapted to most of the southern US.  ‘Coastal’: A hybrid between ‘Tift’ bermudagrass, a vigorous growing bermudagrass found in an old field near Tifton, Georgia, and an introduction from South Africa. … Read More →

Renovation

During the dormant season we often get anxious for warm weather and green pastures so we start thinking about renovation. Renovation is a practice or series of management practices which “restores the vigor” or “makes new again.” In pasture management, renovation refers to improvement of a permanent pasture by changed management. Renovation of bermudagrass pastures may be as simple as soil testing and applying proper fertilization; or, it may be as complex and intensive as destroying the existing sod, preparing a seedbed and sprigging again.   Some renovation… Read More →

Weed of the Week: Texas groundsel

Texas groundsel or Texas squaw-weed (Senecio ampullaceus) is a cool-season annual broadleaf plant that grows to 12 to 30 inches tall. The plants are often whitish with hair, but can be nearly hairless.  The unlobed, clasping leaves gradually reduce in size toward the top of the plant. Showy yellow flowers are produced in the spring.  Texas groundsel is found in the eastern half of the state and is abundant on sandy soils and may be a predominant species in freshly cleared forest. Members of the genus Senecio can… Read More →
