Buttercup (Ranunculus species): One of the many yellow flowering weeds that we fight in pastures and hay meadows. Buttercup is a winter annual that thrives in weak or thin pastures. There are several species of this winter annual. They differ mainly in leaf shape and growth, but all produce characteristic bright yellow blossoms. March to early April is the best time to kill buttercup. The goal is to spray buttercup before bloom.   Fertilizing and liming to soil test recommendations and efficient utilization of pastures or hay fields are… Read More →

Grassbur is a grass weed that is very troublesome in pastures and hay meadows throughout Texas. Most grassburs are easily recognized in the mature stage of growth when the “bur” seed heads become apparent. The bur itself is actually a “capsule” that usually contains from 1 to 3 seeds. We tend to think of the grassbur species as a warm season annual plant. However, many grassburs are classified as perennials because they can survive from one year to the next. The presence of grassburs can be an indication… Read More →

As forage producers, we focus most of our energy on our warm season perennial pastures and hay meadows (bermudagrass, bahiagrass, etc.). That means most of our weed control efforts are also focused on warm season weeds (such as carolina horsenettle, blackberry, etc). Unfortunately, cool season weeds can be just as detrimental to our warm season perennial forages.   Annual ryegrass…a cool season annual forage often utilized by livestock producers for winter grazing. However, it’s often deemed an enemy of many a hay producer in East Texas. Later maturity… Read More →

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 how efficiently we use fertilizer.  The soil test is the first step in efficient fertilizer use and improved forage production.  Samples should be collected annually for hay meadows and every 2 to 3 years for grazing pastures.  For soil forms and bags contact your… Read More →

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 →

Buttercup (Ranunculus spp) Spray buttercup in late February or early March before it flowers. This weed is easily controlled with 2,4-D amine, Metsulfuron 60 DF, Cimarron Plus, Grazon P+D, GrazonNext HL and dicamba + 2,4-D (Weedmaster). In dormant bermudagrass/bahiagrass glyphosate (Roundup) will control buttercup at normal use rates.   Groundsel (Senecio spp) Metsulfuron 60DF or Cimarron Plus has proved to be the most effective herbicide for groundsel control. Apply in the rosette stage (~March). Grazon P+D provides partial control.   Red Sorrel (Rumex acetosella)   Grazon P+D provides… Read More →

If left uncontrolled, thick thistle stands can reduce grazing and result in less forage production. A single thistle plant can produce at least 4,000 seeds, which increases the chance for higher thistle populations in the pasture the following year. Consequently, management practices need to be conducted prior to flower formation for effective thistle control. Even if thistles have not infested your pasture in the past, it is ideal that your pastures are scouted in late fall through mid-spring (November to March) to ensure that thistles do not get… Read More →
