Winter Weeds: Do they matter?

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 →

Weed of the Week: Thistles

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 →

Planting Winter Forages

AgriLife Today Article Late September-early October is the ideal time for planting cool season annual forages such as annual ryegrass, small grains (rye, wheat or oats) and/or cool season annual legumes. Anytime we are incorporating new forages into our production systems it is important to make sure to match the forage species to your location (soil type, average annual rainfall, intended use, etc). If you have questions about forages appropriate for your area contact your local county extension agent. Three methods for establishing cool-season annual grasses include planting… Read More →

Potassium is for Persistence

We rely heavily on our bermudagrass pastures and hay meadows during the summer in some parts of Texas. Often times we are disappointed with production, see a thinning of our stand and/or see disease like symptoms. This is often times referred to as “Bermudagrass Decline.” We quickly blame weather. Granted weather can have an impact on each of those issues. However, there is often a deeper problem that we need to access. Primary Causes: Low Potassium (K) Fertility: A deficiency in K will result in poor stress tolerance,… Read More →

Bermudagrass Stem Maggot

June 28, 2017 I am starting to see signs of the bermudagrass stem maggots in parts of Texas. I recommend scouting your fields, especially your hay meadows, as we continue into summer.
