Grasshoppers!

There are about 150 species of grasshoppers in the state of Texas, but 90% of the damage to crops, gardens, trees, and pastures is caused by just 5 species. Grasshoppers deposit their eggs 1/2 to 2 inches below the soil surface in pod-like structures. Each egg pod consists of 20 to 120 eggs. Egg pods are very resistant to cold and can easily survive the winter if the soil is not disturbed. Grasshoppers deposit eggs in fallow fields, ditches, fencerows, and weedy areas, as well as in crop… Read More →

Fall Armyworms

When rain comes back to Central & East Texas, fall army worm infestations may develop (or already have) in pastures and hayfields. Larvae of fall armyworms are green, brown, or black with white to yellowish lines running from head to tail. A distinct white line between the eyes forms an inverted “Y” pattern on the face. Armyworms are very small at first, cause little plant damage and as a result often go unnoticed. Larvae feed for 2-3 weeks and full-grown larvae are about 1 to 1 ½ inches long…. Read More →

Herbicide Applications During Dry, Hot Months

Invasive brush can decrease forage productivity for livestock or decrease brush diversity valuable for wildlife habitat.  Most ranchers find themselves constantly considering options for brush management, weighing not only the cost and effectiveness, but also when they can find the time to complete the treatments.   As temperatures continue to climb across the state and the chances of rainfall seem to be weakening, it’s important to consider the effect this will have on any herbicide applications. Treating weeds or brush with a leaf spray application when temperatures are as… Read More →

Bermudagrass Stem Maggot

The bermudagrass stem maggot (Atherigona reversura), a pest of bermudagrass forage in Texas has been reported in multiple counties since 2012. The bermudagrass stem maggot is native to south Asia (from Japan westward to Pakistan) and was first reported in the United States in Georgia in 2010. This pest only infests bermudagrass and stargrass (Cynodon spp.). The fly (yellow with black head) lays its eggs within the stem of the bermudagrass plant. Once the egg hatches the larva, or maggot, (white with black head, 1/8” – 3/16” long)… 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 →

Weed of the Week: Carolina Horse Nettle

Carolina Horsenettle (Solanum carolinense) A warm season perennial, Carolina horse nettle can grow to 2 feet tall. It has dark green leaves that are sharply lobed with a pointed tip. Carolina horse nettle has large spines on the stems and leaves. Each of its mostly oval leaves has several teeth or shallow lobes on both sides. Horse nettle has clusters of white to purple flowers and they bloom May to October. Horse nettle also produces a fruit that is about 1/2 inch in diameter; it is green with… Read More →

Nitrogen Fertilizer Sources

Nitrogen is an essential plant nutrient. Plants readily take up and use two forms of soil nitrogen, ammonium (NH4+) and nitrate (NO3-). Other forms of nitrogen must be converted to one of these compounds before plants can utilize them directly for plant growth. Sources of Nitrogen: Plants such as legumes “make their own” nitrogen. A symbiotic (positive for both parties) relationship between a legume and rhizobium bacteria develops and the bacteria “fix” nitrogen out of the atmosphere and convert the nitrogen gas into forms that can be used… Read More →

Limestone: Who, What, When, Why & How

Who Needs Limestone: Many Texas soils are acid soils; that is, the soil pH is less than 7.0. Soil acidity is caused by various environmental, climatic, and cultural factors. The most common of these factors are: Parent material from which the soil is derived. Leaching by rainfall or irrigation that removes basic elements such as calcium, magnesium, and sodium from the soil profile leaving acidic hydrogen, aluminum, and manganese. Cultural practices such as nitrogen fertilization, removal of harvested crops and associated basic elements, and soil erosion, which results… Read More →

Sprayer Maintenance

Tuning up your sprayer can better prepare you for accurate and effective herbicide applications. Any sprayer, old or new will perform better if you check it over before heading into the field. The most common causes of inconsistent spray patterns are nozzle tips with different fan angles on the boom, uneven boom heights and clogged nozzles. Follow manufacturer recommendations to select nozzles for the best coverage. Make sure nozzles are clear of debris and residue. If a spray tip does clog, only use a soft bristled brush or… Read More →

Hay Meadow’s Friend or Foe?

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. Volunteer annual ryegrass can be common in hay meadows. Winter rainfalls can promote seed germination and seeds can survive for multiple years in our soils. Later maturity of annual ryegrass can delay or prevent our warm season perennial forages (i.e. bermudagrass or bahiagrass) from breaking dormancy in April/May therefore delaying our initial hay cutting.   So how do we manage… Read More →
