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 →

Weed of the Week: Bahiagrass (Paspalum notatum) Bahiagrass is a warm season perennial that grows in Texas. Bahiagrass spreads by J-shaped purplish rhizomes and seed. The seed head consists of two or three spikes. Bahiagrass can be very aggressive and take over quickly especially in areas where competition is weak. Bahiagrass is very tolerant of low fertility and soil acidity.   Bahiagrass can be utilized for grazing. Some of it’s attractions for producers include its excellent adaptation, ease of management, persistence under low fertilization and close grazing. Bahiagrass… Read More →

Weed of the Week: Johnsongrass (Sorghum halepense): Johnsongrass is a warm season perennial grass that is one of the most common and troublesome weeds in agriculture. It is commonly found on roadsides, pastures and hay fields. It grows erect from 3 to 6 feet. Johnsongrass spreads by seeds and rhizomes (underground stems). The seedhead is a large, open panicle often with a purplish tint. Johnsongrass leaves have a large white midrib and a smooth, glossy appearance. Stems are smooth with no hairs.   Select Herbicide Options: Outrider (for… Read More →

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 →

Believe it or not, we can actually grow some forages other than Bermudagrass and Bahiagrass in Texas! Warm season perennial grasses, such as bermudagrass and bahiagrass, make great foundations for pastures in Texas. However, there are additional forages that can be utilized for pasture or hay production in Texas. As always, when selecting forage species make sure to match species and variety to your location (soil type and average rainfall) as well as to your production system goals. For assistance in selecting a forage species and/or variety contact… Read More →

Weed of the Week: Silverleaf Nightshade (Solanum elaeagnifolium) Silverleaf nightshade has foliage with gray or silvery appearance, violet, light blue or white flowers, and is 1 to 3 feet tall. Stems are sparsely covered with short yellow thorns. Leaves and stems have a dense silvery covering of hair. Optimum time to spray with a herbicide is during bloom.   Select Herbicide Options: Weedmaster Duracor GrazonNext HL Grazon P+D Pasturall HL Surmount Chaparral (for bermudagrass pastures, will destroy bahiagrass) Cimarron Max (for bermudagrass pastures, will destroy bahiagrass) Pastora (for… Read More →

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 →

Crabgrass is a warm-season annual grass that is commonly found in pastures and hay meadows in parts of Texas. Relative to other warm-season annual grasses, crabgrass has a low- to medium-yield potential but is high in forage quality. As such, it is often a desirable component in pastures and is sometimes planted for forage in pastures. As is the case with many annual grass species, crabgrass is a prolific seed producer which enables new stands to establish in subsequent growing seasons for summer grazing. Due to its high-volume… Read More →

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 →

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 →
