Engineered cotton uses weed-suppression chemical as nutrient

by Kay Ledbetter, Texas A&M AgriLife

A newly developed fertilizer system will provide nutrition to engineered cotton crops worldwide and a deadly dose to weeds that are increasingly herbicide resistant, according to a Texas A&M AgriLife Research study.

The new system applies phosphite to cotton crops engineered to express a certain gene — a gene that makes cotton able to process the phosphite into nutrition while the same compound suppresses weeds that are unable to use it, researchers said. Continue reading

Texas A&M scientist is among team to prove royalty among termites

by Steve Byrnes, Texas A&M AgriLife

Termites! Just the insects’ common name can strike fear in the hearts of most any homeowner, but a recently published work could go a long way in quelling some of those fears, said one of the authors.

Dr. Ed Vargo, Endowed Chair in Urban and Structural Entomology at Texas A&M University, College Station, is among a team of scientists who recently published “Identification of a Queen and King Recognition Pheromone in the Subterranean Termite Reticulitermes,” in the scientific journal Proceedings of the National Academy of Sciences http://www.pnas.org/content/early/2018/03/15/1721419115 Continue reading

Producers might hear a term from the past when they begin looking for solutions to treat the sugarcane aphid in sorghum, according to a Texas A&M AgriLife Extension Service specialist.

“We are revisiting chemigation for insect pest management,” said Dr. Ed Bynum, AgriLife Extension entomologist in Amarillo, while speaking at the High Plains Irrigation Conference in Amarillo recently. Continue reading

Outcrossing between johnsongrass, sorghum studied

Dr. Muthu Bagavathiannan, Texas A&M AgriLife

Johnsongrass and sorghum might be considered “kissing kin,” but a Texas A&M AgriLife Research team wants to know if there is more going on in the grain sorghum production fields and bar ditches of South and Central Texas than meets the eye.

Dr. Muthu Bagavathiannan, weed scientist; Dr. Bill Rooney, sorghum breeder; and Dr. Patricia Klein, sorghum geneticist and molecular biologist, all with AgriLife Research in College Station, have teamed up to study gene flow between sorghum and johnsongrass. Continue reading

Exotic snail poses threat in Louisiana and Texas

In Delta Farm Press

The apple snail, an exotic pest causing problems for Louisiana and Texas rice and crawfish operations, likely became established as a result of aquarium owners dumping the large snails.

The pests pose a double threat — they have a big appetite for vegetation, according to specialists at Louisiana State University. They also clog crawfish trap openings and tunnel through rice levees. Continue reading

Win the war against weeds in warm-season pastures

by Adam Russell, Texas A&M AgriLife

Weeds in warm-season pastures can be an annual battle, and producers should prepare their spray equipment to win the war, said a Texas A&M AgriLife Extension Service expert.

Now is a good time to calibrate equipment and reflect on the previous year’s weed and pest insect issues to apply successful treatments to warm-season pastures, said Dr. Vanessa Corriher-Olson, AgriLife Extension forage specialist, Overton.  Continue reading

Hit the Target website a tool for producers on both sides of auxin training

by Kay Ledbetter, Texas A&M AgriLife

While cotton and soybean producers across Texas are getting the do’s and don’ts for applying new chemical formulations to their crop, the education is being extended to producers with sensitive or susceptible crops to protect their investments.

Texas A&M AgriLife Extension Service personnel have more than 70 meetings planned to train producers on working with the new auxin herbicide technology in cotton and soybeans as a part of label requirements, said Dr. Scott Nolte, AgriLife Extension state weed specialist in College Station.
