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

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
