Forage producers face annual battle with weeds

by Adam Russell, Texas A&M AgriLife

It’s an annual battle to address range and pasture weeds, said a Texas A&M AgriLife Extension Service expert.

Cool-season weeds have fully matured, and warm-season weeds are emerging amid wet spring conditions and creating problems for some forage producers, said Dr. Vanessa Corriher-Olson, AgriLife Extension forage specialist, Overton. Continue reading

Expect invaders as weather gets colder

This post was written for Texas Extension specialists; however, the tips included are applicable to people in all states.

With temperatures dropping, many Texas residents likely will be getting some unwanted guests in their homes around the holidays, according to Texas A&M AgriLife Extension Service pest management experts.

“This time of year, squirrels, as well as raccoons, will try to make nests in attics,” said Janet Hurley, AgriLife Extension program specialist in integrated pest management, Dallas. “Also several species of ants will nest in the walls of homes for warmth and protection.” Continue reading

Extension Team Develops “App” to Identify Weeds in Container Nurseries

A group of plant scientists at NC State University are trying to help ornamental plant growers get to the root of their weed problems.

With herbicide-resistant weeds on the rise, and a zero-tolerance threshold for weed pests in the nursery, Drs. Alexander Krings, Joe Neal and Bridget Lassiter have created a web “app” that helps the nursery owner identify container weeds. Upon completion, WeedIT Mobile could potentially save ornamental plant producers millions of dollars a year in preemergence herbicide and hand weeding costs. Growers currently spend about $550 per acre every year on herbicides, coupled with hand weeding costs at $2,400 to $5,500 per acre every year.

University of Nebraska holds Plant Recognition webinars

A special seminar series on the topic of “Plant Recognition and Identification Technology” will be held later this month at the University of Nebraska-Lincoln. Three well-known speakers will talk about the latest in agricultural automation, computer vision for species recognition, and challenges and opportunities for robotic weeding. Part of the focus of these seminars is to build collaborative relationships in this rapidly advancing field of research.

Please plan on joining experts at Lincoln or online for one or all of the seminars. For information about the seminar series, visit, which has all of the details.
