New UTIA center to provide weed diagnostic tests

October 10, 2016

KNOXVILLE, Tenn. -- What do golf course superintendents, farmers and weekend gardeners have in common? For one, they all share a strong dislike of weeds. Whether you're a professional or amateur, nothing can ruin your day like a weed. Worse yet, no matter how you try to control this pesky green invader, it just keeps coming back for more. Fortunately, there is help available to help you get things under control.

The University of Tennessee Weed Diagnostics Center (UTWDC) is there to help identify weeds and screen them for herbicide resistance. This initiative, supported by UT AgResearch and UT Extension, provides end-users with diagnostic tests tailored to weeds in a variety of settings.

"Our aim is to provide a broad spectrum of services to both professional and consumer clientele," said Dr. Jim Brosnan, Associate Professor of Turfgrass Weed Science at the University of Tennessee Institute of Agriculture. "Our tests are tailored to weeds of crop production systems as well as turf, ornamentals and urban landscapes," he said.

Brosnan heads up UTWDC and sees it as a valuable service not only in Tennessee but across the United States as well. He says that it's important to have weeds tested to help keep them under control and then use the diagnostic results to implement optimal management strategies.

"All UTWDC test results are complimented with research-based control recommendations to promote proper weed management in the field," said Brosnan. "We'll also complement the ongoing disease and plant diagnostic efforts at UTIA's Soil, Plant and Pest Center in Nashville," he said.

Employing both whole-plant and molecular methods, specialists at UTWDC provide a wide range of diagnostic services from basic weed identification to herbicide resistance tests using DNA screening. "We're looking to provide an all-inclusive service for our clients that's cost-effective and helps them conserve financial and technological resources," said Brosnan.

Through its mission of research, teaching and extension, the University of Tennessee Institute of Agriculture touches lives and provides Real. Life. Solutions.

#535 Superior
Apologies for the delay getting this week's episode out! A technical glitch slowed us down, but all is once again well. This week, we look at the often troubling intertwining of science and race: its long history, its ability to persist even during periods of disrepute, and the current forms it takes as it resurfaces, leveraging the internet and nationalism to buoy itself. We speak with Angela Saini, independent journalist and author of the new book "Superior: The Return of Race Science", about where race science went and how it's coming back.
