Students Test Their Skills in Regional Weed Science Contests

WESTMINSTER, Colorado – September 15, 2021 – This summer Weed Science Society of America (WSSA) affiliates in the North Central and Southern regions gave nearly 100 students from 18 universities a chance to test their weed science know-how. Both organizations sponsored hard-fought competitions featuring multiple challenges – from identifying weeds at varying stages of growth to troubleshooting weed control issues faced by farmers in the field.

“For many students, the contests culminated months or even years of study,” says WSSA board member Delaney Foster, a graduate research assistant at The University of Tennessee and a winner in the Southern Weed Science Society contest. “Participants get hands-on experience in many of the practical aspects of weed science, including an opportunity to practice problem-solving skills that will benefit them as they enter the workforce.”

Details about the two events and the winners are below.


The 2021 North Central Weed Science Society contest was hosted by North Dakota State University in Fargo. Sixty-one graduate and undergraduate students from 10 universities participated.
