Students Sharpen Skills in National Weed Science Contest

This summer, students were tested on such weed science skills and more in the 2023 Weed Science Society of America (WSSA) National Weed Science Contest held at Bayer's research farm in Union City, Tennessee. The contest provides opportunity for undergraduate and graduate students with future in agriculture and related disciplines.

WESTMINISTER, Colo., Oct. 30, 2023 /PRNewswire-PRWeb/ -- Can you identify a weed species in any growth stage? Or, know all aspects of sprayer calibration, such as required spray volume?

This summer, students were tested on such weed science skills and more in the 2023 Weed Science Society of America (WSSA) National Weed Science Contest held at Bayer's research farm in Union City, Tennessee. The contest provides opportunity for undergraduate and graduate students with future in agriculture and related disciplines.

The weed science areas students exhibited during this contest included:

•      Weed identification. Students needed to correctly identify 25 weed species in any stage of development—including seed samples.
•      Sprayer calibration. Students took a written test regarding all aspects of sprayer calibration, such as required spray volume, amount of herbicide needed per gallon or liter, nozzle nomenclature and selection, sprayer pressure, droplet size, boom height, and drift reduction techniques. This portion also included a team activity where students calibrated a sprayer.
•      Herbicide identification. Students identified 10 different herbicides based on visual symptoms and selectivity when applied to crops and weeds.
•      Weed control issues faced by farmers and other weed management practitioners. Students evaluated a crop production problem in areas such as weed management and recommended an effective solution. Examples included herbicide injury, weed resistance, or agronomic errors.

"This contest was a great educational opportunity for students to showcase their weed science knowledge," says Matthew Wiggins, WSSA student contest chair. "Students did this not only through written tests, but also in hands-on tests that tackled real-world weed management problems and challenges."

Regional awards sponsored by the Northeastern Weed Science Society, North Central Weed Science Society, Southern Weed Science Society, and Western Society of Weed Science were also given to students. All in all, 153 graduate students and 64 undergraduate students on 54 teams from 27 universities gleaned many hours of training under the guidance of university weed scientists. Top team and individual winners are shown below.
