U of A Weed Science Team Wins 2021 Regional Championship

All five team members placed in the top 10 individually as the U of A weed science team captured first place in the Southern Weed Science Society Weed Contest in early August in Stoneville, Mississippi.

Arkansas edged Virginia Tech University by two-tenths of a point in the closest finish in SWSS history.

In individual standings, Grant Lawson Priess finished first as the top overall scorer. He also won the herbicide symptomology category.

Mason Castner was second overall, Pamela Carvalho-Moore was sixth, Tristen Avent eighth and Maria Zaccaro 10th.
