WSSA Recognizes Outstanding Student Weed Scientists

For Immediate Release (Click Here for PDF Version)

WESTMINSTER, Colorado – March 15, 2018 – Today the Weed Science Society of America (WSSA) announced it has recognized nearly three dozen students from 19 universities for outstanding research-related presentations and proposals.

During the Society’s recent annual meeting, 27 students in Master’s and Ph.D. programs were honored for posters and oral presentations summarizing their weed science research. The topics ranged from basic weed biology and ecology to the evolution of herbicide resistance. 

WSSA also has honored nine undergraduate students with research awards designed to nurture their interest in weed science.

“It is clear from the quality of the posters, presentations and research proposals we reviewed this year that the next generation of weed scientists is well prepared and already making its mark,” says Marty Schraer, a research scientist at Syngenta and co-chair of the WSSA awards committee. “We can’t wait to see what they will accomplish in years to come.”

Both graduate and undergraduate award winners are listed below.
