Weed Science Society of America

The Weed Science Society of America is a nonprofit, learned society focused on weed science. It was founded in 1956. The organization promotes research, education, and extension outreach, provides science-based information to the public and policy makers, and fosters awareness of weeds and their impact on both managed and natural ecosystems. President for 2018-19 is Scott Senseman from the University of Tennessee.
WSSA has started the International Survey of [Herbicide Resistant Weeds] initiative to collect herbicide resistances. The WSSA classifies all herbicides by the mode of action.
In 2017, WSSA began a partnership with Cambridge [University Press] to continue publication of the three WSSA journals: Weed Science , Weed Technology, and Invasive Plant Science and Management.
