Weeds Across Borders (WAB), a biennial trilateral conference covering the interests of professionals and organizations involved in North American weed management and regulation, took place during the first week of June 2010 at the National Conservation Training Center in Shepherdstown, West Virginia. Composed of an affiliation of organizations from Canada, Mexico, and the United States with a common interest in sharing information and promoting weed management throughout North America, the conference has rotated between the three countries since its inception in 2002.

Over 100 speakers and attendees traveled from 27 states, six provinces, and five countries to form partnerships between government agencies, universities, industry, non-governmental organizations, and volunteer organizations.
