Biocontrol Summit
December 2, 2021 @ 11:00 am – 3:00 pm CST
Highlighting and Fostering International Collaborations that Enhance Weed Biocontrol in North America
NAISMA’s virtual Classical Weed Biocontrol Summit, Highlighting and Fostering International Collaborations that Enhance Weed Biocontrol in North America, took place on December 2, 2021, from 11 a.m. – 3 p.m. CT.
The Annual Weed Biocontrol Summit communicates the latest information in weed biocontrol research to North American invasive plant managers, educators, and researchers.
In 2021, we focused on international collaborations, which are a critical component in developing weed biocontrol opportunities for our most troublesome weeds. Without foreign exploration and research and development through international collaborations, weed biocontrol simply would not exist. This year we will hear from international partners spanning five continents that help make biocontrol a readily available weed management tool for North America.
