Classical biological control of weeds is an important management tool to control invasive species across large landscapes. This webinar intends to provide a brief history of biocontrol to include the processes in place for testing, screening, evaluating and approving introductions in the U.S. Additionally, accessibility of these agents for private landowners and government agencies will be discussed to include generalities of that process, where they might go to collect biological control agents, tools to identify agents that have proven to be successful in providing management of certain species, and what new ideas are available that landowners may be unaware of.
