Session Name: Persistent Herbicides in Compost: Identifying the Problem, Exploring Solutions

Session Time: Thursday, January 30, 11:00 AM to 12:30 PM

Presentation Title: Persistent Herbicides in Compost: An Organic Certifier’s Perspective

Presentation Description: Persistent Herbicides are chemical broadleaf weed killers that survive the composting process and continue to negatively affect susceptible plants grown with compost. The four major types of persistent herbicides include: Clopyralid, Aminopyralid, Aminocyclopyrachlor, and Picloram. The purpose of this session is to bring to light the widespread nature of this problem, and encourage open discussion with USCC members on an often taboo subject. In this session, panelists will discuss what persistent herbicides are and the vectors through which they get into compost, along with strategies to control these vectors. We will review testing methods, both in-house and laboratory-based, that can be used to identify the presence of persistent herbicides in finished compost as well as remediation strategies that have been successfully used in the past. We will examine the implications of persistent herbicides in compost for the organic agriculture market . We will highlight the issues for generic persistent herbicides that may be registered for use in a few years, and implications of this event for the composting industry. Finally, we will explore potential markets for contaminated compost. We encourage audience participation.
