2013 Weed Resistance Management (WRM) in Non-Crop Industrial, Turf and Ornamental Sites

This is an online, accredited continuing education course on the topic of weed resistance management for men and women who work in the industrial, turf and ornamental markets (IT&O). 

It is accredited for all California Department of Pesticide Regulation licensing categories:  PCAs, Qualified Applicators, Private Applicators/County Permit Holders and Aerial Applicators.
Purpose of this continuing education course is to give you an overview of important management practices that can help avoid or delay selection for herbicide-resistant weeds and thus prolong the efficacy of key herbicides. We will begin with a brief overview of common weed types and herbicide modes of action, followed by factors that can influence the development of resistant weed populations and how to help delay or manage its occurrence in golf courses, roadsides, sports fields, and rights-of-way. Once you have successfully completed this course on-line, you will receive 2 hours of Continuing Education Credit.
