The PNN is operated by WSU's Pesticide Information Center for the Washington State Commission on Pesticide Registration. The PNN is designed to distribute pesticide registration and label change information to groups representing Washington's pesticide users. The material below is a summary of the information distributed on the PNN in the past month.
Our office operates a web page called PICOL (Pesticide Information Center On-Line). This provides a label database, status on registrations, and other related information. PICOL can be accessed on URL http://picol.cahe.wsu.edu or call our office, (509) 372-7492, for more information.
