Chlorpyrifos is a broad spectrum insecticide, a chemical used to kill a wide variety of insects and is used in a broad spectrum of crops such as citrus, cotton, almonds, and alfalfa to name a few.  In Citrus, it targets 14 pests and is the key for controlling the liquid feeding ants that protect hemipterans, such as Asian Citrus Psyllid. Chlorpyrifos (Label name: Lorsban) lands in the organophosphates class, which California Department of Pesticide Regulation (DPR) has identified as a potential human health and environmental risk.

Effective July 1, 2015, DPR has designated chlorpyrifos a California restricted material, which means one will have to obtain a restricted materials permit from their County Agriculture Commissioner. To learn more about how this change will affect the local citrus industry please join us at our Free Breakfast IPM Meeting hosted by UCCE, UC IPM, and Citrus Research Board on September 15, 2015 at the San Diego Farm Bureau in Escondido from 8:00 AM – Noon. Hot Breakfast and Coffee will be served at 8:00 AM.
