Abstract

In May 2019, the California Department of Pesticide Regulation (DPR) initiated the cancellation of the pesticide chlorpyrifos. This article estimates the economic effects of cancellation on six major California crops. Statewide annual revenue losses are estimated at $11.5 million, averaged across acreage and pesticide use for three base years (2015–2017): $1.6 million for alfalfa, $0.6 million for almonds, $1 million for citrus, $7.1 million for cotton, $4.3 million for grapes, and $3.2 million for walnuts. In addition, gross revenue losses due to reduced cotton yields are estimated to be $6.3 million. Importantly, estimated losses are for only six crops. The total cost to California agriculture will be greater.
