Estimated Cost of the Withdrawal of the Insecticide Chlorpyrifos for Six Major California Crops

In May 2019, the CA 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.

Implications of Disrupting a Perennial Crop Replanting Cycle: The Brazilian Sugarcane Example

Brazilian sugarcane yields declined sharply in 2011, ending a decade-long expansion of the industry. In the aftermath of the 2008 financial crisis, credit-constrained farmers replanted fewer sugarcane fields, leading to an increase in the average age of canes and a decline in yield several years later. Had average age remained constant over this period, industry revenues would have been around 10% higher in 2011 and 2012. This example shows how interruptions to the regular replanting schedules of a perennial crop can have production effects years into the future.

Economic Value of the Herbicide Dacthal for Brassica and Allium Crops in California

California review of the herbicide dacthal triggered by the requirements of California’s Pesticide Contamination Prevention Act was conducted in 2018. This article estimates the economic effects a cancellation of dacthal’s California registration would have on brassica and allium crops. Statewide net revenue losses for broccoli, dry onion, and cabbage, the largest users of dacthal, are estimated at $25.4 million: $17.9 million for broccoli, $2.4 million for cabbage, and $5.1 million for onion.
