Title California Department of Pesticide Regulation Proposes New Restrictions on the Use of 1,3-Dichloropropene
Introduction LA Testing provides environmental testing services to protect workers, the public and the environment from exposure to pesticides and other potential chemical hazards.

Huntington Beach, California, December 12, 2022 

Last month, the California Department of Pesticide Regulation (DPR) announced it had introduced proposed regulations to protect Californians from potential exposure to the pesticide known as 1,3-dichloropropene (1,3-D).

1,3-Dichloropropene is mainly used in farming as a preplant fumigant to kill nematodes and other soil-borne pests. It is an organochlorine compound that dissolves in water and easily evaporates. In California, DPR reports it is used for crops such as carrots, strawberries and sweet potatoes, and is also applied prior to planting almond and walnut trees, raspberries and grape vines.

According to the DPR announcement:

The proposed regulations would expand setbacks from occupied structures, limit application rates, acreage, and allowed application methods, and include more stringent use requirements between November to February when weather conditions can create higher air concentrations following an application. The regulations also propose requirements for lower-emission application methods for tree and vine applications, which have the highest application rates for 1,3-D. 

“Back in 1989, the state of California listed 1,3-dichloropropene as known to cause cancer under Proposition 65,” said Michael Chapman, Laboratory Manager of LA Testing’s Huntington Beach facility. “Exposure to this pesticide is a potential danger for both the public and workers. To protect workers, the Occupational Safety and Health Administration (OSHA) and Cal/OSHA have set a Permissible Exposure Limit (PEL) and the National Institute for Occupational Safety & Health (NIOSH) has a Recommended Exposure Limit (REL). These are all reasons why LA Testing offers laboratory services to identify 1,3-dichloropropene and many other pesticides.”
