Dow AgroSciences Statement on Chlorpyrifos and California Proposition 65

11/29/2017 -

Dow AgroSciences strongly disagrees with the California Developmental and Reproductive Toxicity Identification Committee (DART IC) decision to list chlorpyrifos under Proposition 65. Specifically, chlorpyrifos has not been “clearly shown by scientifically valid testing according to generally accepted principles to cause developmental toxicity.” Simply put, the data do not support listing. Chlorpyrifos has been studied extensively by many regulatory agencies around the world, and none have concluded that it causes developmental toxicity within the meaning of Proposition 65.

Chlorpyrifos is a conventional crop protection product designed to control insects such as ants, rootworms and other pests that harm crops. Since entering the market in 1965, chlorpyrifos has become one of the most widely used crop protection solutions in the world. It is authorized for use in about 100 countries – including Australia, Brazil, Canada, China, Italy, Japan, Mexico, New Zealand, Poland, Russia, South Africa, and the United States, where it is registered for the protection of essentially every crop, including alfalfa, almonds, citrus, cotton, walnuts, corn, soybeans, and wheat, among many others.

The toxicological database for chlorpyrifos is one of the more extensive for any regulated chemical. More than 4,000 studies and reports have been conducted that have shown that chlorpyrifos can be used safely to protect our food supply and human health. Strict federal, state and local restrictions govern the use of this important crop protection tool.

At Dow AgroSciences, we strongly believe there is not sufficient evidence to support the State’s decision. This decision may have a significant negative impact on California growers’ ability to produce healthy crops and on the State’s $40 billion agriculture industry. As such, we intend to evaluate all potential actions in response to this decision and vigorously support growers.
