SB 950 was passed creating the Birth Defect Prevention Act. Purpose was to prevent pesticide induced abortions, birth defects and infertility.

June, 1987
List of 200 priority chemicals is determined by the Department of Pesticide Regulation (DPR) and published into state regulations.

July, 1999
First mitigation actions begin to take place by DPR. As an example, cotton defoliant Tribufos (DEF/Folex) has pre-harvest interval increased to address worker exposure risk.


Additional mitigation beyond current practices is a strong possibility, especially with worker exposure. All chemicals used on cotton that have been reviewed under this Act, have had requirements for additional mitigation, including Ovasyn, Eptam and DEF/Folex.

Of the 200 active ingredients listed, 53 active ingredients are no longer registered in California. Six (6) registrations have been suspended by DPR under authority of this Act. Of the remaining active ingredients, 47 are contained in products used on cotton including the following:

Accelerate Dibrom Lorsban Ridomil

California Food and Agriculture Code 13129(a).

California Code of Regulations, Title 3, Division 6, Chapter 2, Subchapter 1,
Article 3, 6198.5(a).
