Pesticide Products Expert Witnesses & Blue Book

Pesticide products expert witnesses may opine on fungicides, herbicides, and insecticides. On their website, the Chemical Producers & Distributors Association announces that an updated version of the Pesticide Registration Manual, also known as the “Blue Book,” is now available on EPA’s web site. The manual describes EPA’s review and decision making process for registering a pesticide product and its use. Detailed information for pesticide registrants concerning their responsibilities before, during and after the review process is also included in the manual. EPA is hoping to make available in the near future an electronic version of the “Blue Book” in PDF format. The Agency intends to make subsequent updates to individual chapters of the manual as needed. The “Blue Book” may be accessed at
