The Pesticide Educational Resources Collaborative, not to be confused with the Property and Environment Research Center, has prepared a third edition that covers changes in regulations since 2014 according to an article by Capital Press.
The second edition is available at the EPA website.
The manual is intended as a study guide for those planning to take the Pesticide Applicator Certification Core Exam.
The 2014 edition states on page 51 that restricted-use pesticides (such as PZP) demand special attention because there is reason to believe they could harm humans, livestock, wildlife or the environment even when used according to label directions.
Such as permanent infertility in mares.
Unlawful use of pesticides is discussed on page 39.
The advocates want you to think of PZP as a medication, always referring to the product as a vaccine.
