Seminar Description

The pesticide industry is projected to be over 300 billion by 2025. Companies across the globe are competing to produce products that meet the growing demand and maintain legacy products. Environmental Protection Agency (EPA) product approval is key to developing and maintaining pesticide products in the United States including herbicides, insecticides and rodenticides. Knowing how the regulatory process works is a key component to product success both in terms of time and profit.

The workshop will provide a practical approach to getting pesticide products approved and keeping them in the market post approval, while avoiding common pitfalls and challenges faced along the way. The workshop is designed to be interactive with case studies, and an opportunity for participant interaction and networking.

This course provides 13 contact hours of veterinary continuing education as certified by Kansas State University's College of Veterinary Medicine.
