Lorenz provides leadership and direction for the development and implementation of integrated solutions to pest problems encountered in row crop agriculture. This is accomplished by stimulating and facilitating the development of interdisciplinary IPM Extension programs across departments or sections, among public agencies, and between the public and private sectors. Primary responsibilities include major row crops but I also work in stored grains, pollinators, and invasive pests.

 Integrated Pest Management: Primarily major row crops; and stored grains, pollinators, and invasive pests.

Ph.D.   University of Arkansas  1995   Entomology
