Land-grant universities release new guide for managing insecticide resistance

The Insecticide and Miticide Mode-of-Action Field Guide, is now available online through the University of Tennessee Institute of Agriculture.

A new field guide developed through a multistate collaboration gives growers practical guidance on how insecticides and miticides work, how resistance develops and how to plan effective product rotations.

The Insecticide and Miticide Mode-of-Action Field Guide, is now available online through the University of Tennessee Institute of Agriculture. The guide was revised and expanded over several years by scientists with Clemson University, the University of Tennessee and the SePRO Corporation.

Zee Ahmed, who is stationed at Clemson’s Pee Dee Research and Education Center near Florence, South Carolina, is among the guide’s authors, along with William Klingeman and Midhula Gireesh of the University of Tennessee and Juang Chong of SePRO.

“The guide explains how growers can use Insecticide Resistance Action Committee (IRAC) classifications to select products and plan rotations based on their modes of action,” Ahmed said. “It covers turfgrass, nursery, greenhouse, interiorscape and landscape systems. It is designed to help growers make informed treatment decisions, reduce resistance pressure and strengthen integrated pest management programs.”

The publication also highlights the work of NCERA 224. For information, read The Insecticide and Miticide Mode-of-Action Field Guide.

The publication supports Ahmed’s USDA Specialty Crop Block Grant project, Comprehensive guidelines for chemical management of arthropod pests and pathogens on ornamental plants: a resource for nurseries, greenhouses and landscapes in South Carolina.
