Dr. Michael Scharf of Purdue University presented a comprehensive overview of insecticide classification and mode of action designed to strengthen pest management professionals' understanding of how their chemical tools work. Scharf framed the practical importance of this knowledge around six themes: applicator and customer safety, accurate interpretation of trade literature, pollinator protection, resistance management, product sustainability, and the ability to design customized applications through situational pest management.
The presentation systematically covered five neurotoxic insecticide classifications — sodium channel agents, chloride channel agents, acetylcholine receptor agents, acetylcholinesterase inhibitors, and combination products — followed by four non-neurotoxic classifications including diamides, insect growth regulators, inhibitors of energy production, and cuticle dehydrating dusts. Scharf concluded with practical factors affecting insecticide performance, resistance management strategies, and a Q&A session moderated by Dr. Suiter.
