  1. Over-the-Counter Products - What’s in the Bottle? David J. Shetlar, Ph.D. The “BugDoc” The Ohio State University, OARDC & OSU Extension Columbus, OH © October, 2002, D.J. Shetlar, all rights reserved

  2. Is There Life After Dursban and Diazinon Cancellation? • Food Quality Protection Act (FQPA) continues to review insecticides and miticides. • Organophosphates and Carbamates are major targets for restriction. • Dursban and diazinon NOT canceled, just restricted from residential use, still available for golf courses and nurseries. • Orthene also “voluntarily” withdrawn – Cygon (=dimethoate), Sevin (=carbaryl) and others not being “supported.”

  3. What are the alternatives? • Pyrethroids – broad spectrum insecticides; some with mite suppression; considerable range of activity within group (i.e., they are not all the same!). • Neonicotinoids – broad spectrum; some systemic action; often slow action – best used as preventives; not all are the same! • Spinosyn – moderately broad spectrum, good on caterpillars, spider mites, some leafminers. • Neem (azadirachtin) – moderate spectrum; IGR action. • Oils & Soaps – still there!

  4. Pyrethroids • Sumithrin [Ortho] • Tetramethrin [Ortho] • Resmethrin • Cyfluthrin (=Tempo)[Bayer Advanced Lawn & Garden products] • Permethrin (=Astro, Pounce)[Spectracide] • Bifenthrin (=Talstar) [Ortho & Scotts products] • Deltamethrin [Bonide] • Esfenvalerate (=Asana) [Ortho] • Lambda-cyhalothrin (=Scimitar)

  42. Borer Control Approaches Cultural – Use plants that are not prone to borer attack! Plant health care – plants in good growing conditions can usually repel borer attacks. Avoid Plant Damage – damaged plants are prone to attack. Biological – Usually not effective because they attack after infestation.
