Are you Rotating Chemicals Correctly By The Class Mode of Action? If I ask most technicians if they are rotating chemicals correctly most would say they, but when they analyze how they are rotating they are shocked to find out they are not.

When I teach at the extension service the on Best Management Practices to landscapers, municipal workers and pest control technicians. I always ask this question. What is IPM? Most of the pest control people in the room almost always answer with rotating chemicals. And that would be wrong, rotating chemicals is not part of IPM but it is part of basic sound pest management practices, so why do so few people understand it and even fewer really practice it.
Most of us have not been taught to rotate chemical and if we have we have rotated with a different active ingredient only to be rotating within the same class, but in order to prevent resistance to a specific type of chemical to a completely different class with a completely different mode of action.
When talking to pest control technicians I find that few understand the mode of action.
To understand this lets discus the two most popular modes of action on the market for PMP’s.
Pyrethroids mostly known as repellents.
Class 3 Sodium Channel Modulators
Acrinathrin, Allethrin, Bifenthrin, Bioallethrin, Bioallethrin S-cyclopentenyl, Bioresmethrin, Cycloprothrin, Cyfluthrin, Cyhalothrin, Cypermethrin, Cyphenothrin, Deltamethrin, Empenthrin, Esfenvalerate, Etofenprox, Fenpropathrin, Fenvalerate, Flucythrinate, Flumethrin, Halfenprox, Kadathrin, Phenothrin, Prallethrin, Pyrethrins, Pyrethrum, Resmethrin, Silafluofen, Tefluthrin, Tetramethrin, Tetramethrin, Tralomethrin, Transfluthrin, alpha-Cypermethrin, beta-Cyfluthrin, beta-Cypermethrin, Allethrin, gamma-Cyhalothrin, lambda-Cyhalothrin, tau-Fluvalinate, theta-Cypermethrin, zeta-Cypermethrin.
There are 41 active ingredients in the Pyrethroids Class
Plus DDT and Methoxychlor
Neonicotinoids more modern known as non-repellents.
Class 4 Nicotinic Acetylcholine Receptor Competitive Modulators (NACHR).
Acetamiprid, Clothianidin, Dinotefuran, Imidacloprid, Nitenpyram, Thiacloprid, Thiamethoxam.
7 Active ingredients in the Neonicotinoid line but there is a total of 4 of types (NACHR) in the Class
Nicotine the active ingredient is Nicotine .
Sulfoximines with the active ingredient Sulfoxaflor.
Butenolides active ingredient Flupyradifurone.
The danger of combination products is that they combine 2 active ingredients with 2 classes together and now what do you rotate with?
What is the mode of action?
Did you know that there 29 classes of pesticides with hundreds of active ingredients? Do you want to know how a pesticide works to control by the mode of action a pest and what chemical active ingredients are in those classes?
