Mechanism

• Group 1B: Organophosphates

Hazards

• Caution

Group 1B: Organophosphate

How do they work?

• Organophosphates bind irreversibly to acetylcholinesterase (AChE)

• When AChE is inhibited, acetylcholine builds up, causing constant nerve firing

What pesticides are in this group?

• Acephate (Orthene)

• Dimethoate (Cygon)

• Malathion

• Phosmet (Imidian)

Group 3: sodium channel modulators (Pyrethroids)

How does it work?

• bind to sodium-gate nerve channels inside the insect

• nerve channels never stop opening, leading to constant muscle twitching and death

What insecticides are in this group?

• Bifenthrin (Talstar)

• Cyfluthrin (Baythroid, Tempo)

• Fluvalinate (Maverick)

• Lambda-Cyhalothrin (Demand)

• Lambda-Cyhalothrin (Scimitar)

• Permethrin (Amush, Pounce)

Group 1A: Carbamates

How does it work?

• Carbamates bind irreversibly to acetylcholinesterase (AChE)

• When AChE is inhibited, acetylcholine builds up, causing constant nerve firing, paralysis, and death

What pesticides are in this category?

• Carbayl (Sevin)

Group 15: Chitin Biosynthesis Inhibitors

How does it work?

• blocks enzyme production needed to make chitin

• insect cannot form exoskeleton and molt, leading to death

What insecticides are in this group?

• Diflubenzuron

Group 18A:

How does it work?

• work by mimicking ecdysone, the molting hormone in insects. This forces premature or incomplete molting, leading to deformities, failure to develop, and death.

• effective against larvae or pupae

What insecticides fall in this category?

• Halofenoxide (Mach II)

Group 4A: neonicotinoids,

How does it work?

• work by binding to nicotinic acetylcholine receptors (nAChRs) in the insect nervous system. This causes overstimulation of nerve signals, leading to paralysis and death.

• YOU CANNOT USE THESE ON BLOSSOMING FLOWERS

What pesticides fall under this category?

• Imidacloprid (Merit)

Group 5: Nicotinic Acetylcholine

receptor agonists (allosteric)

(not group 4)

How does it work?

• similar to Group 4, but they bind at a different site (allosteric site) on the production enzyme

What insecticides fall under this category?

• Spinosad (Conserve)
