WARNING
Mode of Action
Acetylcholinesterase Inhibitor
Carbaryl reversibly inhibits acetylcholinesterase (AChE) in insect nerve synapses. Unlike organophosphates, carbamylation of AChE by carbaryl is reversible — the enzyme can spontaneously reactivate over time. Despite this reversibility, the acute disruption of cholinergic neurotransmission is sufficient to cause insect paralysis and mortality at label rates.

Interval
7 – 14 days

Resistance Management
Medium resistance risk. Carbaryl resistance has been documented in several insect species via esterase-mediated detoxification. Rotate with pyrethroids, diamides, or spinosyns. AChE inhibitors (IRAC 1A and 1B) share cross-resistance pathways.
