- Acetylcholinesterase-inhibiting, organophosphate mode of action
Quinalphos is an organophosphate insecticide that inhibits the enzyme acetylcholinesterase, which is responsible for breaking down the neurotransmitter acetylcholine at nerve synapses. This inhibition causes acetylcholine to accumulate, leading to continuous nerve stimulation, paralysis and death of the target pest. Quinalphos is classified under IRAC Group 1B (organophosphates).
