Product Description of Piperonyl Butoxide 95% CAS#51‑03‑6
Piperonyl butoxide, also known as synergist ether, is capable of amplifying the insecticidal potency of pyrethrins, diverse pyrethroid compounds, rotenone and carbamate insecticides. It also boosts the insecticidal performance of active ingredients including fenitrothion, dichlorvos, chlordane, triclofenac and atrazine, and delivers synergistic benefits that improve the stability of pyrethrum extracts.
In bioassays targeting house flies, this ingredient demonstrates more potent synergism with permethrin compared to octachlorodipropyl ether. Nevertheless, it fails to strengthen the knockdown activity of cypermethrin against house flies.
For mosquito coil formulations, it presents no synergistic effect toward allethrin and may even weaken its insecticidal efficacy.

Product Application of Piperonyl Butoxide 95% CAS#51‑03‑6
It is applied for the management of insect pests arising during grain storage for rice, wheat, beans and other cereals, with granary weevils as one of the target pests.
It is frequently blended with pyrethrin‑based insecticides to generate remarkable synergistic action. Pyrethrin used singly achieves roughly 46% mortality against house flies for instance; once combined with this product in the formulation of 30 mg plus 400 mg, the kill rate can rise to 92%.
This synergist is generally compounded with pyrethrin at a ratio around 1:10 to manufacture emulsions or dust formulations ranging from 0.05% to 0.2%. Upon treatment, its residual effect delivers insect repellency lasting roughly 1 to 10 months.
Under Japanese regulatory standards, it is permitted for use on cereal grains with a maximum residue limit of 0.024 g/kg calculated on this active substance. A representative compound insecticide formulation contains 1.2% piperonyl butoxide, 0.08% pyrethrins and 98.72% inert mineral carriers, with a recommended spray dosage of approximately 120 g for every 60 kg of stored grain.
