Products Description
Piperonyl butoxide (synergist ether) can enhance the insecticidal activity of pyrethrins, various pyrethroids, rotenone, and carbamate insecticides. It also improves the insecticidal performance of compounds such as fenitrothion, dichlorvos, chlordane, triclofenac, and atrazine, and exhibits a synergistic effect that helps increase the stability of pyrethrum extracts.
When tested against house flies, this product shows a stronger synergistic effect with permethrin than octachlorodipropyl ether. However, it does not enhance the knockdown effect of cypermethrin on house flies.
In mosquito coil applications, it shows no synergistic effect on allethrin and may even reduce its effectiveness.

Product Application
It is used to control insects that occur during the storage of grains such as rice, wheat, and beans, including pests like grain weevils.
It is commonly used in combination with pyrethrin insecticides to achieve a strong synergistic effect. When pyrethrin is used alone (for example, against house flies), the mortality rate is about 46%. However, when combined with this product (30 mg + 400 mg formulation), the killing rate can increase to 92%.
Typically, this product is mixed with pyrethrin at a ratio of about 1:10 to prepare 0.05%–0.2% emulsions or powders. After application, the residual effect can provide insect-repellent activity for approximately 1 to 10 months.
According to Japanese regulations, it may be used on cereals with a maximum residue limit of 0.024 g/kg (based on this product). An example of a compound insecticide formulation includes 1.2% of this product, 0.08% pyrethrins, and 98.72% inert minerals, with approximately 120 g applied per 60 kg of grain for spraying.
