Dual Active Chemistry and Synergistic Modes of Action
This combination blends Pyriproxyfen (an insect growth regulator) with Bifenthrin (a synthetic pyrethroid) in an emulsifiable concentrate.
Pyriproxyfen mimics natural juvenile hormones, suppressing embryogenesis in insect eggs and preventing nymphs from metamorphosing into viable adults.
Bifenthrin acts on voltage-gated sodium channels in insect nerve membranes, delivering immediate contact knockdown and behavioral repellency.
- Pyriproxyfen (10% EC): Juvenile hormone mimic acting as an ovicide and nymphal molt inhibitor
- Bifenthrin (10% EC): Synthetic pyrethroid providing rapid contact knockdown and acaricidal mite kill
- Complete life-cycle control: Destroys eggs, nymphs, and adult insects simultaneously
Target Pests and Approved Crop Applications
The combination is registered across cotton, chilies, tomatoes, and commercial cash crops.
It is especially recognized for controlling destructive whitefly (Bemisia tabaci) epidemics that transmit cotton leaf curl virus and tomato yellow leaf curl virus.
- Cotton: Controls whitefly eggs, nymphs, and adults alongside bollworm complexes
- Chilies and vegetables: Manages thrips, whiteflies, and phytophagous spider mites
- Pulses: Suppresses pod borers and foliage-feeding lepidopteran larvae
Application Guidelines, Mixing, and Safety
Dilute the emulsifiable concentrate in clean water with continuous agitation and apply using high-volume knapsack sprayers.
Ensure thorough spray coverage of lower leaf surfaces where whitefly nymphs and eggs reside.
Avoid spraying during crop blooming hours to protect foraging honeybees.
- Foliar wetting: Spray both upper and lower canopy surfaces until leaves are evenly coated
- Pollinator safety: Avoid application during crop bloom when honeybees are actively foraging
- Personal protection: Wear chemical-resistant gloves, protective clothing, and eye goggles during preparation

Common questions
What chemicals are in Pyriproxyfen 10% + Bifenthrin 10% EC?
It contains Pyriproxyfen (an insect growth regulator) and Bifenthrin (a synthetic pyrethroid and acaricide) in an emulsifiable concentrate.
Why is this combination effective against whiteflies?
Bifenthrin knocks down adult whiteflies instantly, while Pyriproxyfen sterilizes eggs and halts nymphal development, collapsing the population.
Does this formulation control spider mites?
Yes, Bifenthrin possesses strong acaricidal activity that effectively suppresses phytophagous spider mites.
