Dual Active Modes of Action
Sumiprempt combines an insect growth regulator (Pyriproxyfen, IRAC Group 7C) with a broad-spectrum synthetic pyrethroid (Fenpropathrin, IRAC Group 3A). Pyriproxyfen suppresses embryogenesis, inhibits adult emergence, and sterilizes female insects, while Fenpropathrin delivers rapid contact knockdown of adult pests.
This dual action eliminates mobile adults while halting the reproduction of juvenile whitefly nymphs.
- Cotton: Whitefly (Bemisia tabaci) across egg, nymph, and adult stages, along with bollworm larvae.
- Chilli: Mites, thrips, and fruit borer infestations.
- Egg sterility: Adult females exposed to the spray lay non-viable eggs, dramatically curbing population rebounds.
- Ovicidal & nymphicidal action: Kills developing whitefly nymphs on the lower leaf surface through translaminar movement.
Application Best Practices and Resistance Care
Optimal whitefly management requires applying Sumiprempt at the initial onset of infestation before sooty mold establishes on honeydew deposits.
Thorough spray deposition on the underside of foliage is critical to target sheltered nymphal colonies.
- Calibrate knapsack or tractor-mounted sprayers to deliver a fine mist covering lower canopy leaves.
- Rotate with alternative chemistry classes such as neonicotinoids or diamides to mitigate insect resistance.
- Wear personal protective gear and respect label pre-harvest intervals before picking agricultural produce.

Common questions
What active ingredients constitute Sumiprempt insecticide?
Sumiprempt contains Pyriproxyfen 5% (an insect growth regulator) and Fenpropathrin 15% EC (a synthetic pyrethroid).
Why is Sumiprempt effective against whiteflies in cotton?
It targets all whitefly life stages: Fenpropathrin provides immediate adult knockdown, while Pyriproxyfen sterilizes adults and kills nymphs and eggs.
Can Sumiprempt also control crop mites?
Yes, Fenpropathrin exhibits strong acaricidal properties that control phytophagous mites alongside sucking insect pests.
