Whitefly is one of the most damaging sucking pests in chilli, feeding on sap and secreting honeydew that leads to sooty mould, while also transmitting Chilli Leaf Curl Virus. Because whitefly populations build resistance quickly and different life stages respond to different chemistries, growers typically rotate between egg/nymph-targeting IGRs and adult-knockdown insecticides. Here are fourteen proven solutions.
1. Beta-cyfluthrin 8.49% + Imidacloprid 19.81% OD
This dual-action oil dispersion combines a pyrethroid (Beta-cyfluthrin) that disrupts nerve function on contact with a systemic neonicotinoid (Imidacloprid). Together they give fast knockdown and extended protection against whitefly, aphids, and jassids in chilli.
Product Recommendations
2. Flonicamid 50% WG
Flonicamid is a systemic pyridinecarboxamide insecticide that works differently from neonicotinoids — it disrupts feeding behaviour rather than the nervous system, causing pests to stop feeding and eventually starve. It's especially useful for reducing virus transmission since whitefly stop probing almost immediately.
Product Recommendations
3. Acephate 50% + Imidacloprid 1.80% SP
This combination pairs a systemic organophosphate (Acephate) with a neonicotinoid (Imidacloprid), giving both translaminar and systemic action against whitefly and other sucking and chewing pests in chilli.
Product Recommendations
4. Carbosulfan 25% EC
Carbosulfan is a carbamate insecticide with contact and stomach action, effective against sucking and chewing pests including whitefly. It's metabolised in the plant to carbofuran, giving extended residual activity.
Product Recommendations
5. Pyriproxyfen 5% + Diafenthiuron 25% SE
This combination pairs an insect growth regulator (Pyriproxyfen) with a metabolic inhibitor (Diafenthiuron), giving a one-shot solution across all whitefly life stages — eggs, nymphs, and adults. Pyriproxyfen prevents egg hatching and causes adult sterility, while Diafenthiuron gives quick knockdown.
Product Recommendations
6. Dimpropyridaz 120 g/l SL
Dimpropyridaz is a newer-generation insecticide from BASF's Axalion Active technology, with a novel mode of action that disrupts insect chordotonal organs, causing rapid feeding cessation. It's registered for whitefly and aphids in chilli with a favourable safety profile for beneficial insects.
Product Recommendations
7. Cyantraniliprole 7.3% + Diafenthiuron 36.4% SC
This combination pairs a diamide (Cyantraniliprole) that disrupts pest muscle function with a metabolic inhibitor (Diafenthiuron), giving systemic, contact, stomach, and translaminar action. It's specifically registered for whitefly, thrips, aphids, and mites in chilli.
Product Recommendations
8. Pyriproxyfen 5% + Fenpropathrin 15% EC
This combination pairs an insect growth regulator (Pyriproxyfen) with a fast-acting pyrethroid (Fenpropathrin), giving both life-cycle disruption and quick knockdown of adult whitefly in chilli.
Product Recommendations
9. Fenpropathrin 30% EC
Fenpropathrin is a synthetic pyrethroid that interferes with voltage-gated sodium channels in the insect nervous system, causing rapid paralysis. It offers broad-spectrum control of whitefly, thrips, and mites in chilli through contact and ingestion action.
Product Recommendations
10. Pyriproxyfen 10% + Bifenthrin 10% EC
This combination pairs a growth regulator (Pyriproxyfen) with a pyrethroid (Bifenthrin), offering comprehensive control across all whitefly life stages along with quick knockdown of adults and other sucking pests in chilli.
Product Recommendations
11. Fluxametamide 5.81% + Bifenthrin 5.81% EC
This is a newer-generation dual-action insecticide combining a novel isoxazoline (Fluxametamide) that disrupts GABA-gated chloride channels with a pyrethroid (Bifenthrin) that disrupts sodium channels. Together they control both sucking and chewing pests, including whitefly, with strong rainfastness.
Product Recommendations
12. Pyriproxyfen 10% EC
Pyriproxyfen is an insect growth regulator that mimics juvenile hormone, disrupting moulting and preventing eggs from hatching. It targets all life stages of whitefly in chilli without directly killing adults, instead rendering them sterile.
Product Recommendations
13. Pyriproxifen 8% + Diafenthiuron 30% SE
This higher-concentration combination of Pyriproxyfen and Diafenthiuron offers long-lasting control of 12–15 days, managing all three whitefly life stages while also helping contain the spread of Chilli Leaf Curl Virus and suppressing yellow mites.
Product Recommendations
14. Hexythiazox 3.5% + Diafenthiuron 42% WDG
This combination pairs a mite growth regulator (Hexythiazox) with a metabolic inhibitor (Diafenthiuron), giving dual-mode, non-systemic control with contact and stomach action. It's specifically formulated for chilli, controlling mites, whitefly, aphids, and thrips together.
