Whiteflies in tomato are more than an annoying sap-sucking pest — they're the primary carrier of tomato leaf curl virus, which can stunt plants and slash yield long before the whitefly population itself looks severe. Tiny and pale, they cluster on the underside of leaves and multiply fast in warm, dry weather. Because resistance builds quickly with repeated use of the same product, rotating between different modes of action, chemical and biological, is the best way to stay ahead of them. Here are 12 verified solutions for whitefly in tomato.
1. Thiamethoxam 12.6% + Lambda-cyhalothrin 9.5% ZC
Combines a systemic neonicotinoid with a fast pyrethroid, giving both quick contact knockdown and longer systemic protection in a single spray.
Product Recommendation
2. Cyantraniliprole 10.26% OD
A newer anthranilic diamide with systemic, contact, and ingestion activity, giving rapid feeding cessation when applied early in the infestation.
Product Recommendation
3. Thiamethoxam 25% WG
A systemic neonicotinoid absorbed by the plant, giving quick knockdown and lasting protection against whitefly feeding on treated leaves.
Product Recommendation
4. Diafenthiuron 50% WP
Works through contact and ingestion, paralysing whitefly on exposure so the pest stops feeding and dies within a few days.
Product Recommendation
5. Flonicamid 50% WG
A selective feeding blocker that stops whitefly from feeding almost immediately, causing it to starve, while staying gentle on beneficial insects.
Product Recommendation
6. Imidacloprid 70% WG
A concentrated systemic neonicotinoid effective at very low doses, giving long-lasting protection against whitefly with minimal product used per acre.
Product Recommendation
7. Imidacloprid 17.8% SL
A systemic neonicotinoid readily taken up by the plant, giving strong root-systemic action against whitefly and other sucking pests.
Product Recommendation
8. Spiromesifen 22.90% SC
A contact insecticide-acaricide that targets all developmental stages of whitefly, reducing egg viability alongside killing nymphs and adults.
Product Recommendation
9. Dimpropyridaz 120 g/l SL
A newer chemistry that works on the pest's sensory organs, leaving it uncoordinated and unable to feed or fly, so it eventually dies of starvation.
Product Recommendation
10. Carbofuran 3% CG
A granular carbamate broadcast into the field, giving broad-spectrum, longer-duration control of whitefly and other soil and foliar pests.
Product Recommendation
11. Chlorantraniliprole 8.80% + Thiamethoxam 17.50% SC
An integrated combination that gives broad-spectrum control of whitefly alongside fruit borer and leaf miner, useful when several pests appear together.
Product Recommendation
12. Verticillium lecanii 1.15% WP
A naturally occurring fungus that infects whitefly on contact and grows through its body, killing it over a few days. It's safe for beneficial insects, making it a useful rotation partner in an organic or IPM programme.
