How It Works: Mode of Action
Pyriproxyfen and fenpropathrin act at different sites in susceptible insects. The combination does not imply guaranteed control of every pest stage or resistance problem.
-
Growth regulation: Pyriproxyfen, IRAC Group 7C, modulates juvenile-hormone receptors and disrupts normal insect development, including the development of immature whitefly stages.
-
Nerve action: Fenpropathrin, IRAC Group 3A, modulates sodium channels in the pest nervous system.
-
Targeted result: Use the combination for the crop and pest stated on the pack; do not treat its components as proof of unlisted crop or mite uses.
Different brands containing the same mode-of-action group are not distinct rotation partners. Follow label-compliant resistance-management guidance rather than repeated use of one group.
Consider both IRAC groups in resistance-management planning. Ingredient-level activity does not authorise an extra crop or pest use or establish treatment of a virus disease.
Target Crops & Pests
The following crop-target pairs are listed by Sumitomo Chemical India. They are not an all-crop recommendation; confirm the same use on the supplied label.

For okra and chilli, “bollworms” preserves the manufacturer’s wording. Confirm the exact named borer on the supplied label. Mites and thrips are not added to this guide.
Dosage & Application Guide
Application Requirements
Use one complete crop-specific programme from the supplied label: match the target pest, product quantity, spray-water volume, method, crop stage and harvest interval. Do not combine quantities or waiting periods from different formulations or programmes.
The pre-harvest interval (PHI) is the time between the final application and harvest. Follow the interval for the exact crop and target on the supplied label, together with its re-entry and repeat-treatment directions. Do not assume a zero-day interval or a universal per-litre recipe.
How to Apply: Best Practices
-
Match the pack: Check the brand, concentration and formulation, then verify the crop and pest.
-
Use one complete programme: Take product amount, water, timing, method and waiting periods from the same current label.
-
Obtain even coverage: Spray during cooler hours, using label-directed equipment and conditions. Avoid drift and do not improvise a different application route.
-
Observe restrictions: Follow protective measures, mixing restrictions, harvest and re-entry directions on the pack.
- Select the label-directed product quantity with local crop advice. Do not automatically choose the upper end of a stated range.
- EC means emulsifiable concentrate. Dilute and prepare it according to the supplied label; do not spray it neat or use tank capacity alone to determine the product quantity.
