Active ingredient and neurotoxic mode of action
Fipronil is a GABA-gated chloride channel antagonist classified under IRAC Group 2B. By binding specifically to the gamma-aminobutyric acid (GABA) receptor complex in insect central nervous systems, it blocks chloride ion influx. This triggers excessive neuronal excitation, convulsions, paralysis, and pest mortality.
- Active constituent: Fipronil 80% WG (water dispersible granules)
- Chemical group: Phenylpyrazole (IRAC Group 2B)
- Plant growth enhancement: Exhibits a proven phytotonic effect, promoting root branching, tillering, and dark green canopy vigor
Target crops and major pest complexes
- Paddy (rice): Yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis).
- Grapes: Scirtothrips dorsalis (grapevine thrips).
- Chili and onion: Thrips causing leaf curling and vectoring tospoviruses.
Application timing and safety precautions
Dissolve the low-dose water dispersible granules thoroughly in clean water and apply at the early onset of stem borer moths or leaf folder caterpillars. Wear protective chemical-resistant gloves and masks. Strictly comply with CIBRC registered label dosages and mandatory pre-harvest intervals.
