Chemical Class and Novel Isoxazoline Chemistry
Fluxametamide 10% EC represents the isoxazoline class of insecticidal chemistry. It features a distinct mode of action that targets gamma-aminobutyric acid (GABA)-gated chloride channels in the insect nervous system.
Unlike legacy GABA disruptors (such as fipronil) that target the channel pore, Fluxametamide binds to a distinct allosteric site. This difference means it encounters zero cross-resistance from existing pest populations resistant to organophosphates, pyrethroids, or neonicotinoids.
- Active ingredient: Fluxametamide 10 percent w/w EC
- Insecticide group: IRAC Group 30 (GABA-gated chloride channel allosteric modulators)
- Mode of action: Contact and ingestion with strong translaminar penetration
- Resistance advantage: No cross-resistance with conventional insecticides
CIBRC Approved Target Crops and Pests
The Central Insecticides Board registers Fluxametamide for difficult-to-control chewing, scraping, and boring pests across high-value vegetable crops.
The compound penetrates leaf cuticles via translaminar action, reaching pests that feed on leaf undersides, in closed apical shoots, or inside tight floral buds.
- Chilli: Chilli thrips (*Scirtothrips dorsalis*) and fruit borer (*Helicoverpa armigera*)
- Brinjal: Shoot and fruit borer (*Leucinodes orbonalis*) and thrips
- Cabbage and Cauliflower: Diamondback moth (DBM - *Plutella xylostella*)
- Tomato: Leaf miners and fruit borers
Application Guidelines and Resistance Stewardship
For maximum efficacy, apply Fluxametamide at early pest emergence before larval instars bore deeply into fruits or buds. Calibrated sprayers with hollow cone nozzles ensure thorough leaf coverage.
To safeguard this modern chemistry against resistance, avoid exceeding recommended seasonal applications and rotate with other chemical classes like diamides or spinosyns.
- Spraying window: Apply at economic threshold levels on young larval instars and active thrips
- Water volume: Calibrate 500 liters per hectare for knapsack spray equipment
- Stewardship: Limit to 2 applications per cropping cycle to maintain field susceptibility
- Applicator safety: Wear gloves, protective eyewear, and coveralls during preparation

Common questions
What makes Fluxametamide effective against resistant thrips?
Fluxametamide binds to a novel allosteric site on GABA-gated chloride channels (IRAC Group 30), overcoming target-site resistance built up against neonicotinoids and pyrethroids.
Does Fluxametamide have translaminar activity?
Yes, it penetrates through the leaf cuticle to reach pests feeding on the underside of foliage, such as thrips, leaf miners, and young caterpillars.
Is Fluxametamide effective against Diamondback Moth (DBM)?
Yes, it is registered for controlling diamondback moth larvae in crucifers, delivering high knockdown and extended residual protection.
