Active Ingredient Chemistry and Mode of Action
Fame belongs to the diamide chemical class and provides a distinct biochemical mode of action against lepidopteran larvae.
Key chemical characteristics:
- Active ingredient: Flubendiamide formulated as a suspension concentrate at 39.35% SC concentration.
- Ryanodine receptor modulator: Stimulates uncontrolled release of internal calcium ions in insect muscle cells, causing rapid feeding cessation, muscular paralysis, and death.
- Translaminar activity: Penetrates the leaf surface to control cryptic caterpillars feeding on the undersides of leaves or within plant tissues.
Approved Target Crops and Pest Complex
Flubendiamide is registered to control economic caterpillar infestations across major cash and food crops.
Primary registered applications:
- Vegetables (Tomato and Brinjal): Controls fruit borer (Helicoverpa armigera) and shoot and fruit borer (Leucinodes orbonalis).
- Cole crops (Cabbage and Cauliflower): Highly effective against diamondback moth (DBM) and tobacco caterpillar (Spodoptera litura).
- Rice: Controls yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis) during vegetative and boot stages.
- Cotton: Controls American bollworm and spotted bollworm, safeguarding flowering squares and developing bolls.
Spraying Guidelines and Resistance Management
Adhering to integrated pest management practices protects chemistry longevity and field effectiveness.
Recommended application rules:
- Early larval intervention: Spray during early instar stages before caterpillars bore deeply into fruits, bolls, or stems.
- Accurate dosage: Strictly measure according to official label directions using clean water for thorough canopy coverage.
- Resistance rotation: Rotate flubendiamide sprays with insecticides from alternative chemical classes (such as emamectin benzoate or spinosad).
- Pre-harvest interval: Observe mandatory pre-harvest waiting periods to ensure farm produce complies with national residue limits.

Common questions
What is the active ingredient in Fame insecticide?
Fame contains Flubendiamide 39.35% SC, a specialized diamide insecticide targeting lepidopteran caterpillar pests.
How does flubendiamide eliminate destructive borers?
It activates ryanodine receptors, releasing calcium in insect muscle cells and causing rapid muscle contraction, paralysis, and death.
Does Fame control sucking pests like aphids or whiteflies?
No, flubendiamide is highly specific to chewing caterpillar larvae (lepidoptera) and does not control sucking insects.
