Chemical profile and ryanodine receptor mode of action
- Active ingredient: Flubendiamide 20% WG (water dispersible granules, IRAC Group 28).
- Mode of action: Activates ryanodine receptors in insect muscle cells, causing massive internal calcium release and irreversible muscle contraction.
- Cessation of feeding: Target larvae stop feeding on foliage within minutes of ingestion, preventing economic crop damage.
- Rainfastness: Rapidly penetrates leaf cuticles within two hours of application, offering outstanding resistance to monsoon wash-off.
Target insect pests and registered crop portfolio
- Paddy (Rice): Controls yellow stem borer (Scirpophaga incertulas) and rice leaf folder (Cnaphalocrocis medinalis).
- Cotton: Highly effective against American bollworm (Helicoverpa armigera) and spotted bollworm.
- Pulses (Pigeon pea, Chickpea): Controls pod borer complex (Helicoverpa and Maruca vitrata).
- Vegetables: Manages diamondback moth (DBM) in cabbage and cauliflower, and fruit and shoot borer in tomato and brinjal.
- Safety profile: Demonstrates high safety toward beneficial predatory insects, pollinators, and adult parasitoids.
Spraying protocol, equipment, and stewardship
- Application timing: Spray at the early instar caterpillar stage or upon observing egg hatch and initial leaf scraping.
- Water volume: Ensure thorough foliar coverage using 150 to 200 litres of clean water per acre with a hollow cone nozzle.
- Resistance management: Rotate applications with other insecticide modes of action such as spinosad or emamectin benzoate.
- Waiting period: Observe the pre-harvest interval (PHI) stipulated on the CIB&RC approved product label.

Common questions
What is the active chemical in Tata Takumi?
Tata Takumi contains Flubendiamide 20% WG, a diamide insecticide targeting caterpillar pests.
Which pests does Tata Takumi control?
It controls lepidopteran caterpillar pests including rice stem borer, leaf folder, cotton bollworms, and pod borers.
How does Flubendiamide work inside insect larvae?
It activates ryanodine receptors, triggering uncontrolled calcium release that paralyzes the insect muscles and stops feeding.
Is Tata Takumi safe for beneficial insects?
Yes, it has a favorable ecotoxicological profile and is relatively safe for predatory mites, spiders, and honeybees when used as directed.
