Ryanodine Receptor Chemistry and Pest Control
Flubendiamide belongs to the ryanodine receptor modulator class (IRAC Group 28). It binds selectively to ryanodine receptors in insect muscle tissues, causing massive intracellular calcium release that results in rapid feeding cessation, muscular contraction, and larval death.
Its high specificity provides outstanding control over chewing caterpillars while remaining gentle on beneficial predatory insects and pollinators.
- Paddy: Yellow stem borer (Scirpophaga incertulas) and leaf folder (Cnaphalocrocis medinalis).
- Cotton: American bollworm (Helicoverpa armigera) and spotted bollworm.
- Pulses and vegetables: Gram pod borer in pigeonpea and chickpea; fruit borer in tomato and chilli.
- Rainfast formulation: Granules dissolve rapidly in water and adhere firmly to leaves, offering excellent resistance against monsoon rain wash-off.
Application Guidelines and Resistance Stewardship
Applying Takumi when insect scouting reveals early egg hatching or young larvae ensures maximum crop protection before caterpillars tunnel into plant stems.
Practicing mode-of-action rotation ensures that local caterpillar populations remain susceptible over successive growing cycles.
- Calibrate spray equipment to ensure thorough wetting of foliage and central crop whorls.
- Rotate with non-diamide insecticides to prevent target pests from developing resistance.
- Wear protective gloves, apron, and dust mask during measuring, dilution, and knapsack spraying.

Common questions
What is the active ingredient in Takumi insecticide?
Takumi contains Flubendiamide 20% WG, a selective ryanodine receptor modulator targeting lepidopteran larvae.
How does Takumi stop caterpillar feeding damage?
It disrupts internal calcium balance in insect muscles, paralyzing larvae and halting their feeding within minutes to hours.
Is Takumi effective against yellow stem borer in paddy?
Yes, Takumi provides systemic and translaminar activity that controls stem borer larvae before they produce dead hearts or white ears.
