Active chemical class and ryanodine receptor modulation
Vayego contains Tetraniliprole, an innovative active ingredient belonging to the anthranilic diamide chemical class (IRAC Group 28).
It works by binding selectively to ryanodine receptors in insect muscle cells, stimulating an unregulated release of internal calcium stores. This triggers muscle contraction, rapid feeding cessation, muscular paralysis, and death within 24 to 72 hours.
- Active chemical: Tetraniliprole 200 g/L SC (18.18% w/w).
- IRAC group: Group 28 (Ryanodine receptor modulator).
- Rapid feeding cessation: Target pests stop damaging leaves and fruiting parts within minutes of exposure, minimizing economic crop damage.
Target crops and approved pest spectrum
Vayego is registered for broad-spectrum caterpillar and beetle management across high-value horticultural and field crops.
It provides multi-stage pest efficacy, controlling insect eggs (ovicidal effect), developing larvae, and feeding adults.
- Chilli: Fruit borer (Helicoverpa armigera) and tobacco caterpillar (Spodoptera litura).
- Tomato: Fruit borer and leaf miner complexes.
- Cabbage: Diamondback moth (Plutella xylostella) and cluster caterpillar.
- Soybean: Semilooper and Spodoptera foliage feeders.
- Maize: Fall armyworm (Spodoptera frugiperda) during vegetative growth.
Application timing, dilution, and safety directions
Apply Vayego at the early onset of pest infestation or during peak moth flight and egg-laying windows for maximum protective longevity.
The suspension concentrate formulation mixes easily in clean water and provides good rainfastness once dried on crop canopies.
- Spraying practice: Ensure uniform foliar coverage using hollow cone nozzles operated at container label recommended dilution rates.
- Residual persistence: Provides long-lasting protection, reducing the required frequency of seasonal chemical applications.
- Worker safety: Wear chemical-resistant gloves, face mask, and eye protection; observe mandatory pre-harvest intervals.
