Chemical classification, mode of action, and pest spectrum
Tetraniliprole operates via a modern chemical pathway (IRAC Group 28), providing robust control against challenging insect larvae.
- Ryanodine receptor modulation: Uncontrolled release of intracellular calcium ions paralyzes pest muscle tissue, halting crop feeding within hours.
- Soybean pest protection: Controls destructive defoliators and borers including girdle beetle (Obereopsis brevis) and tobacco caterpillar (Spodoptera litura).
- Rice and maize defense: Manages rice yellow stem borer, leaf folder, and highly damaging fall armyworm (Spodoptera frugiperda) infestations in maize.
- Ovi-larvicidal activity: Impacts insect eggs and emerging larval stages, preventing initial establishment and crop defoliation.
Translaminar properties, rainfastness, and spraying guidelines
Vayego exhibits translaminar movement, diffusing through leaf surfaces to protect both upper and lower foliar planes.
- Rapid rainfastness: Penetrates the plant cuticle quickly, maintaining high insecticidal efficacy even if rain showers occur shortly after application.
- Scouting and timing: Spray upon reaching economic threshold levels (ETL) or at the first appearance of young caterpillar instars.
- Water volume and coverage: Use clean water with calibrated knapsack or motorized power sprayers fitted with hollow cone nozzles for thorough canopy penetration.
- Integrated Pest Management (IPM): Demonstrates a favourable ecotoxicological profile, preserving beneficial predatory insects and spiders when used according to instructions.
Application safety, protective gear, and resistance management
Follow the official dosage rates and safety directions registered by the Central Insecticide Board and Registration Committee (CIBRC). Applicators must use personal protective equipment, avoid direct skin contact or inhalation, and refrain from eating or smoking while spraying. Practice insecticide resistance management by rotating Vayego with non-diamide insecticides featuring alternative modes of action.

Common questions
What active chemical ingredient is contained in Bayer Vayego?
Vayego contains Tetraniliprole 200 SC (18.18% w/w), an anthranilic diamide insecticide.
Which major crop pests are managed by Vayego insecticide?
It controls chewing insect pests including soybean girdle beetle, Spodoptera litura, rice stem borer, leaf folder, and maize fall armyworm.
How does Vayego stop insect feeding so quickly?
It activates insect ryanodine receptors, exhausting calcium stores and causing immediate muscle paralysis that stops insect feeding within hours.
