Dual Active Chemistry and Granular Soil Systemic Action
Virtako combines an anthranilic diamide (Chlorantraniliprole) with a systemic neonicotinoid (Thiamethoxam) in dry broadcast granules.
Chlorantraniliprole acts on insect ryanodine receptors to paralyze muscles and halt caterpillar feeding within minutes, while Thiamethoxam translocates systemically to control sap-sucking pests.
When broadcast into moist soil, the active chemicals dissolve and are absorbed by plant roots, translocating acropetally to protect expanding tillers from within.
- Formulation: Chlorantraniliprole 0.5% + Thiamethoxam 1.0% GR
- Root systemic uptake: Translocates acropetally through plant xylem to protect tillers and leaf sheaths
- Long residual control: Provides several weeks of continuous protection against boring larvae
Target Pests and Approved Crop Applications
Virtako is registered for soil application in transplanted rice and sugarcane during early vegetative growth stages.
Broadcasting granules provides continuous protection against boring caterpillars, eliminating the need for frequent foliar spray passes.
- Paddy: Controls yellow stem borer (dead hearts and white ears) and leaf folder
- Sugarcane: Suppresses early shoot borer and top borer during formative tillering phases
- Crop vigor: Promotes healthy root establishment, vigorous tillering, and uniform plant stands
Application Instructions, Moisture, and Safety
Broadcast granules evenly across the field when soil contains adequate moisture or standing water.
In paddy fields, maintain shallow standing water (two to three inches) for several days post-application to ensure granule dissolution and root uptake.
Wear protective rubber boots and gloves during broadcasting.
- Water management: Maintain shallow standing water in paddy basins for 3 to 4 days after broadcasting
- Uniform broadcasting: Mix with dry sand or fertilizer for even field distribution
- Personal protection: Wear protective rubber gloves, mask, and boots during handling

Common questions
What chemicals are in Syngenta Virtako?
Virtako contains Chlorantraniliprole 0.5% + Thiamethoxam 1.0% GR in a granular soil formulation.
How does Virtako protect paddy crops from stem borer?
The granules dissolve in standing water, and the active chemicals are absorbed by roots and translocated to tillers, poisoning borers as they feed inside.
When should Virtako be applied in transplanted rice?
Apply Virtako fifteen to twenty-five days after transplanting when rice plants are actively establishing tillers.
