How It Works: A Dual-Attack Mode of Action
Vostrix's "Power of 3" formulation attacks weeds from two different biological pathways at the same time:
- Stops Fat Production (Grasses): The Metamifop (Group 1) ingredient blocks the ACCase enzyme, which stops grassy weeds from producing the fats they need to build new cells.
- Stops Protein Synthesis (Broadleaves): The Imazethapyr & Imazamox (Group 2) ingredients block the ALS enzyme, starving broadleaf weeds and sedges of the essential amino acids needed for growth.
- Synergistic Attack: This patented 3-way combo overwhelms the weed's defenses, ensures high effectiveness, and is a powerful tool for managing herbicide resistance.
This multi-site attack means Vostrix controls the entire weed flora, from tough grasses to stubborn broadleaves.

Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (ml / Acre) | Water (L / Acre) | Dose (ml / Litre) | PHI (Days) |
|---|---|---|---|---|
| Soybean | 400 ml | 200 L | 2.0 ml | 56 Days |
| Groundnut | 400 ml | 200 L | 2.0 ml | 83 Days |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Apply as a post-emergence spray when weeds are young and actively growing (typically at the 2-4 leaf stage) for best results.
- Mixing: Crucial: Always mix with the recommended adjuvant. Fill the tank with half the water, add Ammonium Sulphate (@ 250 gm/acre) and dissolve it completely. Then, add Vostrix (400 ml/acre) and the remaining water.
- Coverage: Use a knapsack sprayer with a flat fan or flood jet nozzle. Ensure thorough and uniform coverage of all weed foliage.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
