Active: Oxadiargyl + Pretilachlor + Pyrazosulfuron-ethyl
Formulation: OD (Oil Dispersion)
Selective Pre- & Early Post-Emergence
Triple HRAC Group 14 + 15 + 2 Action
Product Information
Mode of Action
Oxadiargyl (HRAC Group 14) inhibits protoporphyrinogen oxidase (PPO), causing cell desiccation and necrosis in broadleaf weeds. Pretilachlor (HRAC Group 15) inhibits very-long-chain fatty acid (VLCFA) synthesis, halting seedling emergence. Pyrazosulfuron-ethyl (HRAC Group 2) inhibits acetolactate synthase (ALS) enzyme activity, stopping amino acid synthesis and weed growth. Their combined action delivers long-lasting residual control and resistance management.

For specific ml/ha or L/ha dosage rates and local spray volume recommendations, please refer to the registered product label or consult local agricultural extension specialists.
Application Instructions
1. Pre- or Early Post-Emergence Timing
Apply as a pre-emergence or early post-emergence spray when weeds are in their initial growth stages to ensure rapid uptake and maximum residual activity.
2. Uniform Coverage & Water Management
Ensure uniform soil and foliar coverage using calibrated spray equipment. Maintain recommended field water management practices in paddy fields before and after application to optimize product efficacy.
Safety & Environmental Care
Always wear appropriate personal protective equipment (gloves, goggles, face mask, protective suit) during handling, mixing, and application. Avoid spray drift or chemical runoff into non-target crops and nearby water bodies. Store in original sealed container in a cool, dry, well-ventilated location away from food, drink, and animal feed.
