Herbicide
ORYZALIN 15% + FLUROXYPYR-METHYL 2% + QUINCLORAC 9% OD
A selective Oil Dispersion (OD) herbicide that provides effective pre- and early post-emergence control of annual grasses, broadleaf weeds, and selected sedges in rice. The combination offers both residual and systemic activity for broad-spectrum, long-lasting weed control.
Active: Oryzalin + Fluroxypyr-methyl + Quinclorac
Formulation: OD (Oil Dispersion)
Selective Pre- & Early Post-Emergence
Triple HRAC Group 3 + 4 + 4 Action
Product Information
Mode of Action
Oryzalin (HRAC Group 3) inhibits microtubule assembly and cell division during seedling germination. Fluroxypyr-methyl (HRAC Group 4) is a synthetic auxin that interferes with normal plant cell development and systemic tissue function. Quinclorac (HRAC Group 4) mimics auxin activity, halting growth in susceptible grasses and broadleaf weeds. Together, this multi-site combination delivers complete residual and systemic suppression.
Target Weeds
- Echinochloa crus-galli (Barnyardgrass)
- Echinochloa colona (Jungle Rice)
- Leptochloa chinensis
- Monochoria vaginalis
- Ludwigia spp.
- Cyperus difformis
- Fimbristylis miliacea
- Annual grasses, broadleaf weeds, and selected sedges
Recommended Application Guidance
| Crop | Target Weeds | Dosage & Method of Application |
|---|---|---|
| Rice (Direct-Seeded & Transplanted) | Annual grasses, broadleaf weeds & selected sedges | Apply as a pre-emergence or early post-emergence spray at the recommended label dosage. Ensure uniform spray coverage and maintain adequate soil moisture or a shallow water layer for optimum weed control. |
For specific L/ha or ml/ha dosage rates and local field water management guidelines across direct-seeded and transplanted rice, please refer to the registered product label or consult local agricultural extension specialists.
Application Instructions
1. Pre- or Early Post-Emergence Spray Window
Apply as a pre-emergence soil treatment or early post-emergence foliar spray when targeted annual grasses, broadleaf weeds, and sedges are in early germination and seedling stages for maximum uptake.
2. Water Management & Uniform Spray Coverage
Ensure uniform spray coverage across the paddy field using calibrated spraying equipment. Maintain optimal soil surface moisture or a shallow water layer (3–5 cm) to activate the residual soil barrier.
Safety & Environmental Care
Always wear appropriate personal protective equipment (gloves, goggles, face mask, protective suit) during handling, mixing, and application. Avoid spray drift onto non-target crops and nearby aquatic habitats. Store in original sealed container in a cool, dry, well-ventilated location away from food, drink, and animal feed.
