Herbicide
OXAZICLOMEFONE 2% + CYHALOFOP-BUTYL 20% EC
A selective herbicide developed for effective post-emergence control of annual grassy weeds in rice. The combination provides rapid weed control, prolonged residual activity, and promotes healthy crop growth and higher productivity.
Active: Oxaziclomefone + Cyhalofop-butyl
Formulation: EC (Emulsifiable Concentrate)
Selective Post-Emergence
Dual HRAC Group 13 + 1 Action
Product Information
Mode of Action
Oxaziclomefone (HRAC Group 13) inhibits seedling development and early weed growth, preventing cell division and shoot establishment. Cyhalofop-butyl (HRAC Group 1) inhibits the Acetyl-CoA Carboxylase (ACCase) enzyme, blocking fatty acid synthesis in grassy weeds. Their combined action delivers rapid knockdown, extended residual activity, and long-lasting weed control in rice.
Target Weeds
- Echinochloa crus-galli (Barnyardgrass)
- Echinochloa colona (Jungle Rice)
- Leptochloa chinensis
- Ischaemum rugosum
- Annual and mixed grassy weeds
Recommended Application Guidance
| Recommended Crops | Target Weeds | Dosage & Method of Application |
|---|---|---|
| Rice | Annual grassy weeds | Apply as an early post-emergence spray as per the recommended label dosage with uniform spray coverage. |
| Rice | Mixed grassy weeds | Apply when weeds are at the 2–4 leaf stage for optimum weed control. |
For specific ml/ha dosage rates and local water carrier recommendations in transplanted and direct-seeded rice, please refer to the registered product label or consult local agricultural extension specialists.
Application Instructions
1. Early Post-Emergence Timing (2–4 Leaf Stage)
Apply as an early post-emergence foliar spray when target grassy weeds are actively growing in the 2–4 leaf stage to ensure maximum herbicide absorption and effective weed knockdown.
2. Uniform Coverage & Water Management
Ensure uniform spray coverage across the paddy using calibrated spraying equipment. Follow recommended field water management practices before and after application to optimize chemical activity.
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 water bodies. Store in original sealed container in a cool, dry, well-ventilated location away from food, drink, and animal feed.
