Product details
Symatic Herbicide by Coromandel
A selective, post-emergence herbicide identified by the manufacturer for purple nutsedge (Cyperus rotundus). Confirm the current pack for approved crops and directions.
Composition: Halosulfuron methyl 75% WDG.
Target focus: Purple nutsedge, Cyperus rotundus; confirm the crop-specific pack approval.
Before treatment: Match the crop and target to the supplied label and check the complete application and harvest directions.
Why Choose This Product? Key Benefits
- 🌿Nutsedge focus: The manufacturer specifically identifies Cyperus rotundus rather than claiming control of every weed.
- ⏱️Post-emergence role: Intended for use after target weeds emerge, subject to the supplied label.
- 🌱Residual activity: The manufacturer describes residual action; no fixed duration of control is guaranteed here.
- 🟤Dispersible granules: The 75% WDG formulation disperses in water; do not confuse product weight with active-ingredient weight.
- 🔄Defined action group: HRAC Group 2 helps identify suitable rotation options rather than relying on brand names.

How It Works: Mode of Action
A selective, post-emergence herbicide identified by the manufacturer for purple nutsedge (Cyperus rotundus). Confirm the current pack for approved crops and directions.
- A growth enzyme is inhibited: Halosulfuron methyl inhibits ALS in susceptible weeds.
- Essential growth materials are reduced: This interrupts formation of certain amino acids that weeds need for growth.
- Growth is disrupted: Susceptible sedges stop normal development; correct weed identification and label-directed treatment remain essential.
Action groups help plan rotation. A different brand name does not necessarily mean a different mode of action. Follow crop-specific resistance-management directions.

*Formulation-reference quantities and waiting periods only, not confirmation of complete current Symatic label directions. These references do not establish current Symatic brand-label crop approvals. Confirm the exact crop, weed and full programme on the supplied pack.
No separate per-litre or tank dose is given. Obtain the application method, crop-stage timing, repeat interval, maximum applications, rainfast time and re-entry interval from the supplied label.
How to Apply: Best Practices
- Confirm the crop and target: Use the matching label entry, not a rate borrowed from another crop or a similar product.
- Follow the complete directions: Check the stated quantity, water volume, mixing sequence, equipment, application method and timing. The reference table is not a complete spray programme.
- Check mixtures and rotation: Do not assume compatibility with another pesticide, fertiliser or adjuvant. Follow label restrictions and rotate appropriately between action groups.
- Record treatment and harvest: Record the product, crop and date. Follow the applicable harvest waiting period and field-entry precautions on the supplied label.
