Item description
HPM Freedom Mix Metsulfuron Methyl 10% + Chlorimuron Ethyl 10% WP Rice Herbicide
Freedom Mix is a selective systemic rice herbicide combining two sulfonylurea ALS/AHAS inhibitors. It is registered at very low dose for listed sedges and broadleaf weeds in transplanted and puddled direct-sown rice.
Use note: The current regulatory dose is 20 g/ha (about 8 g/acre) in 300 L water/ha with a 90-day PHI. Follow the current pack instead of the broader 8–12 g/acre website range.
Key Product Benefits
- Low-dose control of labelled sedges and broadleaf weeds.
- Root and foliar uptake for pre- or post-emergence use at the correct rice stage.
- Registered use in transplanted and puddled direct-sown rice.
Technical Specifications
| Parameter | Details |
|---|---|
| Manufacturer | HPM Chemicals and Fertilizers Limited |
| Active ingredients | Metsulfuron Methyl 10% + Chlorimuron Ethyl 10% WP |
| Type | Selective systemic rice herbicide |
| Mode of action | Both actives are HRAC Group 2 ALS/AHAS inhibitors |
| Dose | 20 g/ha, about 8 g/acre |
| Water | 300 L/ha |
| PHI | 90 days |
Mode of Action
Both active ingredients inhibit ALS/AHAS and belong to HRAC Group 2. Because the mixture does not provide two different resistance groups, rotate future rice programmes with a different effective HRAC group and integrate non-chemical control.
