Applications

Azimsulfuron is a selective, systemic herbicide belonging to the sulfonylurea class. It is primarily used in rice cultivation for controlling a wide range of weeds, including grasses, sedges, and broadleaf weeds. Below are its key applications:

1. Target Crops

• Rice (Paddy fields) - Both transplanted and direct-seeded rice.

• Occasionally used in other crops, depending on regional approvals.
   

2. Target Weeds

Azimsulfuron effectively controls:

• Grasses: Echinochloa crus-galli (Barnyard grass), Leptochloa chinensis (Chinese sprangletop).

• Sedges: Cyperus difformis (Smallflower umbrella sedge), Cyperus iria (Rice flatsedge).

• Broadleaf Weeds: Monochoria vaginalis (Monochoria), Lindernia spp. (False pimpernel), Ammannia spp. (Redstem).

3. Mode of Action

• Inhibits acetolactate synthase (ALS) or acetohydroxyacid synthase (AHAS), essential enzymes for branched-chain amino acid (valine, leucine, isoleucine) synthesis in plants.

• Leads to growth inhibition and eventual death of susceptible weeds.

4. Application Method

• Formulation: Wettable powder (WP) or granules.

• Application Timing: Early post-emergence (2-3 weeks after transplanting or weed emergence).

• Dosage: Typically 15-35 g a.i./ha (varies based on weed pressure and formulation).

• Spray Method: Foliar application with sufficient water (500-600 L/ha).

• Water Management: Fields should be moist but not flooded at application; flooding can be resumed after 2-3 days.

5. Advantages

• Selective activity: Safe for rice but toxic to weeds.

• Low application rate: Highly effective at low doses.

• Broad-spectrum control: Covers multiple weed types.

• Residual activity: Provides extended weed suppression.

6. Precautions

• Phytotoxicity Risk: Overdosing or improper application can harm rice.

• Resistance Management: Rotate with other herbicide modes of action to prevent weed resistance.

• Environmental Impact: Avoid runoff into water bodies to protect aquatic life.

7. Trade Names

• Gulliver, Sirius, Agil, Segment (varies by manufacturer).

Azimsulfuron is a valuable tool in integrated weed management (IWM) for rice farming, reducing labor costs and improving yields. Always follow local label recommendations for safe and effective use.
