Council Active Herbicide: Active Molecules and Weed Management

Dual Chemistry and Target Weed Spectrum

Council Active combines Triafamone (a triazolopyrimidine sulfonamide ALS inhibitor) with Ethoxysulfuron (a sulfonylurea ALS inhibitor). This dual-action formulation inhibits acetolactate synthase, halting branched-chain amino acid synthesis across diverse paddy weed families.

The combination prevents competitive weed pressure during the critical vegetative tillering window of rice.

• Grassy weeds: Echinochloa crus-galli (barnyard grass) and Echinochloa colona (jungle rice).
• Sedges: Cyperus difformis, Cyperus iria, and Fimbristylis miliacea.
• Broadleaf weeds: Ludwigia parviflora, Sphenoclea zeylanica, and Eclipta alba.
• Broad application window: Effective at early post-emergence stage when weeds are at the 2 to 4 leaf stage.

Water Management and Field Application

Proper water depth at the time of herbicide application is decisive for efficacy. Fields should be drained to expose weed foliage prior to spraying, followed by re-flooding 24 to 48 hours later.

Failing to manage field standing water correctly can diminish the residual barrier that suppresses late weed flushes.

• Ensure a thin film of soil moisture is present during application; avoid spraying under drought stress.
• Re-establish a 3 to 5 cm water layer within 48 hours of spraying and maintain it for 5 to 7 days to prevent secondary weed emergence.
• Utilize flat fan nozzles with appropriate spray shields to ensure uniform swath distribution.
