Council Activ - Triafamone 20% + Ethoxysulfuron 10% WG - Bayer
Bayer Council Activ Rice Herbicide
Bayer Council Activ is a selective post-emergence rice herbicide containing Triafamone 20% + Ethoxysulfuron 10% WG. Both active ingredients inhibit acetolactate synthase and belong to HRAC/WSSA Group 2.
It is registered for listed grasses, sedges and broadleaf weeds in transplanted and direct-seeded rice; Bayer positions the latter use for wet DSR. The Government reference rate is 225 g/ha in 300 L water, with an 83-day PHI.
Important: Match the rice establishment system and weed list to the current Council Activ pack. Do not create a universal per-litre or acre dose, add a tank mix, or use an unverified drone direction.
Item description
Bayer Council Activ Rice Herbicide - Product Overview
Bayer Council Activ is a selective post-emergence rice herbicide containing Triafamone 20% + Ethoxysulfuron 10% WG. Bayer positions it for transplanted rice and wet direct-seeded rice, where the applicable label row covers listed grasses, sedges and broadleaf weeds.
Council Activ must be used only for the rice establishment system and weed spectrum printed on the current pack. Keep the formulation rate, spray-water volume, pre-harvest interval and all application conditions together. The current approved label takes priority if it differs from this page.

How Council Activ Works
Triafamone can enter susceptible weeds through roots and leaves, while Bayer describes Ethoxysulfuron as acting mainly through foliage. Both inhibit acetolactate synthase, an enzyme involved in branched-chain amino-acid biosynthesis. Because both actives are Group 2, this premix has one classified site of action and should not be described as a two-group resistance rotation.
Registered Rice Uses, Rate, Water & PHI
Use the row matching the establishment system. Do not combine the two weed lists or convert this table into one universal dose per litre, tank, pump or acre.
| Rice System | Registered Weeds | Formulation / ha | Water / ha | PHI |
|---|---|---|---|---|
| Transplanted rice | Echinochloa colona; E. crus-galli; Cyperus rotundus; C. difformis; Fimbristylis miliacea; Marsilea quadrifolia | 225 g | 300 L | 83 days |
| Direct-seeded rice (Bayer positioning: wet DSR) |
Echinochloa colona; Cyperus rotundus; Digera arvensis; Commelina benghalensis | 225 g | 300 L | 83 days |
PHI means pre-harvest interval after the last application. Follow the current Council Activ label for timing, weed stage, field-water condition, equipment, PPE and all restrictions.
Application & Resistance Care
- Identify the rice establishment system and target weeds before choosing the applicable row.
- Measure the treated area and use the hectare formulation and water quantities exactly as labelled.
- Do not create a universal g/L, tank, pump, sachet or unsourced acre dose.
- Do not add a tank mix, adjuvant, repeat interval or drone procedure unless the current Council Activ label expressly permits it.
- Use integrated weed-management practices, monitor escapes and prevent surviving weeds from setting seed.
- A different Group 2 herbicide is not a different-group resistance rotation. Check the alternative product's own current India label.
