Introduction of Bayer Council® Activ Herbicide

Weed pressure is one of the biggest challenges in achieving high crop yields, especially in Paddy and other cereal crops. To help farmers tackle a wide spectrum of weeds effectively, Bayer offers Council® Activ Herbicide, a modern and powerful solution for reliable weed control. This herbicide is known for its strong action on grasses, broadleaf weeds, and sedges, ensuring cleaner fields and healthier crop growth.

If you are planning to use Bayer Council Activ for your crop, this detailed guide will help you understand its technical name, dose, dose per litre, dose per acre, benefits, and how to use it correctly.

Bayer Council Activ Herbicide – Technical Name

Bayer Council® Activ contains the following technical ingredients:

• Thiencarbazone-methyl (10%)
  
• Iodosulfuron-methyl-sodium (20%)
  

This combination makes it a broad-spectrum, selective, and systemic herbicide, highly effective for post-emergence weed control. It targets weeds by inhibiting essential amino acid synthesis, stopping their growth immediately and leading to complete weed death.

Council Activ Herbicide Formulation & Content

• Formulation Type: Water-dispersible granules (WDG)
  
• Mode of Action: Systemic, absorbed mainly through leaves and roots
  
• Target Weeds:
  
  • Grassy weeds: Echinochloa spp. (Barnyard grass), Panicum spp., Leptochloa spp.
    
  • Broadleaf weeds: Ammania spp., Eclipta alba, Ludwigia spp.
    
  • Sedges: Cyperus difformis, Cyperus iria
    

The balanced combination of Thiencarbazone and Iodosulfuron ensures quick absorption, faster weed drying, and longer-lasting control.
