Technical Specifications

  • Mode of Action

    •  Granite causes death of target weeds by inhibiting the plant enzyme Aceto Lactate Synthase (ALS).
    •  Inhibition of ALS stops synthesis of amino acids which affects protein synthesis and cell division ultimately leading to death of target weeds.
    •  Granite provides dual action to control target weeds: 
    •  Its application at 1-3 leaf stage which generally coincides with 8-12 days after transplanting, controls germinated weeds present in the field (1st action). 
    • Application at this stage also reduces fresh germination of weeds which was expected to come from subsequent flushes of weeds (2nd action).

Always read and follow label directions.
