Active ingredient: Oxadiargyl 80% WP



  • Works at the time of weed emergence as contact herbicide.
  • When uniformly spread, sticks evenly to soil surface.
  • It is selective to rice plant.
  • It firmly binds soil particles within top 2 cm of the soil.
  • No damage to the next crop.
  • No odour which helps in easy usage.
  • Safety to Crop: No phytotoxicity at the recommended dose rates in transplanted rice.


Mode of Action:

Like any other Oxadiazoles, Oxadiargyl inhibits protoposphyrinogen IX oxidase, the enzyme that converts from Protox to Proto, which finally helps in the weed's necrotic action.
