TOPSTAR HERBICIDE ( टॉपस्टार शाकनाशी )
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.
