Topstar Herbicide – Pre-Emergent for Early Weed Control in Paddy Fields

Technical Content: Oxadiargyl 80% WP

Features:

• 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.

Crops and Target Weeds:

Topstar should be applied within 3 to 5 days after transplanting (maximum up to 2 leaf stage of weed).
