Product Specifications

Key Features and Benefits

• Dual Fungicidal Action: Combines Azoxystrobin and Tricyclazole for complementary disease management.
• Rice Blast Management: Helps protect paddy against susceptible blast infections.
• Sheath Blight Control: Supports management of sheath blight in rice.
• Brown Spot Management: Recommended for brown spot disease in paddy.
• Systemic Activity: Provides fungicidal activity within treated plant tissues.

Mode of Action

Azoxystrobin: Belongs to FRAC Group 11. It inhibits mitochondrial respiration in susceptible fungi, disrupting energy production and restricting fungal development.

Tricyclazole: Belongs to FRAC Group 16.1. It inhibits melanin biosynthesis, interfering with the ability of the rice blast fungus to penetrate plant tissues.

The combination provides complementary modes of action for managing susceptible rice fungal diseases.
