Product Specifications

Key Benefits of Contras Plus +

• Systemic Protection: Hexaconazole is absorbed by treated plant tissues and helps suppress susceptible fungal infections.
• Preventive and Curative Action: Provides protective and early curative activity against susceptible fungal pathogens.
• Powdery Mildew Management: Recommended by the manufacturer for powdery mildew in grapes and mango.
• Rice Sheath Blight Management: Helps manage sheath blight in paddy.
• Silica Added Formulation: Contains added silica as described by the manufacturer.
• Uniform Distribution: The manufacturer describes the formulation as distributing uniformly on leaves and being rapidly absorbed.

How Does Contras Plus + Work?

Hexaconazole belongs to FRAC Group 3, a class of demethylation inhibitor fungicides. It inhibits sterol 14-alpha-demethylase, an enzyme involved in ergosterol production.

Ergosterol is important for normal fungal cell membrane development. By interfering with its synthesis, Hexaconazole restricts the growth of susceptible fungal pathogens.

Contras Plus + provides systemic protective and early curative action. The manufacturer identifies added silica in the formulation but does not separately quantify its concentration or establish a specific disease-control contribution.
