Versatile wettable powder formulation: Easy to apply as a dry seed treatment or mixed with water for foliar sprays and soil drenches.
Seed and seedling defence: Prevents seed decay, damping-off, and seedling blight, promoting stronger germination and better early crop establishment.
Post-harvest and storage support: Helps protect crops from spoilage during handling, storage, and transport.
