Amistar Top Fungicide Features and Benefits
Dual Systemic Protection
Combines two highly effective systemic fungicides that move within plant tissues to protect new and existing growth.
Preventive + Curative Action
Prevents fungal infection before occurrence and cures early-stage infections after disease appearance.
Broad-Spectrum Control
Effective against Powdery Mildew, Downy Mildew, Anthracnose, Leaf Spots, Sheath Blight, and Fruit Rot.
Translaminar & Xylem Mobility
Azoxystrobin provides translaminar movement, while Difenoconazole moves systemically through plant vascular tissues, ensuring complete coverage.
Anti-Sporulant Activity
Stops spore formation, reducing disease spread in the field.
Resistance Management Tool
Combination of two different modes of action helps delay resistance development.
Long Residual Effect
Provides extended protection period, reducing the number of sprays.
Mode of Action Explained
Azoxystrobin (QoI Fungicide – FRAC Group 11)
Blocks mitochondrial respiration in fungal cells, preventing energy production and stopping fungal growth.
Difenoconazole (DMI Fungicide – FRAC Group 3)
Inhibits sterol biosynthesis required for fungal cell membrane development, effectively stopping fungal multiplication.
The combination ensures multi-stage fungal control — from spore germination to mycelial growth.
