Tricyclozole 75%WP 

Active Ingredient:
Tricyclazole 75% Wettable Powder

Mode of Action:
BLAST OFF is Melanin biosynthesis inhibitor.

Systemic fungicide absorbed rapidly by the roots, with translocation through the plant.

Benefits:
BLAST OFF is used world wide as the most acceptable fungicide for Blast control

BLAST OFF is highly systemic in nature and is not removed by rain water. Rains may actually increase the rate of Blastin absorption.
