Introduction
Fast-1 is a powerful combination herbicide from Panchkhal Beej Bhandar formulated with Atrazine 50% and Mesotrione 5% SC. These two complementary active ingredients together control an exceptionally wide range of both broadleaf and grassy weeds in maize and sugarcane — the most economically important crops of Nepal's Terai region. Its dual mechanism reduces the risk of weed resistance and delivers cleaner fields for a full cropping season.
How It Works
Atrazine inhibits photosynthesis in susceptible plants by blocking electron transport in photosystem II, effectively starving weeds of energy. Mesotrione inhibits the enzyme p-hydroxyphenylpyruvate dioxygenase (HPPD), disrupting carotenoid biosynthesis which causes the weed to bleach and die. Together they attack two separate biological pathways in weed plants.
Key Benefits
- Dual-action formula controls both broadleaf and grassy weeds effectively
- Two different modes of action significantly reduce the risk of weed resistance
- Effective pre- and early post-emergence — flexible application timing
- Long residual soil activity keeps fields weed-free for extended periods
- Ideal for maize and sugarcane systems in Nepal's Terai and mid-hill regions
