Introduction
Fast-2 is a selective triazine herbicide containing Atrazine 50% SC — one of the most widely used and reliable herbicides in maize farming worldwide. It provides both pre- and post-emergence control of annual grasses and broadleaf weeds. With decades of proven performance and very competitive pricing, Fast-2 is the trusted choice for maize and sorghum growers across Nepal.
How It Works
Atrazine blocks photosynthetic electron transport by binding to the D1 protein of photosystem II in susceptible weed species. The weed is unable to convert sunlight into energy and dies within days of exposure. Maize and sorghum possess enzyme systems that rapidly metabolise and deactivate Atrazine, which explains its selectivity.
Key Benefits

- Residual soil activity provides protection for 4–6 weeks after application
- Very economical — one of the lowest-cost weed control options for maize
- Decades of proven reliability in maize systems across Nepal and globally
- Compatible with many other herbicides for tank-mix broadening of weed spectrum
