Introduction
Crop Clean is a selective post-emergence herbicide containing Simetryn 25% WP, specifically developed for weed control in transplanted and direct-seeded rice. It controls annual grasses and many broadleaf weeds that compete with rice in the critical early growth stage — when weed competition most severely impacts yield.
How It Works
Simetryn belongs to the triazine class and inhibits photosynthesis by blocking electron transport in photosystem II of susceptible weed species. It is selectively absorbed by weeds while rice plants metabolise and deactivate it rapidly, making it safe for the crop at recommended rates.
Key Benefits
- Selective — effective on weeds while safe for transplanted and direct-seeded rice
- Controls both annual grasses and broadleaf weeds in one application
- Reduces early-season weed competition that causes most yield loss in rice
- WP formulation — easy to measure and mix with water
- Cost-effective solution for paddy farmers across Nepal's Terai and mid-hills
