Welcome to discover our high-quality Cyhalofop-Butyl 10% EC, a powerful post-emergence herbicide designed specifically for rice field weed control. This advanced systemic herbicide offers superior grass weed management with excellent selectivity. Our formulation provides reliable performance in both direct seeding and transplanting rice fields. You can trust this professional-grade solution to deliver consistent results against resistant weed populations.
Our post-emergence herbicide features foliar uptake technology with no soil activity. This systemic formulation is readily absorbed by plant tissue and shows moderate phloem mobility. The active ingredient accumulates in meristematic regions of target weeds.
Grass weeds stop growing immediately after application. Yellow patches become visible within 2-3 days to one week after treatment. Complete necrosis and plant death occur within 2-3 weeks, ensuring thorough weed elimination.
This herbicide works effectively in direct seeding rice fields and transplanting rice systems. You can use it to control most malignant grass weeds including barnyard grass. The product successfully manages weeds that show resistance to dichloroquinolanic acid, sulfonylurea, and amide herbicides.
Rice farmers worldwide rely on this solution for challenging weed management situations. The selective action protects your rice crop while eliminating competitive grass species.
