Uses:

Post-emergence herbicide with foliar uptake only and no soil activity. A systemic herbicide that is readily absorbed by plant tissue is moderately phloem-mobile and accumulates in meristematic regions. Grass weeds cease growth immediately after treatment, with yellow patches appearing within 2-3 days to one week, leading to necrosis and death of the whole plant within 2 to 3 weeks. For post-emergence control of grass weeds in rice. Applied at 75-100 g/ha in tropical rice and 180-310 g/ha in temperate rice. For selectivity in Poaceae species.

  Applications

Cyhalofop-butyl is a selective systemic post-emergent herbicide with foliar uptake only and no soil activity. It is the safest herbicide for the control of grass weeds in rice field and it will not be phytotoxic to rice in all cultivation forms from seedling to jointing stage. Cyhalofop-butyl is highly effective in controlling cockspur grass, chinese sprangletop and it can also control crab grass, green bristlegrass, goosegrass, etc.
