Toxicity & Irritation
Rat LD50 oral: >5000 mg/kg bw
Rat LD50 dermal: >2000 mg/kg bw
Rat LC50 inhalation: >5.63 mg/l/4hr (dust; Whole body exposure)
Skin irritation: Non-irritant

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.
