Applications |
Mode of action 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. Uses 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, see M. Ito et al., J. Weed Sci. & Tech. 43(2) 122-128 (1998). Phytotoxicity Rice is completely tolerant to due to rapid metabolism to the inactive diacid. |
