| Formulation | TC |
| Application/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. 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. |
| ECOTOXICOLOGY | The high toxicity of cyhalofop-butyl to fish and other aquatics is mitigated by the rapid degradation to less-toxic metabolites. Birds Acute oral LD50 for bobwhite quail and mallard ducks >5620 mg/kg. Dietary LC50 for bobwhite quail and mallard ducks >2250 ppm. Fish LC50 for rainbow trout >0.49, bluegill sunfish 0.76 mg/l. These values are at or above the aqueous solubility of cyhalofop-butyl. Daphnia LC50 >100 mg/l. Algae EC50 for Selenastrum capricornutum >1, Navicula sp. 0.64-1.33 mg/l. Soil and plant transformation products are less toxic to Selenastrum capricornutum. Other aquatic spp. EC50 for eastern oyster (Crassostrea virginica) 0.52, scud (Gammarus sp.) 0.81 mg/l. These values are at or above the aqueous solubility of cyhalofop-butyl. Bees NOEC for honeybees >100 mg/bee. Worms LD50 (14 d) for earthworms >1000 mg/kg. |
