ECOTOXICOLOGY

Effect on birds: Acute oral LD50 for Japanese quail is >5000 mg/kg. Effect on fish: Acute LC50 (96 h) for Rainbow trout is >170 mg/l. Effects on aquatic invertebrates: Acute EC50 (48 h) for Daphnia magna is >1.5 mg/l. Effects on algae: Acute 72 hour EC50 is 0.64 mg/l. Effects on bees: contact acute 48 hour LD50 is >10 μg/bee. Effects on earthworms: Acute 14 day LC50 is >542 mg/kg.   

ENVIRONMENTAL FATE

Animals In rats, following oral administration, 78.5% is eliminated in the urine and 20.1% in the faeces within 48 h. Plants In soya beans, the parent molecule is oxidised, structurally rearranged, and conjugated. Transformation to metabolites is very rapid. Soil/Environment DT50 in soil <1 d at 15. Metabolism involves molecular rearrangement, oxidation and conjugation processes.  

Usage: Sethoxydim was introduced by Nippon Soda Co., Ltd. It is a post-emergence, selective, annual and perennial grass weed herbicide.

Application: Biochemistry Fatty acid synthesis inhibitor, by inhibition of acetyl CoA carboxylase (ACCase). Inhibits mitosis. Mode of action Selective systemic herbicide, absorbed predominantly by the foliage, and, to a lesser extent, by the roots. Translocated rapidly both acropetally and basipetally. Uses Control of annual (at 0.20-0.25 kg/ha) and perennial (0.2-0.5 kg/ha) grasses (except Poa spp.) in broad-leaved crops, including cotton, oilseed rape, soya beans, sugar beet, fodder beet, sunflowers, spinach, potatoes, tobacco, peanuts, strawberries, alfalfa, flax, and vegetables.
