Environmental Profile

Ecotoxicology:
Bees: LD₅₀ (contact) >100 μg/bee.Birds:Acute oral LD₅₀ for bobwhite quail >3160 mg/kg. Dietary LC₅₀ (8 d) for mallard ducks and bobwhite quail >5000 mg a.i./ kg.Daphnia: LC₅₀ (48 h) 30 mg/l.Fish: LC₅₀ (96 h) for bluegill sunfish 1.6, trout 23 mg/l.

Environmental fate:
Animals:Hydrolysis of the ester and reduction of the nitro group.Soil:In soil and water, fluoroglycofen-ethyl is very rapidly hydrolysed to the corresponding acid.
SOIL PARTICLE ADSORPTION: Low potential to leach DEGRADATION/METABOLISM: Soil photolysis half-life 14 days; aqueous photolysis half-life 3-6 hr
