Ecotoxicology:
Bees:Dust is non-toxic topically to honeybees at 0.03 mg/bee.Birds:Acute oral LD50 for mallard ducks >2510, bobwhite quail 1828 mg/ kg.Daphnia: LC50 (48 h) 1.14 mg/l; little hazard would be expected under field conditions because of the very low solubility in water.Fish:Toxic under laboratory conditions using a solvent, but very little risk to fish is expected under normal field conditions because of the compound's low solubility in water and rapid degradation in sunshine.LC50 (96 h) for bluegill sunfish 1.70, rainbow trout 0.16, channel catfish 0.10 mg/l; for carp 0.67, 0.39, and 0.34 mg/l (24, 48, and 72 h, respectively).Daphnia LC50 (48 h) 1.14 mg/l; little hazard would be expected under field conditions because of the very low solubility in water.Bees Dust is non-toxic topically to honeybees at 0.03 mg/bee.
Environmental fate:
Animals:In rats, following oral administration, rapidly eliminated in the faeces and urine. No residues were detectable in the milk or tissues of goats (0.2 mg/ kg in the daily diet for 8 days). No residues were found in the milk Soil:Rapidly degraded in sunlight by photolysis ( DT50 <1 h). Half-life in sandy loam is c. 7 d; half-life when incorporated in sandy loam is c. 28 d. Formulated bait decomposes rapidly in daylight. Not mobile and doPlant:Residues in grass 4 months after treatment were <0.01 ppm. Negligible residues were found in radishes, barley, and french beans planted 3 months after treatment of the soil.
