Solubility In water 1.9 (pH 5), 2.4 (pH 9), 1.9 (distilled) (all in mg/l, 20 °C). In acetone 545.9, dichloromethane 22.3, hexane 0.028, toluene 3.0 (all in g/l, 20°C).
Stability Stable in water at pH 5 and 7; slowly hydrolysed at pH 9 (DT50 c. 28 d). Stable to heat. Slowly degrades in sunlight (c. 3% loss after 12 d continuous irradiation); rapidly photolysed in aqueous solution (DT50 c. 0.33 d).
Mode of Action
Broad-spectrum insecticide, toxic by contact and ingestion. Moderately systemic and, in some crops, can be used to control insects when applied as a soil or seed treatment. Good to excellent residual control following foliar application.
Oral Acute oral LD50 for rats 97, mice 95 mg/kg.
Skin and eye Acute percutaneous LD50 for rats >2000, rabbits 354 mg/kg. Not a skin or eye irritant (OECD criteria). Not a skin sensitiser.
