Useful:

• Chemical Classes: Pesticides -> Organophosphate Insecticides
• Canonical SMILES: COP(=O)(OC)OC(C(Cl)(Cl)Br)Br
• Inhalation Risk: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20 °C; on spraying or dispersing, however, much faster.
• Effects of Short Term Exposure: The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the nervous system. This may result in convulsions and respiratory depression. Cholinesterase inhibition. Exposure far above the OEL could cause death. The effects may be delayed. Medical observation is indicated.
• Effects of Long Term Exposure: Cholinesterase inhibition. Cumulative effects are possible. See Acute Hazards/Symptoms.
• Description: Sensitization to Naled seems to be rare. Naled is an organophosphate insecticide and acaricide that inhibits acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). It reduces the number of A. sollicitans mosquitos by 97% after one hour when aerially applied at a concentration of 0.1 pounds per acre. Naled (125 ppm AI) induces 100 and 64% mortality of T. telarius adults and immature mites, respectively, in an immediate contact toxicity test but does not induce mortality in mite eggs. It is toxic to rats with an LD50 value of 250 mg/kg. Formulations containing naled have been used in the control of mosquitoes in public areas and of crop-damaging insects in agriculture.
• Physical properties: Colorless to pale yellow liquid or solid with a pungent odor
• Uses: Naled is used to control mites, sucking pests and some other insects in a wide variety of crops. It is also used for the control of public and animal health pests including mosquitoes. Insecticide used for control of spider mites, sucking and chewing insects in fruits, vegetables and ornamentals. Its use may be restricted. A cholinesterase inhibitor. Insecticide; acaricide. Insecticide; acaricide.
