abstract：:Ethiofencarb is one of the carbamate compounds, which are, in general, less toxic than organophosphorus insecticides. This is due to their reversible acetylcholinesterase inhibition and relative inability to cross the blood-brain barrier. Generally, ethiofencarb is regarded to be of low toxicity (LD(50) > 200 mg/kg); ...
