Used as broad range non-systemic insecticide for fruits, vegetables, maize, ornamentals, tobacco, rice, and other crops; [HSDB]
Comments
No evidence of mutagenicity in studies using hamsters and micro organisms; No reproductive or teratogenic effects observed in three generation, two litter generation study with rats; In a reproductive study with rabbits, minor reproductive toxicity (including decrease in number of implantations and increase in dead fetuses) was observed in the highest dose groups and 3 animals born with skeletal deformations; Caused no skin and mild eye irritation in rabbits; No significant adverse effects besides inhibition of cholinesterase activity was observed in long term feeding studies with rats; No evidence of delayed neuropathy in hens nor skin sensitization in guinea pigs; [INCHEM JMPR] “The average of two baseline respective cholinesterase activity determinations three days apart, with no exposures to enzyme inhibiting pesticides for at least 30 days, is recommended for each worker prior to exposure to cholinesterase inhibitors because of large inter-individual differences in published baseline values. To be established at least once a year. Removal from workplace exposures is recommended until the cholinesterase activity returns to within 20% of baseline.” [TLVs and BEIs]
