Studies that would provide information useful for the continued evaluation of the compound: 1. Biochemical evidence that an S431F mutation in acetylcholinesterase-1 of Aphis gossypii mediates resistance to pirimicarb and omethoate (Pest Management Science, 2004); Sister-chromatid exchanges in human lymphocytes induced by dimethoate, omethoate, deltamethrin, benomyl and their mixture. In short-term and long-term studies, the potential toxicity of omethoate was limited by the onset of cholinesterase inhibition.

To date, OPs that are known to cause IMS include bromophos, chlorpyrifos, diazinon, dicrotophos, dimethoate, disulfoton, fenthion, malathion, methamidophos, methyl parathion, mo nocrotophos, omethoate, parathion, phosmet, and trichlorfon. Data on the acute oral toxicity of dimethoate gave LD50 values of about 310 mg/kg bw in rats, 150 mg/kg bw in mice, and 55 mg/kg bw in hens. As the use of dimethoate on crops can give rise to residues of omethoate, and omethoate has been used as a pesticide in its own right, previous Joint Meetings have allocated an ADI to omethoate; however, the primary manufacturer is no longer producing omethoate. 0000031216 00000 n Structure, properties, spectra, suppliers and links for: Omethoate, 1113-02-6. 0000025716 00000 n 0000016622 00000 n 0000026887 00000 n 0000034828 00000 n 0000022464 00000 n 0000013833 00000 n 0000028749 00000 n 0000036211 00000 n 0000019224 00000 n 0000034003 00000 n 0000021519 00000 n 0000034512 00000 n Appendix K.
