Notes: Methomyl-d3 is intended for use as an internal standard for the quantification of methomyl (Item No. 25610) by GC- or LC-MS. Methomyl is a carbamate insecticide and molluscicide.{37786,43317} It induces mortality of tobacco budworm larvae when applied at a concentration of 0.56 kg/ha and southern armyworm larvae at concentrations of 0.01 and 100 ppm.{37785} Methomyl is toxic to the land snail M. obstructa (LD50 = 11.9 µg/snail).{43317} It is also toxic to rats via oral but not dermal administration (LD50s = 30 and >2,000 mg/kg, respectively).{37786} Formulations containing methomyl have been used in the control of insects in agriculture.
