Background and overview[1]
The scientific name of iodofenphos is O,O-dimethyl-O-(2,5-dichloro-4-iodophenyl)thiophosphate, and its common name is iodofenphos. Colorless crystal, melting point 76℃. The solubility in water at 20℃ is lower than 0.002g/L, and it is soluble in acetone, benzene and methylene chloride. Unstable in strong acids and alkalis. It is prepared by the reaction of O,O-dimethylphosphorothioate chloride and sodium 2,5-dichloro-4-iodophenolate.

Iodophos is a contact-killing and stomach-toxic insecticide and acaricide. Currently, it is usually used in combination with other ingredients, such as preparing new pesticide combinations, including ethiprofen as component A, and organophosphate compounds as component B. The organophosphate compounds are selected from: chlorpyrifos Silicone oil emulsion (methyl/ethyl), methamidophos, acephate, methylpyraphos, benzophos, benzophos, ethyl bromide initiator thiophos, bromophos (methyl), Tetrathion, thiophos, trithion, oxychlorine, methionine, methionine, pyrothion, benzonitrile, fenitrothion, methionine, methyl phosphonate, sulfonate, Chloromethionine, diazinon, ethionide, dichlorvos/DDVP, dimethoate, dimethoate, methylmethionine, vegophos, acetophos, benzophos, ethionate, dimethoate, ethiphos Pyrithion, valfenphos, difenthionate, fenitrothion, fensophos, fenthion, pyrifluthion, difenthion, fenthion, fenfenthion, thiazophos, heptenophos , iodophos, isopyrazine, flufenphos, isosaphos, O-isopropyl salicylate, oxazophos, malathion, phosphos, pyrophos, fenfos, sulfate Phosphorus, monocrotophos, dibromophos, omethoate, sulfoxide, parathion (methyl/ethyl), rice powder, phorate, phosphos, imidion, phosphorus amine, Profenfocarb, phoxim, pyrimidinphos (methyl/ethyl), profenofos, propofophos, profenfos, prothion, pyridathion, pyrazothion, pyridazinophos, pyridathion , quinalphos, sebufos, fenfos, thipropion, butylpyrimidinphos, dithion, terbufos, fenfos, methylacetate, triazophos, triclorfon, aphidphos, all The combinations show surprisingly good insecticidal activity.
