Thiophosphoric 0,0- dimethyl- 0-2-isopropyl-4-methyl-6-pyrimidinyl (Diazinon or Diaziton) was stabilized by mixing <2% HNEt2 or NEt3 and <2% surfactants such as polyethylene alkylphenyl, sodium alkylarlysulfonate, laurylbetaine. When the Diazinon(purity 96.7%) was mixed with 0.5% HNEt2 and 2.0% polyoxyethylene alkylphenyl, the decompoing ratio of the Diazinon(at 50≦̸C, 30 day) was 8.3%.
