O,O-Dialkyl thiophosphate esters of eugenol namely, O-(4-allyl-2-methoxyphenyl) O,O dimethyl thiophosphate and O-(4-allyl-2-methoxyphenyl) O,O-diethyl thiophosphate were prepared, characterized and screened for insecticidal and fungicidal activity. The diethyl derivative was found to be more toxic to Rhizopertha dominica (Lesser grain borer) than eugenol and the methyl derivative was similar to eugenol in toxicity to this insect. However, these compounds were found to be fungicidal even after eugenol was derivatized to the thiophosphates.
