Abstract

A series of novel diethylene glycol dialkanoates have been synthesized following reaction of diethylene glycol with corresponding acid chlorides. Their structures were confirmed by 1H, 13C NMR and mass spectroscopy. The test compounds exhibited excellent nematicidal activity against the juveniles of reniform nematode, Rotylenchulus reniformis. As compared to the standard nematicide phenamiphos (EC50 0.61 ppm), the four compounds namely diethylene glycol dipropionate (ECM 21.53 ppm), diethylene glycol dibutanoate (EC50 22.16 ppm), diethylene glycol dipentanoate (EC50 24.14 ppm), and diethylene glycol di-(2-ethyl) hexanoate (EC50 23.99 ppm) were identified as most active.
