Abstract
AbstractWe report the toxicological effects of new series of biorational glycol esters and compare the efficacy with the known commercial sugar ester, sucrose octanoate. Ethylene glycol diesters were easy to prepare without any isomeric constraints and very safe compounds that were applied as sprays or as residues. The compounds were equally toxic to mustard aphid, Lipaphis erysimi nymphs and adults and the activity was significantly comparable with sucrose octanoate activity. In spray assays LC50 of various compounds ranged from 1.32 to 11.5 mg/ml and in residual assay the range was 20.3–51.4 μg/cm2. In residual assay, ethylene glycol di‐2‐ethylhexanoate (5) and dioctanoate (6) were as effective as sucrose octanoate. Structure activity relationship suggested that higher number of carbon chains in these two compounds may be playing a role in the stability of compounds under residual operation of the insecticide. Based on these results, glycol esters would be useful and easy to prepare biorational compounds in integrated pest management.
