Title

Cotton Boll Weevil Antifeedant Activity And Antifungal Activity (Rhizoctonia Solani And Pythium Ultimum) Of Extracts Of The Stems Of Wedelia Biflora

Abstract

Extracts of the stems of the Thai plant Wedelia biflora (Linn.) DC (Compositae) were shown to have antifeedant activity against the cotton boll weevil (Anthonomus grandis Boh.). This activity also prompted an investigation of antifungal properties. Five compounds with antifeedant and/or antifungal activity were isolated. They include 16-methylkaur-15-en-19-oic acid, 24-ethylcoprostanone, stigma-7-en-3-ol, stigmasterol, grandifloric acid, and ent-kauradienoic acid. 16-Methylkaur-15-en-19-oic acid and grandifloric acid showed antifungal activity against the fungi Pythium ultimum (240% and 70%) and Rhizoctonia solani (280% and 78%). 24-Ethylcoprostanone and enf-kauradienoic acid showed antifeedant activity against the cotton boll weevil (90% and 83%). © 1990, American Chemical Society.
