ANTIFUNGAL ACTIVITY OF VARIOUS PLANT EXTRACTS/PRODUCTS ON Exserohilum turcicum (Pass.) Leonard

Abstract

Eleven plant products belonging to Liliaceae, Meliaceae, Verbenaceae, Labiatae, Chenopodiaceae, Euphorbiaceae, Leguminosae and Poaceae were screened for antifungal properties against Exserohilum turcicum. The plant products/extracts viz., Alitin (commercial). Allium sativum (bulb extract), Lantana camera (leaf extract), Azadirachta indica (seed extract) and A. indica (commercial oil) were highly inhibitory to spore germination and mycelial growth of the pathogen in vitro. None of these plant products/extracts were promising when tested in vivo.
