ABSTRACT
Coconut wilt pathogen was isolated from basal stem and rhizosphere soil of coconut tree and identified as Ganoderma lucidum on the basis of its morphological and cultural characteristics. Use of plant extract is one of the most promising effective, safe and eco friendly method to eradicate the pathogens from soil. The aim of the present study to investigate the antifungal activity of Eichhorinia crassipes against Ganoderma lucidum at two concentrations (150 mg/ml and 300 mg/ml). Among these concentrations, 300mg/ml was found to be most effective inhibitory activity. Flucanozole (25μg/disc) was used as standard for this study.
Keywords: Coconut, Ganoderma lucidum, wilt, Eichhorinia crassipes.
