BIOCONTROL POTENTIAL OF PARMOTREMA SPECIES AGAINST COLLETOTRICHUM CAPSICI ISOLATED FROM ANTHRACNOSE OF CHILLI
Journal Title: Journal of Biological and Scientific Opinion - Year 2014, Vol 2, Issue 2
Abstract
Chilli is an important commercial crop and is consumed as spice as well as vegetable. Colletotrichum capsici is an important fungal pathogen causing anthracnose in chilli. The objective of the present study was to determine inhibitory activity against C. capsici of extracts of three foliose macrolichen species of the genus Parmotrema viz., P. tinctorum, P. grayanum and P. praesorediosum from Western Ghats of Karnataka, India. The antifungal effect was checked in terms of mycelial growth inhibition by Poisoned food technique. The spore suspension of C. capsici was inoculated on the centre of Potato dextrose agar plates (control and poisoned). The colony diameter of fungus in control and poisoned plates was recorded on 5th day of incubation. The lichen extracts caused marked inhibition of test fungus as revealed by reduced colony diameter of test fungus in poisoned plates. Among lichens, P. tinctorum showed potent inhibitory activity and caused > 50 % of inhibition of test fungus. The lichens of the present study appeared promising as bio control agents against C. capsici.
