EFFECT OF DIFFERENT VEGETABLE-GRAINS MEDIA ON VARIABILITY IN MYCELIAL GROWTH PATTERN AND SCLEROTIA FORMATION OF RHIZOCTONIA SOLANI

Abstract

Rhizoctonia solani is one of the most important soil-borne fungal pathogen causing significant yield losses in many agriculturally important crops globally. In the present investigation, several different vegetable-grains culture media viz., Rice Dextrose Agar (RDA), Maize Dextrose Agar (MDA), Beet Dextrose Agar (BtDA), Nutrient Dextrose Agar (NDA), Potato Dextrose Agar (PDA), Carrot Dextrose Agar (CDA), Maize Potato Dextrose Agar (MPDA), Banana Dextrose Agar (BDA) and Brinjal Dextrose Agar (BrDA) were evaluated to find out the appropriate media for growth and sclerotia formation of R. solani. Out of nine different culture media tested, maximum mycelial growth and sclerotia formation was recorded in MPDA while minimum mycelial growth was recorded in RDA. Maximum diameter of sclerotia wasrecorded in BDA.
