A survey report of leaf spot diseases of certain medicinal plants of Maharashtra, India.

Abstract

Because of great variation in soil texture and other environmental factors, those are thousands or more than 2000 varieties of medicinal plants (Jose and Rayalaxmi, 2005). The medicinal plants are affected by fungal pathogens which degrade the quality of medicinal plant directly by disturbing the physiological and metabolic procedures of affected plant parts. Total 2 medicinal plants selected for the study were Kanghi (Abutilon indicum), Arusa (Adhatoda vasica), Aegle (Aegle marmelos), Ghee Kumar (Aloe vera), Neem (Azadiracta indica), Sant (Baerhavia diffusam), Dhak (Butea monosperma), Madar (Calotropis procera), Tarwar (Cassia auriculata), Turmeric (Curcuma long), Kala Datura (Datura fastuosa), Bhrangray (Eelipta alba), Amla (Emblica officinales), Dudhia (Euphorbia hirta), Jasmine (Jasminum officinale), Kaner (Narium adoratum), Kali Tulsi (Ocimum canum), Castor (Ricinus communis), Ritha (Sapindus triloliatus), Kateli (Solanum anthacarpum) and Arguma (Terminalia aryuna). The pathogenic fungi responsible for leaf spot diseases of medicinal plants were isolated on PDA (Potato dextrose agar) medium by food poisoning technique. The fungi were identified on the basis of growth pattern and spore types. The fungi responsible for leaf spots of various medicinal plants were Phyllachora, Phyllosticta, Septoria, Colletotrichum, Carynespora, Chaetothyrium, Stenella, Oestalotiopsis, Pseudocercospora, Fusarium, Myrothecium, Drechslera, Ciliochorella, Curvularia, Pseudodiploidia, Phoma, Mycosphaesella and Septoria.
