Cultural characterstics of Cercospora beticola sacc. causing leaf spot of palak

Abstract

Palak (Beta vulagaris var. bengalensis Hort.) is one of the most popular leafy vegetables widely grown in India. This crop is severely affected by leaf spot disease caused by Cercospora beticola leading to brown coloured spots on the leaves which hinders the market quality of the leaves. All media are not equally good for all fungi, nor there is a universal substrate or artificial medium, upon which all fungi can grow. So, different media including both synthetic and non-synthetic were tried for C. beticola in the present experiment. Cultural studies of C. beticola grown on different solid media showed that Potato dextrose agar and Oat meal agar were good for growth. Among the nine liquid media evaluated, maximum dry mycelial weight of the fungus was obtained in Soypeptone broth which was significantly superior to all other media. Temperature requirement of the fungus was found 25°C where good growth was observed. How to view point the article : Poornima and Hegde, Yashoda R. (2014). Cultural characteristics of Cercospora beticola sacc. causing leaf spot of palak.

Performance variation in growth and sporulation of isolates of Alternaria alternata Fr. Keissler causing blight disease in Mulberry

“…The synthetic media viz., Leonions's agar, Glucose-peptone agar and Sabourand's agar and non-synthetic media, Oat meal agar and PDA were excellent for the mycelial growth and conidial production of A. alternata. These results were in agreement with findings of Poornima and Hegde (2014) [6] wherein they opined that PDA and Oat meal agar media were the best media for the growth and sporulation of Cercospora beticola Sacc. These results were in validation with the findings of Poornima (2010) [7] wherein she reported that PDA and Oat meal agar supported the growth of C. betiocola.…”

Culture Media Options for Growth and Morphological Characterisation of Cercospora coffeicola Affecting Coffee in Zimbabwe

“…This is in agreement with our observations in which MEA reached maximum growth in 7 days after inoculation. In a study by Poornima and Yashoda [33] , twelve solid media were evaluated and maximum growth of C. beticola was observed on PDA (89.66 mm) and Oat meal agar (81.67 mm), with MEA following behind (79.67 mm). These results are contrary to the findings of this current study, where MEA was the best followed by PDA, with oat meal agar being the least in Cercospora coffeicola growth.…”
