Abstract: Vigna mungo
is a plant having good nutritional values and medicinal importance and it plays
a significant role in human nutrition. Many recent studies have been conducted
on the nutritional quality of V. mungo (Hussain et al., 2010; Blessing and
Gregory, 2010). The studies suggest that this bean is a good source of protein,
carbohydrate and minerals (Agugo and Onimawo, 2009; Suneja et al., 2011). Its
medicinal uses are reported in different traditions of medicine such as
Ayurveda and Unani. It is mostly used for therapeutic purposes and is known to
posses antihypertensive and antidiabetic properties (Lin et al., Gary, 2006;
Yang et al. 2008). This plant is severely attacked by various fungal pathogens.
A periodical survey was conducted during the month of November-2012 to
March-2013 to collect infected leaves of V. mungo from five different locations
of Raipur district viz. Indira Gandhi Krishi Vishvavidyalaya, Raipur, two
villages Jora and Bhatagaon, farm house and kitchen garden of Kushalpur Raipur.
Severe brown spots were observed on the plants of Vigna mungo for
phytopathological investigation. Total two fungal pathogens have been isolated
from the leaves of the crop. Fusarium semitectum (FS). Corynespora cassiicola
(CC) were isolated from leaves showing reddish brown, circular, regular and
necrotic spots. Leaves were severely damaged in both symptoms and both species
of Fusarium semitectum (FS Corynespora cassiicola showed severe degree of
infection and diseases intensities. Pathogenicity test was proved by Koch's
postulate. Conidial size was measured using micrometry. Suitable control and
protective measures should be taken into account to prevent this major kharif
crop from the microbial invasion so as to get a healthy crop of immense
nutritive value.
