ABSTRACT: The aim of this study was
to determine the prevalence of seed-borne fungal pathogens of jute and their
control with plant extract. The experiment was carried out in seed pathology
centre, Bangladesh Agricultural University to obtain relevant information about
the health of jute seeds and find out the efficacy of extracts as seed-treater.
Two varieties viz., Deshipat (Corchorus capsularis) and
Tossapat (Corchorus
olitorius) were selected for this study and jute seeds were collected from two
different locations of Bangladesh. The major predominant identified fungi were Colletotrichum corchori, Macrophomina phaseolina, Fusarium spp.,
and Botryodiplodia theobromae. Least
seed-borne fungi were found in the variety of Tossapat. Low germination of
seeds was found related to high prevalence of seed-borne fungal infections.
Highest seed-borne infection was obtained in the variety of Deshipat. In this
study, we evaluated some major plant extracts such as garlic clove (Allium sativum), neem
leaves (Azadirachta indica),
allamanda leaves (Allamanda
cathartica L.) and
marigold leaves (Tagetes spp.) for
observing the action of these plant extracts on seed borne fungi of Jute. The
study revealed that the extract of Garlic (Allium
sativum), and
Biskatali (Polygonum
hydropiper) increased the germination of seeds and garlic(Allium sativum) extract was
also found to be most effective in controlling the seed-borne infection among
all the treatments. Although the inhibiting capacity of the extracts of
Allamanda (Allamanda cathartica L.) and Biskatali (Polygonum
hydropiper) was found to be similar
and Biskatali extract
was found to have the second position among all the treated plant extracts in
inhibiting the growth of isolated fungal pathogens.
