Abstract
The experiment was conducted at the Plant Pathology Laboratory and the net house of
Plant Pathology Department, Sher-e-Bangla Agricultural University, Sher-e-Bangla
Nagar, Dhaka -1207 during June’ 2018 to March’ 2019. Nine fiber crops varieties were
used for conducting the experiments viz., V

= Jute cvl-1, V
= BJRI deshi jute-5 (0795),
V

and V

= Kenaf (HC-95), V

= Mesta (HS-24). All seed samples were collected from Bangladesh Jute
Research Institute (BJRI), Manik Mia Avenue, Dhaka. In Blotter method, the highest
total number of seed borne fungi (7.00) was recorded in V
and five fungal genera (C.
corchori, Fusarium spp., Aspergillus spp., B. theobromae, M. phaseolina and
Curvularia lunata) were identified in jute and allied fiber crop varieties. In Water agar
method, the highest total numbers of seed borne fungi (5.67 and 5.33) were recorded in
V
4
and V
5,
5
respectively and five fungal genera (C. corchori, Curvularia lunata,
Fusarium spp., Aspergillus spp., and M. phaseolina) were identified. In Test tube
method, the highest total number of seed borne fungi (2.00) was recorded in V
and
V
, respectively and 4 fungal genera (C. corchori, Fusarium spp., Aspergillus spp., M.
phaseolina). In growing on test method, the highest total number of seed borne fungi
(3.67) was recorded in V
4
and altogether four fungal genera (C. corchori, Fusarium
spp., Aspergillus spp. and B. theobromae) were found. In this findings, the highest %
seedling incidence (83.33%; 80% and 66.67%, respectively were found in control
withurrt treatment) where the lowest results (24.14%; 21.43% and 42.86%,
respectively) were found in Autostin treatment in case of severely infected 3 varieties
of jute and allied fiber crops seed namely V

and V
, respectively . For growth
performance, the highest % germination (91.67%), root length (7.21 cm), shoot length
(31.17 cm) and leaf number (17.21) was observed in the T
