Abstract:
Experiments were carried out at the central farm and Laboratory of the Department of
Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka-1207, during the
period from December 2017 to March 2018 to investigate the effect of different
management options on the foot and root rot disease of lentil. The field experiment was
conducted with RCB design with nine treatment and three replications. nine treatments
were comprised of two chemicals viz. Autostin 50 WP and Indofil M-45, one biofungicide
Trichoderma
harzianum,
one
botanical
fungicide
Allamanda
extract,
A
soil
amendment
by poultry manure and one control. The chemical fungicides, plant
extracts, bioagent spore solution were applied as seed treatment as well as spraying at
the basal part (root zone) of the plant. Data were collected at different days after
sowing. Results showed that the yield and yield contributing characters as well as
growth parameters had been significantly affected by different treatments applied.
Among different management options the treatment comprising seed dressing with
Indofil M-45 and field spraying with Autostin 50 WP gave the best results regarding
the number of pods/ plant, plant height, 1000 seed weight/ plot and seed yield/ plot
followed by Trichoderma harzianum spore solution. The height percentage of disease
incidence has been recorded in case of control and showed the maximum amount of
yield loss. The treatment where the lentil seed were treated with Autostin 50 WP (0.4%)
followed by field application with Autostin 50 WP (0.2%) at 7 DAS gave the promising
performance showing upto 56% higher effect of lentil.
