Abstract
Four experiments were conducted to evaluate commercial bio-fungicides for the
management of foot and root rot disease of lentil at Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during November 2019 to April 2020 following CRD and
RCBD design with 3 replications for in vitro and in vivo experiments, respectively.
Susceptible variety BARI Masur -1 (Utfala) was used in this experiment. Nine
Trichoderma based commercial bio-fungicides viz. G-derma (powder), Bio-derma
(powder), Decoprima, Recharge, Bio-derma (peat soil), G-derma (LDS), Terrabio,
Decohumate, Ttricost and two chemicals viz. Formaldehyde and Autostin were assessed
in this study. In pot experiment, seed treatment with bio-fungicides was done and the
lowest disease incidence (6.48%) was recorded from T
(Tricost) and the highest disease
incidence (54.91%) was observed from T

(Control). Significantly the highest yield /pot
(12.55 g) was found in T
(Tricost) treatment. In another pot experiment, soil treatment
with bio-fungicides was done and the lowest disease incidence (4.84%) was recorded
from T

(Bio-derma - peat soil) and the highest disease incidence (53.29%) was observed
from T

(Control). Significantly the highest yield /pot (16.83 g) was found in T
(Bioderma-
Peat soil) treatment. Moreover, in case of seed and soil treatment with biofungicides,
the
lowest
disease
incidence
(4.87%)
was
recorded
from
T
(Decoprima) and
the highest disease incidence (49.92%) was observed from T

(control). Significantly the
highest yield /pot (17.83 g) was found in T
(Decoprima) treatment. In field experiment,
the lowest disease incidence (10%) was recorded from T
4
(Tricost) and the highest
disease incidence (48.89%) was observed from T
0
5
(Control). The highest yield /plot
(437.67 g) and yield/m

(145.89g) found in T
(Tricost) treatment. Thus, seed and soil
treatment with Trichoderma based bio-fungicides significantly reduced foot and root rot
disease of lentil.
