Abstract:
The experiment was conducted in the experimental field, Central Farm, allotted for
the students of Department of Plant Pathology, Sher-e-Bangla Agricultural
University, Dhaka-1207, during November 2020 to April 2021 to find out best
ecofriendly management for blast disease of wheat. Three variety Prodip, BARI Gom26
and
BARI
Gom-28
was
tested
to
find
out
highest
germination
percentage
and
blast
disease
incidence (%). Among these varieties Prodip showed highest germination
(93%) and blast disease incidence (30%). Seven treatments, viz. T
1
=
Garlic clove extracts, T
3
= Aloe vera leaf extracts, T
4
= Control, T
2
= Black cumin seed extracts, T
5
=
Neem leaf extracts, T
6
= Nativo 75 WG and T
7
= Provax 200 WP, were used for blast
disease management. The experiment was laid out in Randomized Complete Block
Design (RCBD) design with three replications. Data were recorded on blast disease
incidence (%), disease severity, growth and yield components of wheat. Experiment
results concluded that among all treatments T
7
(Provax 200 WP) and T
5
(Neem leaf
extract) performed better compared to other treatments for controlling blast disease of
wheat. With T
7
(Provax 200 WP) treatment the lowest blast disease incidence (%)
recorded was 7.86, 9.86 and 10.19, respectively, during the milking stage, soft dough
stage, and hard dough stage of wheat. With T
5
(Neem leaf extract) treatment, a
statistically equivalent reduction in blast disease incidence (%) was observed. During
the milking stage, soft dough stage, and hard dough stage of wheat, the lowest blast
disease severity was 1.03, 1.23 and 1.63, respectively, with T
7
(Provax 200 WP)
treatment. A statistically similar reduction in blast disease severity was found with T
5
(Neem leaf extract). Therefore, it could be concluded that the treatment T
5
(Neem leaf
extract) would be recommended as ecofriendly management for blast disease of
wheat.
