Abstract:
An experiment on management of mungbean yellow mosaic virus (MYMV) was
conducted in the field of SAU central Farm of Sher-e-Bangla Agricultural
University, Dhaka during April to July, 2015.The prime aim of the study was to
manage of Mungbean yellow mosaic virus (MYMV) by using one newly release
botanical and through insect control. BARI released variety BARI mung-5, and
three insecticides (Imidacloprid, Acmix and Sobicron) and one botanical
nutrients PPN (Peak performance nutrients) was used in the experiment. The
plants were grown for pulse production and natural inoculums were relied upon
for the infection of MYMV. Growth parameters, yield attributes and
physiological features were significantly affected by application of selected
insecticides and PPN combinations. Disease incidence and severity of MYMV
was significantly varied among the treatments. Application of Imidacloprid
with PPN combination gave the lowest disease incidence (3.13, 5.24 and 6.24
% per plot and 14.33, 15.49 and 21.87 % per plant) at 30, 40 and 50 DAS,
respectively while the highest disease incidence (7.77, 13.70 and 19.24 % per
plot and 39.33, 48.20 and 56.63 % per plant) were found in control at 30, 40
and 50 DAS, respectively. Application of Imidacloprid with PPN also gave the
lowest disease severity (5.00, 6.00 and 13.33% at 30, 40 and 50 DAS,
respectively while the highest disease severity (27.33, 35.00 and 45.00%) at 30,
40 and 50 DAS, respectively were measured in control treatment when no
insecticides and PPN was used. The highest chlorophyll content number of
flower, pod and yield was also measured in case of combined application of
Imidacloprid and PPN (Peak performance nutrients).
