BIODIVERSITY, DISTRIBUTION AND MORPHOLOGICALCHARACTERIZATION OF MUSHROOMS IN SOUTHERN REGION OF BANGLADESH
RASHID, SYED NOMANUR
A survey was conducted to identify and study on biodiversity and
distribution of wild mushroom that grow naturally in different area and
different season at southern region in Bangladesh. Forty three species of
mushrooms belonging to 26 genera and 30 family were collected and
identified from different localities in 16 Upazilla of Barisal, Patuakhali,
Borguna, Pirojpur, Jhalokhati districts of southern region in Bangladesh
from July and October, 2013 and 2014. The identified genera were viz.,
Amanita sp., Agaricus sp., Ganoderma sp., Armillaria sp., Alnicola sp.,
Collybia sp., Daedaleopsis sp., Coprinus sp., Cortinarius sp., Hebeloma
sp., Mycena sp., Lepiota sp., Lycoperdon sp., Macrolepiotia sp.,
Crepidotus sp., Marasmius sp., Megacollybia sp., Coprinellus sp.,
Ramariopsis sp., Daldinia sp., Tuber sp., Volvariella sp., Steccherinum
sp., Leucoagaricus sp., Hypholoma sp., and Coprinellus sp. The
maximum frequency of occurrence was exhibited by Ganoderma tsuage,
Ganoderma applanatum, Amanita sp. and Agaricus silvicola (18.75%)
and the maximum density was recorded for Coprinus silvaticus (48.83%).

FORMULATION OF Trichoderma BASED BIOPESTICIDES IN CONTROLING FOOT AND ROOT ROT OF BETELVINE
KABIR, MD. HUMAYUN
An experiment was conducted at Sher-e-Bangla Agricultural University (SAU)
during the period from September 2014 to December 2014 for Formulation and
evaluation of Trichoderma based bio-pesticide for controlling foot and root rot of
betel vine. The effect of nine Trichoderma based substrates viz., T

SCREENING FOR SEED BORNE PATHOGENS AND FIELD DISEASES OF SOME SELECTED EXOTIC VEGETABLES IN BANGLADESH
AKTER, KHALEDA
An experiment was conducted at Horticulture Farm of Sher-e-Bangla Agricultural
University, Dhaka, Bangladesh during the period from October 2013 to March 2014 to
study on screening of seed borne pathogens and field diseases of some selected exotic
vegetables in Bangladesh. Five most popular exotic vegetables were taken for this
experiment namely broccoli, Chinese cabbage, capsicum, squash and lettuce and three most
cultivated varieties were used for each varieties. In seed health test, Aspergillus niger, A.
flavus, Chaetomium sp. were found in broccoli. Whereas, in Chinese cabbage, capsicum and
squash, A. niger and A. flavus were observed. In lettuce seed, Bipolaris sp., Chaetomium sp.
and Curvularia sp. were identified. In seed bed, Alternaria leaf spot was found in broccoli
and Chinese cabbage seedlings. Whereas, damping off was observed in lettuce seedlings.
Besides this, powdery mildew was found in squash and mosaic disease was observed in
capsicum and squash seed bed. In field condition, disease incidence and severity were
recorded at three different times during growing seasons. Alternaria leaf spot (Alternaria
spp.) was found in broccoli, Chinese cabbage and lettuce and the highest incidence and
severity of alternaria leaf spot was recorded in Premium Crop variety of broccoli (19 and
8%). In Chinese cabbage, the highest incidence and severity of alternaria leaf spot was
found in Big King (24 and 6.67%) and in case of lettuce, the highest incidence and severity
of alternaria leaf spot was observed in Green Wave variety (13.67 and 4%). Mosaic (CMV)
disease was observed in capsicum and squash and in capsicum the highest mosaic incidence
was recorded in Capsicum First 104 (36.33%) and in squash the highest incidence of mosaic
disease was observed in Hybrid Squash (28.33%). In case of powdery mildew (Oidium sp.)
the highest disease incidence was found in Squash F
1
Barbuda (42.33%). In capsicum for
leaf curl (YLCV) disease the highest disease incidence was observed in Sweet pepper
(31.67%). The yield was showed significant variation among the varieties. In case of all
diseases, it was observed that disease incidence and severity was gradually increased with
the age of the plant and minimum incidence and severity gave the maximum yield.

SEED HEALTH STATUS OF COMMONLY USED THREE SELECTED HYBRID MAIZE VARIETIES IN BANGLADESH
JINNAH, MOHAMMAD ALI
Experiment was conducted to know the seed health status of three selected
hybrid maize varieties viz. Dekalb, Miracal and NK-40 during the period July-
2013 to August-2014 at the Department of Plant Pathology, Sher-e-Bangla
Agricultural University, Dhaka, Bangladesh. Seed health study was conducted
following blotter method, water agar test tube method and rolled paper towel
method. It was revealed that seeds of selected maize varieties yielded three
fungal species in blloter method. The fungi were Aspergillus flavus (7.42% in
NK-40, 5.95% in Miracal and 2.24% in Dekalb), Aspergillus niger (7.32% in
NK-40, 6.98% in Miracal and 4.22% in Dekalb) and Fusarium moniliforme
(5.75% in NK-40, 4.42% in Miracal and 3.42% in Dekalb). In seedling
symptoms test by water agar test tube method and seedling vigor index test by
rolled paper towel method, maize variety Dekalb showed good performance in
terms of minimum number of diseased seedlings (15.26%) and dead seed
(2.00%) and maximum germination (97.25%) and showed the highest vigor
index (1437) while the variety NK-40 showed poor performance regarding all
parameters used. So, most of the seed-borne pathogens reduced the germination
and produced diseased seedlings. Farmers are therefore, advised to collect the
seeds from reliable source and check their maize seed health status before
sowing in the field.
