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 Peat soil + Rice bran + Water), T 2 1 (Trichoderma + (Trichoderma + Peat soil + Wheat bran + Water), T (Trichoderma + Peat soil + Lentil bran + Water), T (Trichoderma + Peat soil + Gram bran + Water), T 5 4 (Trichoderma + Peat soil + Black gram bran + Water), T (Trichoderma + Peat soil + Mustard oil cake + Water), T (Trichoderma + Peat soil + Grass pea bran + Water), T 8 7 ( Trichoderma + Peat soil + Saw dust + Water), T (Control) were evaluated for growth and sporulation of Trichoderma harzianum and acting against Sclerotium rolfsii for the management of foot and root rot of betel vine. The effect of the treatments varied significantly in terms of production of Trichoderma spore and reducing foot and root rot diseases in comparison to control. Among the treatments, soil application with T 1 (Trichoderma + Peat soil + Rice bran + Water), T (Trichoderma + Peat soil + Wheat bran + Water), T (Trichoderma + Peat soil + Lentil bran + Water), T 4 3 (Trichoderma + Peat soil + Gram bran + Water) and T (Trichoderma + Peat soil + Black gram bran + Water) completely control foot and root rot of betel vine. 5 3 6 9 2 No plants were infected in case of application of T 1 , T 2 , T 3 , T 4 and T while 100% plants were infected in control treatment. 5 A Thesis Submitted to the Faculty of Agriculture Sher-e-Bangla Agricultural University, Dhaka, in partial fulfilment of the requirements for the degree of MASTER OF SCIENCE IN PLANT PATHOLOGY SEMESTER: July – December 2014

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.
