BIODIVERSITY, DISTRIBUTION AND MORPHOLOGICAL CHARACTERIZATION OF MACROFUNGI IN SYLHET AND MOULVIBAZAR UNDER TROPICAL EVERGREEN AND SEMI-EVERGREEN FOREST REGIONS OF BANGLADESH AHMED, TANZIM Tropical evergreen and semi-evergreen forest regions under Sylhet and Moulovibazar districts which is located at 24.8917°N and 91.8833°E, in the north eastern region of Bangladesh. A total of 53 macro fungal samples were collected and identified to 15 genera and 25 species. The predominant species were Ganoderma tsugae, Ganoderma applanatum, Ganoderma bonninese, Agaricus bernardii, Coprinus disseminates, Daeleopsis confragosa, Schizophyllum commune, Pleurotus ostreatus, Pleurotus populinus, Mycena epiptergia, Steccherinum ochraceum and Steccherinum ciliolatum.The maximum frequency (37.5%) was recorded for Ganoderma tsugae and Pleurotus ostreatus. The maximum density was 26.8% recorded for Coprinus sp.. The predominant families were Ganodermataceae, Agaricaceae, Polyporaceae, Schizophyllaceae, Pleurotaceae, Mycenaceae and Steccherinaceae. The specimens were deposited to the Sher-E-Bangla Agricultural University Herbarium of Macro Fungi (SHMF). This is the first details investigation macrofungi recorded from Sylhet and Moulovibazar regions of Bangladesh.

ISOLATION AND IDENTIFICATION OF SOIL MICROORGANISMS IN SELECTED POTATO FIELDS OF BANGLADESH NITU, MUSFIKA AHMED Microorganisms from the rhizoosphere soil was isolated from different potato fields of Bangladesh. Seventeen soil samples were analyzed for the incidence of microorganisms from potato field soils. A total of seven fungal species, one bacterium species and one nematode species were characterized using various isolation and identification methods. The predominant fungi isolated include among others; Alternaria solani, Aspergillus niger, Penicillium sp., Rhizopus stolonifer, Bipolaris sp., Phytophthora infestans , Fusarium oxysporum, Ralstonia solanacearum and Meloidogyne sp.. And individual colonies of fungi, bacteria and nematode were counted from media and compared their presence in soil in respect of different locations of potato fields. The present study aimed to find out the fungal diversity and this was the first reported examination of the microbiological diversity of soil microorganisms of some selected potato fields in Bangladesh.

MANAGEMENT OF EARLY BLIGHT OF TOMATO THROUGH SELECTED BOTANICALS AND CHEMICAL FUNGICIDES ASHRAFUZZAMAN A study was carried out at the Department of Plant Pathology, Sher-e-Bangla Agricultural University (SAU), Dhaka-1207, Bangladesh during the period from November 2015 to May 2016 in order to find out the management options of early blight of tomato through selected botanicals and chemical fungicides. Eight treatments viz. T 1 (Foliar spray of Bavistin 50 WP @ 1 g/liter), T (Foliar spray of Dithane M-45 @ 4.5 g/liter), T 3 2 (Foliar spray of Rovral 50 WP @ 2 g/liter), T (Foliar spray of Topgun @ 7 g/liter), T (Foliar spray of Neem leaf extract @ 1:3 w/v), T 6 5 (Foliar spray of Marigold leaf extract @ 1:6 w/v), T (Foliar spray of Papaya leaf extract @ 1:3 w/v) and T 8 7 (Control) were used for the present study. BARI released variety BARI tomato 2 (Ratan) was used as planting material. Under the present study, among all the fungicides, T (Foliar spray of Rovral 50 WP @ 2 g/liter) showed the best promising result in terms of lowest disease 3 4 incidence (9.63%) with highest % of reduction (86.75%) over control. In terms of growth and yield contributing parameters, The highest plant height (117.80 cm), number of branches plant -1 (13.80), Number of fruits plant -1 (36.67), Fruit yield plant -1 (1.12 kg) and Fruit yield ha -1 (65.33 t) were obtained from T (Foliar spray of Rovral 50 WP @ 2 g/liter) compared to all the treatments. Botanicals also provided promising results against early blight control of tomato. Among the tested botanicals T (Neem leaf extract @ 1:3 w/v) showed effective control against early blight of tomato followed by marigold extracts. 5 3 A Thesis Submitted to the Department of Plant Pathology Sher-e-Bangla Agricultural University, Dhaka In partial fulfillment of the requirements for the degree of MASTER OF SCIENCE IN PLANT PATHOLOGY SEMESTER: JANUARY- JUNE, 2016
