Bangladesh Agricultural university one of the leading Agricultural university of the South Asia. This University was situated in Mymensingh, Bangladesh. Department of Plant Pathology is a royal Department of this university.
In the year of 2012, an exclusive experiment was conducted in Department of Plant Pathology.
The Title was that Experiment Was: "Isolation of Trichoderma spp from different location of Bangladesh and determination of their antifungal Feature"
The research work was carried out to identify antifungal Trichoderma isolates from the rhizosphere to control soil borne plant pathogenic fungi. Ten Trichoderma isolates were isolated from the soil samples collected from different locations of Bangladesh. Their morphological characters and antifungal feature was studied. Colony diameter varied from 30.50 mm to 90.00 mm. The isolates were categorized into different groups based on their colony properties. On the basis of colony color, isolates were grouped into five such as dark green, green, light green, yellowish green and whitish green. Maximum isolates were green and light green. On the basis of growth habit and colony consistency the isolates were categorized into three groups, in which most species had fast growth and were compact in appearance. Different selected temperature such as: 20o, 25 o, 30o and 35 o C were maintained in incubators to observe the growth of different Trichoderma isolates. It was found that Trichoderma grew well at 25-30ºC. Antifungal activities of all Trichoderma isolates were tested against seven fungal mycoflora viz. Penicillium sp, Fusarium oxysporum, Sclerotium rolfsii, Rhizoctonia solani, Aspergillus flavus, Colletotrichum gloeosporiodes and Phomopsis vexans by duel culture method. All isolates of Trichoderma showed wide variation in growth inhibition against these pathogens. Among all of the Trichoderma isolates, ST5 was strongly inhibited the growth of all the pathogenic fungi.
