Abstract/ Executive Summary:

Three spp. of Trichoderma such as T. viridae, T. Koningi, T. harizanum were taken from pure culture to find out antagonistic activity against five fungal pathogesns of jute such as Mcarophomina phaneolina, Botryodiplodia theodromae, Rhizoctonia solani, Sclerotium rolfsii and Glomerella cingulata. Maximum inhibition of radial growth of jute pathogen was recorded against Rhizoctonia solani, Sclerotium rolfsii and Glomerella cingulata against Trichoderma viridae.

Keywords: Biological control, Jute, Pathogen, Trichoderma sp.

Location: Central station, Dhaka

Start Date: 15-03-2005

End Date: 30-11-2005

Program Area: Pest Management

Commodity: Jute

Objectives:

1.To minimize the use of fungicide

2.To find out suitable methods for controlling fungal organism

Methodology:

The experiment was conducted in Plant pathology laboratory and the experiment was set in dual culture method following CRD with three replications. Five mm b;lock culture media of 3 sp. of Trichoderma were placed aseptically on 90 mm PDA plates opposite to each other at 70 mm apart with 4 replications for each jute fungal pathogens. PDA plates inoculated only with five mm diameter culture block of any particular jute pathogens served as control
