Abstract/ Executive Summary:

Jute suffers from various fungal diseases and subjected to yield and financial loss of the jute growers. Among the fungal diseases, stem rot, anthracnose and black band are the major and caused by Macrophomina phaseolina, Botryodiplodia. theobromae and Colletotrichum Corchori, respectively. Among the other fungal diseases, soft rot and root rot caused by Sclerotium rolfsii and Rhizoctonia solani, respectively and also cause considerable yield loss. Plant Pathology Department, Bangladesh Jute Research Institute has screened a number of fungicides since it’s inception. Among all the screened fungicides, Dithane M-45, Onthane, Mannere (Mancozeb) were recommended as foliar spray. The present study was under taken as per decision of Pesticide Technical Advisory Committee meeting for field trial of supplied fungicides to increase the number of fungicides, for controlling the fungal diseases of jute and allied fine crops.

Program Area: Pest Management

Commodity: Jute, kenaf, Mesta

Objectives:

To control the fungal diseases of jute and allied fine crops.

Methodology:

Promising fungicides were tested in the field to find their effects against different fungal diseases of jute in the field of JAES, Manikgonj. Jute variety CVL-1 was used for evaluation of new chemical fungicides Asset 10 EC, Akota 10 EC, Aconazole5EC, Starzole 100 EC, Bondaze 80 WP and Dithane M-45 along with control (No spraying). The experiment was conducted with 4 replications. Three sprayings were adopted in each experimental plot during the whole cultivation period. Stand data was recorded after final thinning. Number of healthy plants and disease plants were recorded in different plots after first spraying that is 1 month after final thinning. Number of healthy plants and diseased plants were recorded after 2^nd. and 3^rd spraying of the fungicides.

Achievement/Findings:

The highest percent reduction of fungal diseases (82.34 %) was recorded in plots spraying Dithane M 45 followed by 79.40 % reduction in jute plots sprayed with Starzole 100 EC. The lowest fungal disease reduction was recorded in control plot (55.79%) at before harvest of crop.
