Abstract/ Executive Summary:

There were no significant difference among the indigenous plant product i.e they seemed to be equally effective in comparison with control. In case of chemical fungicides Noin was found effective. Percentage of germination was higher in treatment 5%.The treatments (doses) of 0.6%, 0.5%, 0.4% had no real difference. Negligible percentage of seed borne fungus was found in treatment no. Noin 0.3% and 0.4%. No fungal organism was identified in 0.5% and 0.6% treatment.This experiment was carried out in green house for further confirmation

Keywords: Screen, Indigenous, Plant products, Chemical fungicide, Seed ,

Location: Green house, BJRI,Dhaka

Start Date: 30-03-2001

End Date: 30-10-2001

Program Area: Pest Management

Commodity: Jute

Objectives:

1. To find out suitable indigenous plant products for jute seed treatment.

2. To find out the active ingredient responsible for controlling the growth of pathogens.

3.To attention is also paid to other indigenous medicinal medicinal plants plants which could be as seed dressing agent like garlic.

Methodology:

Fine paste of leaves of Mehdi ( Lowsinia alba ) , extract of algae and jute seed oil was prepared. 50 gm of seeds were mixed throughly with each ingredient and dried properly. These treated seeds was tested in the laboratory for seed health by blotter and agar method. If the result was positive this treated seeds was then sown in green house pots. Evaluation of the fungistatic and fungicidal activities of the mentioned ingredients was done in the laboratory by counting spore germination and observing growth rate of the pathogenic organisms associated with jute seed. The same procedure was followed by garlic capsule also. Following records were kept: 1.Measurement of growth rate of the pathogens in PDA where the tested ingredient was mixed in different dilution. 2.Spore germination test of the respective pathogen. 3.Germination and diseased percentage of the planted seeds. 4.Germination and diseased percentage of treated and untreated seed in the green house.
