Abstract/ Executive Summary:

A survey program was conducted at different commercial seedling producing nurseries and farmer’s field to observe the percentage of nematode infection and infestation. Four different vegetables viz. tomato, Egg plant, Cabbage and Cauliflower seedlings were collected from ten districts of the country. Root Knot nematode infestation varied from 0-100% in the selected locations.

Program Area: Socio-economic and Policy

Commodity: Diseases

Objectives:

To know the status of nematode association with the seedlings.

Methodology:

Seedlings of four different vegetables namely, Tomato, Egg plant, Cabbage and Cauliflower collected from different commercial vegetable seedling growing nurseries viz. BADC farm, HRC farm and farmer’s nursery bed. In each location 25 seedlings and 20 gm rhizospheric soil were collected. Moreover, collected soil and plant sample were brought to the lab of Plant Pathology Division, BARI, Gazipur. The root zone area was observed under the Stereomicroscope and the percentages of infection were recorded. Moreover, the number of nematode population was counted by placing the soil on Baermann funnel by following the Baermann funnel technique.

Achievement/Findings:

Ten districts viz. Dinajpur, Bogra, Comilla, Joypurhat, Mymensingh, Netrokona, Kishorganj, Barisal, Faridpur and Gazipur were selected to collect the vegetable seedlings. In all the area seedlings were found to be infected by root knot nematode whereas seedlings of HRC farm Mymensingh were the most infected followed by HRC farm, kishorganj. On the other hand, the highest number nematode populations were recorded in HRC farm, Kishorganj followed by HRC farm, Fardipur and BADC farm, kashimpur, Gazipur whereas the lowest populations were recorded in Farmer’s field Bogra.
