Abstract/ Executive Summary:

Two experiments were carried out at the Bangladesh Institute of Nuclear Agriculture (BINA) farm, Mymensingh using 4 varieties of tomato (including 2 tomato varieties of BINA) to evaluate the efficacy of growing seasons and find out the optimum transplanting date in reducing the incidence and severity of fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici during summer and winter seasons of 2008-09. Disease incidence and severity of the diseases were comparatively lower in the winter season than the summer season. The lower disease incidence and severity were recorded in Binatomato-3 and BARl Tomato-5. A susceptible variety Pusaruby, transplanted on 1 and 16 November had remarkably less percent wilted plants by fusarium wilt than the plants planted on 16th September to October.

Keywords: F. oxysporum, lycopersici, Tomato, Season, Transplanting date

Location: Bangladesh Institute of Nuclear Agriculture (BINA) , Mymensingh

Start Date: 00-09-2008

End Date: 00-03-2009

Program Area: Crop-Soil-Water Management

Commodity: Tomato

Objectives:

To determine the effect of growing season and transplanting time on disease incidence and severity of fusarium wilt of tomato.

Methodology:

Tomato plants were transplanted on two subsequent growing seasons, summer and winter in the field of Bangladesh Institute of Nuclear Agriculture (BINA) , Mymensingh. Seeds were sown on 15 March and 15 October, 2008 to determine the effect of seasons on the incidence and severity of the disease. The experiment was conducted in a 2 factors randomized complete block design with three replications. The factors were (i) seasons (summer and winter) and (ii) varieties (four varieties such as; Binatomato-2, Binatomato- 3, BARI Tomato-4 and BARI Tomato-5). Thirty day-old seedlings were transplanted with a spacing of 50 ern. between rows and plants. Twelve healthy seedlings of each variety plot" were inoculated by soil drenching method with conidial suspension @ 10⁷ conidia ml^-1 of 7 day-old culture of F. oxysporum f. sp. lycopersici. Fertilizers were applied at recommended doses. Recommended cultural practices were followed. Wilting of plants was recorded regularly. Disease severity was computed by adopting (0-4) scale. Percent disease index was evaluated using the following formulae. Percent disease index (PDI) =(Sum of total scores/Maximum grade x Total number of plant assessed) X100. The experiment was set up during the winter season i.e. from September 2008 to March 2009. Tomato plants were transplanted on five different dates starting from 16 September at 15 days interval. The experiment was carried out in a randomized complete block design with 3 replications. Tomato seedlings of susceptible variety Pusaruby were transplanted. The spacing between line and plant were 50 em apart. Seeds/ plants were not given any insecticidal and fungicidal treatments. Method of inoculation, inter cultural operation and method of data recording were the same as described earlier.

Achievement/Findings:

Between the two seasons, disease incidence and severity of fusarium wilt of tomato were comparatively minimum in the winter season than the summer season. Tomato plants transplanted on the 1 st and 16 November had remarkably less percent wilted plants of fusarium wilt than the plants transplanted on 16 September to October. Therefore, in Mymensingh late transplanting (November 16) of tomato is suitable for farmers against the disease.
