Abstract/ Executive Summary:

The experiment was carried out following standard randomized complete block design at the rate of three replications with eighteen new fungicides on BARI Tomato 14 variety. New fungicides significantly enhanced plant height (Magvit 80 WP: 57.44 cm), number of branches (Wonderful 80 WP: 11.67), number of fruit branches (Gunzim & Provax: 10.33), number of fruits (Provax: 40.33) and weight of fruits (Provax: 1209.90 g). The lowest wilt incidence and highest plant survival were recorded in Provax which was statistically similar to Gunzim, Ranazim 50 WP, T. Bendazim, One Sighn, Larkzim 50 WP, Descozim, Biozim 50 WP, Rexizim 50 WP, Sarazim and Rajvit. The highest incidence and the lowest plant survival were recorded in untreated control which was not statistically similar to other fungicides. Provax treated plots gave the highest (39.31 t/ha) yield, which was statistically identical to Gunzim, Ranazim 50 WP, T. Zeb, T. Bendazim, One Sighn, Larkzim 50 WP, Descozim, Biozim 50 WP, Rexizim 50 WP, Sarazim and Rajvit and untreated control gave the lowest yield which was not statistically identical to other fungicides.

Location: Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh

Start Date: 01-08-2011

End Date: 30-04-2012

Program Area: Crop-Soil-Water Management

Commodity: Fungal Disease

Objectives:

To evaluate the effect of new fungicides on wilt incidence and yield of tomato.

Methodology:

Host plant and field area: Tomatoes plants are highly susceptible to fungal diseases were grown in the field of Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh. BARI Tomato 14 variety was used as test plant which was brought from local market. The experimental land was well ploughed and properly leveled before bed preparation. Weeds and stubbles were removed from the field. Cow dung @ 10 t/ha, Urea @550 kg/ha, TSP @ 450 kg/ha and MP @ 250 kg/ha were applied (Sanogo et al., 2003).

Field experiment: The experiment was carried out following randomized complete block design with three replications. Total of eighteen new fungicides were selected for the experiment and study were designed according to the standard alignments. The new fungicides are depicted in table 1. The treatments were applied in pits of tomato plant ten days after crop plantation. Size of the plots was 2.0 m × 1.2 m and plant spacing was 60 cm × 50 cm. Fusariam inoculum was mixed with soil before two weeks of plantation of tomatoes for establishment of fungi. Intercultural operations were done as per needed and to maintain the normal hygienic condition of crop in the field. Wilt incidence, number of healthy plant, plant height, number of branches/plant, number of fruit branches/plant, number of fruits/plant, weight of fruits/ plant yield (t/ha) were recorded (Goldberg 2010).

Statistical analysis: The disease of tomato field percentage of infected plants and percentage of damaged plants was recorded by adopting the grading formula. The percentage of infected and damage plants were calculated by the formula: The recorded data were analyzed statistically to find out the level of significance and the variations among the respective data were compared following Duncan’s New Multiple Range Test (DMRT) according to standard data.

Achievement/Findings:

The present investigation revealed the efficiency of the Provax which gave the highest (39.31 t/ha) with lowest wilt incidence and highest plant survival. Gunzim, Ranazim 50 WP, T. Bendazim, One Sighn, Larkzim 50 WP, Descozim, Biozim 50 WP, Rexizim 50 WP, Sarazim and Rajvit are also performed better for controlling Fusarium wilt of tomato. Moreover, the activity of the fungicides was effective and successfully controlled the fusarium wilt of tomato. Overall, our findings have provided the basis for controlling the fusarium wilt of tomato to untangle the decreased yield of tomato.
