Abstract/ Executive Summary:

Experiments were conducted in different locations the field of Bangladesh Institute of Nuclear Agriculture, namely Mymensingh, Ishurdi, Rangpur and Comilla during the Rabi season. To develop an eco-friendly management practice for fusarium wilt of tomato, experiments were done for two consecutive years, 2009-10 and 2010-11. The treatments were: T₁= Seed treatment with hot water, T₂= Soil application of Trichoderma harzianum, T₃= Soil amendment with Mustard Oil Cake (MOC), T₄= Soil amendment with rice husk, T₅= Integration of T₁, T₂, T₃ and T₄, and T₆= Control. All the treatments significantly reduced disease incidence of fusarium wilt. Integration management is more effective than the application of a single treatment in management of fusarium wilt of tomato.

Keywords: Eco-friendly management, Fusarium oxysporum, Tomato

Location: BINA, Mymensingh and BINA substation at Ishurdi, Rangpur and Comilla

Start Date: 16-10-2009

End Date: 24-02-2011

Program Area: Pest Management

Commodity: Tomato

Objectives:

The present study was undertaken to develop an effective and eco-friendly management practice for fusarium wilt (Fusarium oxysporum f. sp. lycopersici) of tomato.

Methodology:

Experiments were conducted in different field stations of Bangladesh Institute of Nuclear Agriculture (BINA) at Mymensingh, Ishurdi, Rangpur, Comilla during the Rabi season of two consecutive years, viz. 2009-10 and 2010-11. The treatments were: T₁= Seed treatment with hot water, T₂= Soil application of Trichoderma harzianum, T₃= Soil amendment with Mustard Oil Cake (MOC), T₄= Soil amendment with rice husk, T₅= Integration of T₁, T₂, T₃ and T₄, and T₆=Control. The experiments were laid out in Randomized Complete Block Design with three replications. The unit plot size was 2m x 2m. Line to line and plant to plant spacing was 50 cm. The variety Pusharubi (susceptible to disease) was used in the experiment. Apparently healthy seedlings of 21 days old were transplanted in the field. Mustard oil cake was decomposed in water for five days and was applied in the soil @ 300 kg ha^-1 before transplanting. Rice husk was applied @ 300 kg ha^-1 during land preparation. Seeds were treated with hot water (50 ⁰C) for 30 minutes. An isolate of T. harzianum (coded as Isolate 038) collected from the Plant Pathology Division of Bangladesh Institute of Nuclear Agriculture was used in the experiment. T. harzianum was mass cultured on chickpea bran and was applied in rows before three days of transplanting. Experiments were conducted in the soil naturally infested with F. oxysporum. Disease incidence was recorded at 40, 55 and 75 days after transplanting.

Achievement/Findings:

Integration management is more effective than the application of a single treatment in management of fusarium wilt of tomato. The findings of the experiment helps in non chemical management of fusarium wilt of tomato. Development of eco-friendly management of the disease supports the sustainability of the environment.
