Evaluation of Four Isolates of Trichoderma Harzianum Against Fusarium Wilt of Tomato

Dr. Mahbuba Kaniz Hasna
Senior Scientific Officer
Plant pathology Division, Bangladesh Institute of Nuclear AgricultureBAU Campus, Mymensingh

Abstract/ Executive Summary:

Four isolates of T. harzianum collected from Plant Pathology Division of BINA were evaluated against fusarium wilt (Fusarium oxysporum f. sp. lycopersici) of tomato at BINA sub-station farm of Magura and Ishurdi during the winter period of 2010-11.The experiment contained five treatments such as four isolates of Trichoderma (Iso.0029, Iso.0037, Iso.0038 and Iso.0043) and control. The inoculum of T. harzianum was applied in soil @5g/m² at 3 days before transplanting.The incidence of fusarium wilt was recorded at 40, 55 and 75 days after transplanting.The disease incidence ranged from 6.62-27.08% in Magura and 5.38-25.17% in Ishurdi. Among the isolates, Iso.0038 showed better performance in controlling disease compared with control in both locations (6.62% in Magura and 5.38% in Ishurdi).

Keywords: Fusarium wilt, Trichoderma harzianum, Tomato

Location: BINA sub-station farm of Magura and Ishurdi

Start Date: 24-10-2010

End Date: 22-02-2011

Program Area: Pest Management

Commodity: Tomato

Objectives:

To evaluate the efficacy of four isolates of Trichoderma harzianum in controlling fusarium wilt of tomato.

Methodology:

Four isolates of T. harzianum collected from Plant Pathology Division of BINA were evaluated against fusarium wilt (Fusarium oxysporum f. sp. lycopersici) of tomato at BINA sub-station farm of Magura and Ishurdi during the winter period of 2010-11. The experiments were conducted in randomized complete block design with three replications. The experiment contained five treatments such as four isolates of Trichoderma (Iso.0029, Iso.0037, Iso.0038 and Iso.0043) and control. The isolates were tested against the variety, Pusharuby. The unit plot size was 2m x 2m. Seedlings of 25-days old were transplanted. Fertilizer was applied as per recommended dose.No pesticide was applied. Mass inoculum production of T. harzianum was done in chickpea bran. The inoculum of T. harzianum was applied in soil @5g/m2 at 3 days before transplanting. Experiment was conducted in soil naturally infested with Fusarium oxysporum.The incidence of fusarium wilt was recorded at 40, 55 and 75 days after transplanting.

Achievement/Findings:

An isolate of Trichoderma harzianum has better performance in controlling fusarium wilt of tomato. This result helps to develop biological control strategy against the disease. Development of biological control reduces the use of pesticides and thus supports the sustainability of the environment.
