The effectiveness of fungi Gliocladium fimbriatum and Trichoderma viride to control fusarium wilt disease of tomatoes (Lycopersicum esculentum)

Tomato (Lycopersicum esculentum) is a horticultural commodity with high economic value. However, serious disease management is needed to get good production with better fruit quality. Wilt disease caused by Fusarium is constraining tomato production. This study was aimed to measure the effectiveness the use of Gliocladium fimbriatum and Trichoderma viride to control fusariumwilt disease. This study was conducted in Food Crop and Holticultural Plant Protection Institute of West Papua and Laboratory of Plant Diseases of Agricultural Faculty, Papua University, Manokwari. This study was designed using factorial complete randomized design consisting of two treatment factors and repeated three times. The experiment findings indicated that servo variety was better compared to other tested varieties as indicated by better plant height, low fusarium wilt disease intensity, and higher fruits quantity and weight. Trichoderma and Gliocladium were capable of controlling the development of fusarium wilt disease in tomatoes plant, but the effectiveness of Trichoderma (53.68%) was better controlling the pathogen compared to Gliocladium (48.89%). Interaction between the treatments of Servo variety and fungi Trichoderma resulted in better effect both to lower disease intensity and higher fruits quantity and weight.
