Tomato Wilt

Besides its role during fermentation process, yeast also has potential as biological agent because of its antagonistics characteristic. We have isolated yeast from six different locations based on Phospourus differences. Isolated yeast were then tested its antagonistics ability of Fusarium oxysporum, the pathogen causing tomato wilt disease. This research aims to find out the diversity of yeast found in the tomato rhizosphere in six different contents of phosphorus locations and to know its antagonistics ability against the pathogenic. F. oxysporum. This research was conducted in the Laboratory of Mycology, Department of Pests and Diseases, Faculty of Agriculture, Brawijaya University, Malang and in the Chemistry Laboratory, Institut Teknologi 10 Nopember Surabaya, started from January up to September 2015. Yeasts have been isolated from tomato’s rhizosphere of 6 different locations around East Java proviences. The result showed that yeasts from organic field (Lower P content) were 6 genera. They are Candida sp. 1, Pichia sp. 1, Hansenula sp., Metschnikowia sp. 1, Cryptococcus sp., and Zygosaccharomyces sp. While the yeasts from inorganic field (higher P) were 3 genera. The most potential yeast in controlling F. oxysporum is Pichia sp. 2. Lower P content showed more divers than higher P content. Yeasts from higher soil P content showed more antagonists to control F. oxysporum. Keywords: Phosphor, correlation, yeast, antagonistic, disease, soil

Tomato Wilt

Fusarium wilt disease is a common disease for tomatoes plant which damages plant although it is intensively cultivated. Biological control by microbial antagonism is environmentally friendly compare to the use of fungicide. This research was aimed to study the capability of Bacillus subtilis, Pseudomonas fluorescens, Gliocladium fimbriatum and Trichoderma viridae that are locally specific in controll Fusarium oxysporum f.sp. lycopersici� cause tomato wilt disease. Evaluation of F.o. f.sp. lycopersici� antagonism capability was done by in vitro and in vivo.� In vitro antagonism treatment used the ouble plating treatment on Potato Dextose Agar.� In vivo antagonism treatment was done by gave antagonism agent and F.o. f.sp. lycopersici� together to the earth medium. The result of the study revealed that (1) B. subtilis, G. fimbriatum and T. viridae can pressure the growth and development �F.o. f.sp. lycopersici which cause tomato wilt disease both in vitro and in vivo, (2) In vitro the average of the prevented pathogen growth was as follow: B. subtilis (55.52%), G. fimbriatum (36.77%) and� T. viridae (35.87%), (3) In vivo treatment by the earth medium was not significantly different, and (4) In vivo the ability of prevent disease intensity was as follow : B. subtilis (62.35%), G. fimbriatum (49.95%) and� T. viridae (49.95%).
