Abstract

Isolation and identification of mangosteen yellow latex pathogen through Koch’s Postulate application and molecular analysis. The yellow latex disease decreases fruit quality of mangosteen because exogenic latex causes dirty fruit and the endogenic latex makes the bitter fruit taste and does not deserve to be consumed. The causal agent of the disease caused phusilogical disorder so that cells break due to unstability of cell turgor, the drift irrigation treatment was able to decrease the disease of 35.22%, therefore the causal agent could be microbe that promote the yellow latex. This research was aimed to find the yellow latex pathogens with its characteristics. The Koch Postulate was apllied to isolate and proved the microbes associated to the yellow latex and molecular analysis was constructed subsequently to find the microbe species.  The result of the research proved that there were three fungus species as the biotic agent responsible to the disease. The fungus were Verticillium albo-atrum with the highest pathogenecity ( 74.87%), followed by Fusarium oxysporum ( 70.15%), and Pestalotia macrotricha (20.32%).

Abstract

Fusarium wild or wilt disease that attacks banana plants is caused by the pathogenic fungus Fusarium oxysporum f.sp. cubense This disease is difficult to control because it lasts a long time in the soil by forming chlamydospores. Currently, the control of this disease is still using synthetic fungicides, but this method can cause damage to the ecosystem. Biopesticide is one of the environmentally friendly control of plant pathogens because biopesticides use biological agents. The purpose of this study was to export rhizoplan bacteria from banana plant roots which have antifungal activity against F. oxysporum f.sp. cubense. The results showed that rhizoplan bacteria were able to inhibit the growth of Fusarium oxysporum f.sp. cubense fungal colonies on potato dextrose agar (PDA) media with an inhibitory percentage of 90.90% when compared to the control. The results of the bacterial filtrate test of rhizoplan at a concentration of 50% were able to inhibit the growth of the fungus Fusarium oxysporum f.sp. cubense with an inhibitory percentage of 92.72%.
