- The purpose of research is to understand the potency of Pseudomonas sp. origin of paddy rooting endophtyic against leaf spot disease (Curvukaria sp.) using in vitro method. The research is conducted in Agroekoteknologi, Faculty of Agriculture, Sultan Ageng Tirtayasa University Laboratoy between January-April 2016. The research conducted using one factor trial that arranged inside Completely Randomized Design with three repetition. The treatment consist of 9 Pseudomonas sp. Isolates that obtained from paddy rooting, based on the result of early screening and 1 control as comparison. Research result shows that the clear zone diameter in every Pseudomonas sp. Isolate bacteria is in fact different. Pseudomonas sp. Bacteria has a different shape of colony. Endophtyic bacteria which include Pseudomonas sp. has different attribute and character. Some of them are pathogenic (cause of disease), and some of them are not. The identification result using KOH 3% shows that Pseudomonas sp. Bacteria has negative gram trait. Biggest obstructing potency are located in BEP 3 (38,30%), BEP 5 (24,78%), BEP 7 (38,28%), BEP 14 (43,09%), BEP 18 (25,32%), and BEP 19 (24,30%). The results showed that the bacteria Pseudomonas sp. on this research is potential on controlling leaf spot disease in paddy.
