Rhoeo discolor has been known to have a good adaptation to various environmental conditions. This character might be due to mutualistic association with endophytic bacteria. The objective of this study was to isolate endophytic bacteria from roots of R. discolor and to evaluate their potency as biocontrol agents and plant growth promoters. The methods to isolate endophytic bacteria involved the following methods, sterilization of root surface, grinding of root tissues, dilution, and plating in the medium tryptone soya agar (TSA). A total of 21 isolates of endophytic bacteria were isolated from the roots of R. discolor. Based on hypersensitivity test on tobacco leaves, 19 isolates showed negative reaction (no necrosis symptom) and only 2 isolates showed positive reaction (necrosis was developed). The results on biocontrol and growth promoters assay showed that 7 isolates were able to inhibit the growth of Fusarium oxysporum under in vitro test and 12 isolates were able to increase the growth of rice seedlings.

A method for identification of the causal bacteria of citrus vein phloem degeneration (CVPD) based on polymerase chain reaction (PCR) technique using template DNA extracted from leaf midrib of citrus has been implemented routinely. The method has not been validated, therefore it is necessary to validate the method to confirm that the method fit for its intended use. Leaf samples showing chlorotic symptom was obtained from Bogor and Bekasi, West Java and used for test samples. These samples was differentiated into 2 groups, i.e. leaf midrib and leaf mesophyll. Validation test involved homogenicity, and reproducibility test; each test was replicated 2 times. The test showed that using leaf midrib gave better result for detection of bacteria causing CVPD disease than using leaf mesophyll. Therefore, this method is recommended as routine detection method for bacteria causing CVPD disease.

Plant-parasitic nematodes are important pests on carrot (Daucus carota) in Malino Highland. This research aimed to identify plant-parasitic nematodes on carrot. The identification was carried out based on the morphological and morphometric characters of second-stage juveniles that were extracted from soil samples. Nematodes were extracted using the flotation-centrifugation technique. Morphometric measurement included body length, stylet length, esophagus length from the basal knob to the esophagus end, tail length from the posterior end to the anus, anterior diameter, maximum body diameter, and posterior diameter. Three genera of plant-parasitic nematodes were identified as Meloidogyne, Rotylenchulus, and Pratylenchus.

In Indonesia, high yield losses due to post-harvest diseases are often difficult to measure because research focusing on such matter are still limited. This study aimed to determine the genera of fungi that cause rot on postharvest fruit, which can be used as a basis to determine the important pathogens in the current post-harvest commodities and for further disease management. The method used is sample collection, single spore isolation, microscopic observation and identification of fungal genera. Colletotrichum sp. was sucessfuly isolated from antrachnose of papaya. Pestalotia sp. was found in the fruit rot of avocado and star fruit. Lasiodiplodia sp. was found in mango, while Pestalotia sp. and Lasiodiplodia sp. was found in both sapodilla and banana. Alternaria sp. was found in the fruit rot of pears and apples. Aspergillus sp. was found in grapes, and Fusarium sp. was isolated from pineapple fruit rot.

Seed quality is very critical in agricultural production, especially to gain high yield and reduce disease problems in the field. New diseases or pathogens is potentially entering a country through seed movement by import activity. This study aimed to detect and identify seed-borne fungi from Brassicaceae seeds imported from the United States and Malaysia. Seeds were incubated on 5 sheets of wet blotting paper at a temperature of 27–30 °C for 14 days following surface sterilization. Each fungus that grows on the seed was isolated on potato dextrose agar and malt extract agar for further morphological identification. The three fungi most commonly found either on the seed with or without surface-sterilization were Aspergillus flavus, Curvularia lunata and A. niger. All of the fungi were a potential pathogen in the family Brassicaceae seeds and seedlings. Important pathogen in Brassicaceae crops, i.e. Phoma lingam was also found in small amounts and only on white pak choy seeds.
