Functional microbes of rhizosphere play important roles in nutrient transformation and controlling disease as well as in supporting plant growth and development. However, there is no study on the role of functional microbes on pineapple productivity. The purpose of this study was to investigate the abundance and diversity of soil functional microbes at different growth phases at two levels of productivity and their correlations to disease incidence. The research process included sampling of pineapple rhizospheric soil from vegetative and generative phases pineapples at low and high plant productivity sites, observations of disease incidence, and isolations of functional microbes. Functional groups of bacteria were Azotobacter, phosphate-solubilizing bacteria, potassium-solubilizing bacteria, antibiotics-producing bacteria, IAA-producing bacteria, and chitinolytic bacteria. The soil sampling method was simple randomized sampling at 6 locations with an area of each location ± 5 ha with a depth of 20 cm. Rhizosphere were taken in plants grown in high productivity area (>60tons/ha) and low productivity area (<60 tons/ha) in vegetative and generative phases. The results showed that potassium-solubilizing bacteria, chitinolytic bacteria, and IAA-producing bacteria were more abundant during the generative phase compared to those during vegetative phase. While Azotobacter, phosphate-solubilizing bacteria, and antibiotic-producing bacteria were more predominant during vegetative phase at various crop productivy. Total density of microbes was higher in soil with high crop productivity than that in soil with low crop productivity. The abundance of chitinolytic bacteria and IAA-producing bacteria had negative correlation with disease caused by Erwinia chrysanthemi and Phytophthora cinnamomi. Keywords: chitinolytic bacteria, growth phase, IAA, pineapple disease

Application of fungicides to control rice diseases potentially have adverse effect on non target organisms including endophytic fungi. Unfortunately, information of fungicide effect on endophytic fungi on rice is still limited. The purpose of this research was to study the diversity and abundance of endophytic fungi on rice plant because of application of synthetic fungicides. There were two treatments in this study: non systemic fungicide (mankozeb) and systemic fungicide (difenoconazole) which were compared to control (without fungicide). Isolation of endophytic fungi and application of fungicides were conducted every week started at aged of 3 to 10 weeks after planting. Variables observed were total segment of rice colonized by endophytic fungi, colonization frequency of endophytic fungi, continued by identification and analysis of the diversity of endophytic fungi. This study showed that there was an increase in colonization of endophytic fungi with an increase of plant ages. The diversity of endophytic fungi was higher in stems than in leaves with the value of H' is 0.00-1.35 and 0.00-0.98 respectively. The most common types of endophytic fungi appear in each isolation of rice segments were Acremonium, Curvularia, Fusarium, Helminthosporium, Nigrospora, Penicillium, and Mucor. Both fungicides do not significantly affect the percentage of colonization and diversity of endophytic fungi. At the beginning of planting (4-6 MST) there was a decrease in the percentage of endophytic fungal colonization in the stem. From the percentage of colonization of each genus of fungi, Nigrospora and Fusarium decreased significantly with difenoconazole on the stem during the vegetative phase. Keywords: colonization, community, difenoconazole, diversity, mancozeb

Sengon (Falcataria moluccana) cultivations still have to face threats from plant diseases. Diseases can be found in nurseries and plantation. Biological agents can be used to control various types of plant diseases and have various advantages. The use of biological agents in forestry plantations must consider the aspects of effectiveness and efficiency. This study aims to examine the effect of various treatment of control technology packages on the incidence of major diseases, and to determine the financial feasibility of various disease control technology packages for sengon in nurseries. The research was conducted through interviews to explore cultivation techniques and production costs. In addition, experiments were carried out on the application of various disease control strategies using commercial formulations of biological agents. The commercial formulations of biological agents used were Rhizomax, Primagrain, Trichowish, Kayabio, Bio-Hara Plus, and fungicide Dithane M-45 80 WP. There were two treatment packages of new technology that have an effect on increasing the growth of sengon at the beginning of growth stage, namely P1 (BioHara Plus and KayaBio) and P2 (Rhizomax and Primagrain) treatments. All treatments of the new technology package had no significant effect on increasing the survival rate and suppressing the incidence and severity of disease in sengon seedlings. All new technology package treatments can generate profits even though the value is smaller when compared to existing technology treatments. All the new technology package treatments have an R/C ratio of more than 1 so that they are feasible to be applied by farmers. Keywords: biological control, feasibility, plant diseases, nurseries, Falcataria moluccana

Wilt disease of watermelon is an important disease in Indonesia, but determination of the causal agent has not been reported yet. Postulat Koch based approach was conducted to determine the pathogen causing wilt of watermelon from Karawang, West Java. Fungi associated with wilt symptoms were isolated from stem and root, then the fungal colonies were identified based on their morphological characters. Pathogenicity tests were performed using soil media and wet paper. Host range study involved other Cucurbitaceae plants, i.e. cucumber, melon and paria. Three species of Fusarium were successfully isolated from plants showing wilt symptom, i.e. F. oxysporum, F. solani, and F. semitectum. The fungus F. oxysporum consistently caused the most severe wilt symptom on watermelon, but developed no symptom on other tested cucurbits. The two fungi, F. solani and F. semitectum, caused necrotic on roots and stem of watermelon followed by wilting of the plant. The symptom was different than those of the initial symptoms from the field. Therefore it concluded that wilt symptom of watermelon is caused by Fusarium oxysporum f.sp. niveum. Key words: Cucurbitaceae, Fusarium oxysporum f.sp. niveum, species identification, wilt

Studies on endophytic bacteria has been increasing recently due to its potency to promote plant growth and induce plant tolerance to pests and diseases. The research was undergone to isolate endophytic bacteria from different varieties of upland rice from various growing regions in Indonesia, followed by evaluation of their biocontrol and plant growth activities. Isolation of endophytic bacteria was based-on surface-sterilized method using alcohol and NaOCl on trypsic soy agar (TSA) media. More than 200 isolates was successfully isolated and the selected isolates were subjected to in vitro assay for their ability to produce antibiotic and promote plant growth. The result showed 41 isolates of endophytic bacteria had antibiosis activity to Rhizoctonia solani, 25 isolates to Pyricularia grisea on potato dextrose agar (PDA) medium and 8 isolates showed antibiosis activity to both R. solani and P. grisea on both PDA and TSA. The result of plant growth test, showed 12 isolates of endophytic bacteria induced the growth of root and shoot of rice plant.This indicated that some of the endophytic bacteria have the potency as biocontrol agents and inducer of plant growth.Key words: endophytic bacteria, Pyricularia grisea, Rhizoctonia solani, upland rice

Severe mosaic symptoms was observed on papaya plants in Meusa village, Kutablang sub district, Bireun district and Lambaro Teunom village, Lembah Seulawah sub district, Aceh Besar district. Systemic mosaic was found in leaves, stem, twig, and fruit. Reverse transcription-polymerase chain reaction (RT-PCR) was conducted to detect the virus causing mosaic symptoms using universal primer for Potyvirus. Amplification of 320 bp DNA fragment was successfully obtained from leaves and fruits bearing severe mosaic symptoms. Nucleotide sequencing was proceeded using the DNA amplicon as the template. Further sequence analysis indicated that Potyvirus isolates from papaya in Aceh show the highest homology (92.7% to 94.7%) with Papaya ringspot virus (PRSV) from Philippines, Thailand, and Indonesia. This is the first report on PRSV infection on papaya in Nanggroe Aceh Darussalam province. Key words: Potyvirus, RT-PCR, sequencing

Endophytic fungi have been reported to have mutual symbiosis with their host. This research aimed to obtain nonpathogenic isolates of endophytic fungi from roots, stems, and branches of chili pepper. Endophytic fungi were isolated on 10% malt extract agar (MEA) after serial surface sterilization of plant parts. The effect of endophytic fungi on the development of chili pepper seeds were tested by growing seeds on media containing endophytic fungi isolate. As many as 138 isolates of endophytic fungi were successfully isolated from chili pepper plants from Garut and Bogor. Based on colony morphology the isolates can be differentiated into 9 morphotypes. Among the total isolates, 13.04% are nonpathogenic. Some of them (7,25%) do not effect seedling significantly compared to control and some isolates (5.79%) caused better seedling growth than control. Endophytic fungi having the potential to promote plant growth was identified as Aspergillus sp., Fusarium sp., Penicillium sp., sterile hyphae 1, 2, and 3.

Anthracnose caused by Colletotrichum gloeosporioides is an important disease in avocado fruit during storage. An effective, cheap, and safe control method is necessary as an alternative to subtitute the use of fungicides in postharvest disease control. This research aimed to identify yeast antagonist from avocados that are effective in controlling anthracnose disease on avocado fruit. Research was started with isolation of C. gloeosporioides and yeast from avocado fruit, followed by in vivo bioassay, antibiosis assay, and chitinolitic activity assay. In vivo bioassay was done by dipping avocado fruit on yeast cell suspension. As many as 23 yeasts isolates was obtained from avocado fruits. Eight yeast isolates (A28, A32, A33, A34, A35, A36, A37, A38) showed very effective for inhibiting anthracnose disease in avocado fruit at concentration of 106 mL-1 and 107 mL-1. However, only four isolates were chosen for further characterization based on morphological and molecular identification. Two species of yeast was identified as Pichia anomala, i.e. isolates A33 and A37 and Candida intermedia, i.e. isolates A35 and A36.
