Vascular streak dieback (VSD) symptoms was reported recently in several cacao plantations in West Sumatera. Disease incidence reached 58.82–100% with disease intensity of 24.29–44.71%. In some cases, dead plant was also found. Fungal isolation was performed to identify the agents associated with VSD. Plant samples showing VSD symptoms was collected from 3 locations of cacao production center in West Sumatera, i.e. Limapuluh Kota regency, Padang Pariaman regency, and Padang city. Small pieces of leaf and twig were plated on water agar and potato dextrose agar medium for fungal isolation. Morphology of hifa, basidiocarp, and basidiospora observed from fungi colonies indicated the presence of Ceratobasidium theobromae on infected plant samples. This is the first report on the association of C. theobromae on cacao in West Sumatera.

White root disease caused by Rigidoporus microporus is an important disease of rubber tree and is very difficult to control. The ability of some herbaceous plant species to suppress inoculum potential and infection of R. microporus was studied in a pot trial. Nine species of herbaceous plants were examined, i.e. arrowroot (Marantha arundinacea), java curcumin (Curcuma xanthorrhiza), sansevieria (Sansevieria fasciata), Mallaca galangal (Alpinia malaccensis), greater galangal (Alpinia galanga), Indian shot (Canna indica), curcumin (Curcuma longa), wild taro (Colocasia esculenta), and water yam (Dioscorea alata). Pathogen’s inocula as mycelial colonizing rubber wood sticks were buried for 90 days in soil planted with tested plants. The results showed that formation of R. microporus rhizomorph in the soil was lower in pots planted with arrowroot, java cucurmin, sansevieria, Indian shot, and wild taro. All herbaceous plants, except sansevieria, caused suppression of inoculum viability and rhizomorph development. Further observation showed no colonization of rhizomorph nor necrosis of the root was found, except on Mallaca galangal and sansevieria.

Endophytic bacteria have been reported to produce metabolite as antifungal compound. This study was aimed to obtain endophytic bacteria which are able to produce metabolite to control Fusarium sp., a potential seedborne fungi on maize. Endophytic bacteria were screened by hypersensitive test on tobacco leaves and antagonistic test. Endophytic bacteria isolates with high growth inhibitor activity were selected and examined for their metabolite compound. Thre isolates, i.e. Lactobacillus sp. isolate EF14III, Pseudomonas sp. isolate ER1I, dan Aeromonas sp. isolate ER10I has the potential to inhibit Fusarium sp.. Metabolite compound of Pseudomonas sp. isolates ER1I was able to decrease the infection Fusarium sp. by 65.0% in blotter test and decreased infection of Fusarium sp. up to 59.5% and 60.5% in growing on test using water agar and sterile soil, respectively. Cyclohexanone with concentration of 9.68% produced by Pseudomonas sp. isolat ERI1 may play a role as antifungal compound.

Arbuscular mycorrhizal fungi (AMF) is known to improve the growth of shallot (Allium cepa var. aggregatum) and strengthen the resistance of plants toward disease infection. This research aimed to find out the roles of AMF in suppressing the development of purple blotch disease caused by Alternaria sp. on shallot in Caturtunggal, Sleman, Yogyakarta. Inoculation of AMF either on fertilization of N, P, K or without fertilization treatment resulted on higher plant height and number of leaves compared to those without AMF inoculation. The plant inoculated with AMF had lower purple blotch disease intensity and disease progression than control and fungicide treatment. The result showed that AMF, in addition to act as the bio-fertilizer, is a potential to be a biocontrol agent.

Huanglongbing also known in Indonesia as citrus vein phloem degeneration (CVPD) is a devastating disease in citrus plantation worldwide, especially in Asia, Africa, and America. In Asian countries including Indonesia, Candidatus Liberibacter asiaticus (CLas) has been confirmed as the causal agent of huanglongbing disease on citrus. Distribution of CLas in Indonesia has been reported in West Borneo, East Nusa Tenggara, Bali, Yogyakarta, Central Java and East Java. The purpose of this study was to detect CLas in several Indonesia’s citrus plantations that has not and has been reported previously and to study its genetic diversity and their relationship. DNA of plant samples, i.e. citrus leaves, was extracted using CTAB method and CLas was amplified using PCR with the A2/J5 primer pair. DNA amplification results showed that infection of CLas was positively detected from samples from Bogor and Cibodas (West Java), Tuban and Jember (East Java), as well as Katung, Bayung Gede, Kerta, and Pancasari (Bali). Alignment of nucleotide sequences from positive samples showed that their ribosomal protein β-operon has high similiarity to that of CLas OK901 originated from Okinawa (Japan). Isolates of CLas originated from Bogor, Cibodas, Tuban, Jember, and Katung have been known to be identical to other CLas of Indonesian origins reported earlier. Isolates of CLas originated from Bayung Gede, Pancasari, and Kerta have single nucleotide polymorphisms at 6 points of bases of the 539 total bases compared in their conservative regions, although only 3 of the 6 bases could affect their amino acid sequences.

Stem rot or foot rot disease caused by Phytophthora capsici is known as an important constraint on pepper cultivation. Research was conducted to determine the effect of arbuskula mycorhizal fungi (AMF) on incidence of foot rot disease of pepper seedlings. The experiment was done in the net house and arranged using completed randomized design with 6 treatments, i.e. (1) soil infested by P. capsici (TPC) as negative control treatment, (2) sterilized soil (TS) as positive control treatment, (3) TPC with 5 g of AMF, (4) TPC with 10 g AMF, (5) TPC with 15 g AMF, and (6) TPC with 20 g AMF. Observation involved plant height, number of shoots, disease incidence, the percentage of AMF infection on the roots of pepper plants, and pepper plants dependence on AMF. The results showed that the application of AMF at a dose of 20 g per 10 kg of soil effectively suppressed incidence of foot rot disease and improve plant growth

Virus infection on shallots may cause mosaic of leaves and plant dwarf. It is very important to know the identity of the virus as a requirement in determining viral disease management strategy. The research is subjected to identify seed- transmitted viruses from shallot bulbs. Detection of virus from bulb was conducted by growing on test, followed by mechanical inoculation on shallot cultivar Biru Bantul, Chenopodium amaranticolor, and Nicotiana tabacum and morphological observation of virus particle by electron microscope. About 2 weeks after inoculation symptoms was observed, i.e. mosaic and dwarf on shallot cultivar Biru Bantul, local necrotic on C. amaranticolor, but symptomless on N. tabacum. Filamentous particles of 650 nm and 800 nm in length was observed under electron microscope from plants with mosaic and dwarfing symptom, respectively. This indicated the presence of 2 different seed-transmitted viruses on infected shallots. Two species of shallot viruses, i.e. Shallot latent carlavirus (SLV) and Onion yellow dwarf potyvirus (OYDV) was most likely the main seedborne viruses on shallot bulb. Identification based on nucleic acid and protein sequence analysis is necessary for further confirmation

Xanthomonas oryzae pv.oryzae is a casual agent of bacterial leaf blight disease (BLB) of rice. The disease can infect every phases of plant growth and can reduce rice production. In the previous study we have isolated nonpathogenic phyllosphere bacteria against X. oryzae pv.oryzae. For further study, in the present work we developed the formulation of the phyllosphere bacteria and tested their effectiveness against BLB in greenhouse trials. Out of three alternative medium used in culturing bacterial cell biomass, it was revealed that potato broth served as the best medium in comparison with skim milk molasses and bran extract. Formulation of phyllosphere bacteria was conducted by using of talc as main carrier, i.e. approximately 109 cfu g-1of main carrier. Application of the formula on rice leaves indicated that BFV 60, BFF 69, BFR 203 and BFR 153 were the best formula for controlling BLB and were able to reduce disease incidence up to 40.73%, 39.72%, 39.26%, and 28.07%, respectively

Bacterial leaf blight caused by Xanthomonas oryzae pv. oryzae is one of the major problems in rice production in Indonesia. One of the control measures for the disease is by the utilization of endophytic bacteria. This study was aimed to determine the ability of endophytic bacteria isolated from the roots, stems and leaves of rice in inducing plant resistance to bacterial leaf blight on rice. Screening of endophytic bacteria showed that 370 isolates have good viability and have different colony morphology. Among them, 7 isolates were able to induce resistance and 1 isolate was able to promote the growth of rice in the nursery. However, only 8 isolates did not cause hypersensitive reaction on tobacco plants. The selected isolates of endophytic bacteria were further examined for their ability to induce resistance of rice in greenhouse experiments. Observation involved several variables, i.e. PR1 and PBZ1 gene expression, peroxidase enzyme activity, incubation period, and disease progression. Seven isolates of endophytic bacteria were able to induce PR1 and PBZ1 gene expression, 4 isolates were able to increase peroxide enzyme activity, 4 isolates could prolong the incubation period, and 2 isolates can inhibit the development of disease. However, only EB4 451 isolate was consistently able to induce PR1 and PBZ1 gene expression, increased peroxide enzyme activity, prolonged incubation period, and suppressed the progression of the disease. The EB4 451 isolate was identified based on nucleotide sequence as Bacillus subtilis.
