Endophytic Bacteria from Tobacco Plant as Biocontrol Agent of Meloidogyne spp.Soilborne disease on tobacco plants caused by fungal and bacterial infection in association with root-knot nematode (Meloidogyne spp.) may cause significant yield loss. Endophytic bacteria have been recognized as biological control agent for Meloidogyne spp. as well as plant promoting growth agent. Research was conducted to evaluate endophytic bacteria isolated from tobacco plants as biological control agent for Meloidogyne spp. infecting tobacco. A total of 215 isolates of endophytic bacteria were isolated from root of two tobacco varieties, Kemloko and Prancak 95. Biosafety screening showed that 80 isolates (37%) and 7 isolates (8%) gave negative reaction on hypersensitivity test and hemolysis test, respectively. Seven isolates i.e. TPT3.10, TPT2.1, TK3n8, TK2t21, TK2n8, TK3n1 and TK2t11 were able to promote plant growth and increase the mortality of juvenile Meloidogyne spp. Physiological characterization of endophytic bacteria showed that most of the isolates were able to produce protease enzyme, phosphate, nitrogen and HCN. The same isolates were also able to suppress the number of galls from 80.09% up to 93.82%. Two isolates, TPT3.10 and TK2n8, are considered having the best suppression on root gall formation.

Detection and Identification of Ditylenchus dipsaci from Imported Garlic BulbsImportation rate of garlic (Allium sativum) increased significantly in Indonesia lately. This situation may lead to the introduction and spread of quarantine pests, one of them is bulbborne nematode Ditylenchus dipsaci. This research is aimed to detect and identify the presence of D. dipsaci on imported garlic bulb from China. Samples of garlic bulbs were taken from imported garlic through Tanjung Priok Sea Port, North Jakarta, within importation period from August to December 2017. Nematode extraction was performed by modified Baermann funnel method. Nematode identification was carried out based on the D. dipsaci key morphological characters and morphometry according to de Man formula. This nematode was successfully detected from 20% of garlic bulbs samples based on morphological characteristics, i.e. slender body shape, body length between 0.56 until 1 mm, well-defined stylet (10-13 mm in length), posterior valve between oesophagus and intestine is not overlapping, median bulb obvious with oval shape, and the tail was conoid with a pointed terminus. The findings of D. dipsaci is an important fact because these nematodes have the potential to cause damage to plants in the field.

Identity of Botrytis Species on Horticultural Crops In West Java, IndonesiaBotrytis species are economically important pathogens with a very broad host range including more than 200 horticultural crops. The identity of these fungus found in Indonesia has not been investigated and need to be reconfirmed due to the species variations of Botrytis found worldwide. The aims of this research were to identify Botrytis species infecting crops in West Java based on its morphology and molecular characteristics, as well as its pathogenicity traits. Based on morphological characters, all 25 isolates found were identified as B. cinerea. ITS-based sequences of the 8 isolates showed 96-100% similarity to reported B. cinerea in GenBank. The phylogenetic analysis confirmed that all collected B. cinerea were grouped in the same cluster with Australia, Netherlands, and other Asian region isolates. Pathogenicity tests using strawberry fruits demonstrated that all isolates were pathogenic as indicated by grey mold symptom development; the isolates from orchid showed the highest virulence. This research is the first report confirming Botrytis cinerea identity based on morphology and molecular methods in Indonesia, and also confirmed B. cinerea as the only species of Botrytis found in West Java.

Incidence of Viruses and Fungi on True Shallot Seed and Shallot Bulb Shallot is an important vegetable in Indonesia. Shallot farmers generally use bulbs as planting material even though there is an option to use true shallot seed (TSS). One important criteria for a good seed quality as planting material is pathogen free. Research was conducted to detect and identify viruses and fungi from TSS and shallot seed bulbs cultivars Bima, Bauji, Thailand, and Tuk-Tuk. Virus detection was carried out by DIBA (dot immunobinding assay) method using specific antiserum to OYDV, SLV, SYSV, and GCLV. Detection and identification of fungi was carried out by blotter test method and polymerase chain reaction. Infection of OYDV, GCLV, SYSV, and SLV were only detected in shallot bulbs with infection rates ranging from 66% to 100%. Four species of fungi were detected in TSS and bulbs, i.e. Aspergillus niger, A.flavus, F. solani, and Rhizopus sp; whereas F.oxysporum was only found in bulbs. All isolates of F. oxysporum was pathogenic and cause disease incidence up to 55%. Pathogenic isolate of F. oxysporum had 100% homology to those isolate from China and USA on the spesies level and 91.2% to those isolate from India and USA to the forma spesies level.

Trichoderma and Gliocladium for Controling Fusarium Root Rot Disease of Oil Palm SeedlingsFusarium spp. have been reported as the causal agent of common spear rot and crown rot diseases on oil palm. An effective strategy to control these diseases is not available yet. This research was aimed to find biocontrol agents for effective control of crown rot disease on oil palm seedlings caused by Fusarium spp. The experiment consisted of 3 parts i.e. pathogenicity test of 3 isolates of Fusarium, identification and in vitro test of biocontrol agents, and in planta test of biocontrol agents against Fusarium spp. In vitro test was done through dual culture test and test for volatile compound produced by the biocontrol agents. In planta test was conducted through inoculation of Fusarium spp. into oil palm seedlings growing on medium containing selected biocontrol agents i.e. Trichoderma harzianum, T. virens, T. inhamatum, and Gliocladium fimbriatum. In vitro test showed that Gliocladium fimbriatum 1 and 2 were inhibited effectively the growth of Fusarium spp. on the dual culture test, whereas T. harzianum Gadingrejo 2 was inhibited effectively the growth of Fusarium spp. on volatile compound test. The application of biocontrol agents was effective to protect oil palm seedlings from Fusarium spp. infection.
