Abstract

Antraknosa merupakan penyakit penting pada tanaman cabai yang dapat menyebabkan kerugian ekonomi cukup besar. Khamir merupakan salah satu mikroba yang telah diketahui berpotensi sebagai agens antagonis pada berbagai produk pascapanen. Penelitian ini bertujuan untuk mendapatkan isolat-isolat khamir epifit yang berpotensi sebagai agens antagonis penyakit antraknosa pada cabai. Penelitian dilaksanakan di Laboratorium Mikologi Tumbuhan dan Kebun Percobaan Institut Pertanian Bogor, dari bulan April sampai Desember 2013. Khamir epifit diisolasi dari daun dan buah cabai merah yang diperoleh dari pertanaman cabai di Rancabango dan Panjiwangi (Kabupaten Garut) dan Dramaga (Kabupaten Bogor). Patogen penyebab antraknosa yaitu Colletotrichum acutatum diisolasi dari buah cabai bergejala dari pertanaman cabai di Panjiwangi. Khamir hasil isolasi diuji patogenisitasnya pada benih dan buah cabai. Khamir nonpatogenik diseleksi potensi antagonismenya terhadap  penyebab penyakit antraknosa. Diperoleh 43 isolat khamir epifit, semua isolat bersifat nonpatogenik berdasarkan hasil uji patogenisitas. Seleksi potensi antagonisme isolat khamir epifit menghasilkan 23 isolat yang berpotensi sebagai agens antagonis C. acutatum. Empat belas isolat  khamir epifit menyebabkan penghambatan penyakit antraknosa lebih besar dibandingkan mankozeb.

Abstract

The incidence of mosaic disease on vegetable crops in Indonesia has been reported recently. The disease is caused by TuMV which is considered as a new and important virus on caisin and turnip in Indonesia. Field survey has been conducted to determine disease incidence in vegetable growing areas. Symptom variability and host range of TuMV was further studied through mechanical inoculation to cruciferae and solanaceae plants. Observation during field survey has proved that TuMV has infected caisin and turnip in Java and Bali. The highest intensity of mosaic disease i.e. 63,3% occurs in Tumpangan-Malang, followed by Denpasar Selatan and Bandungan-Semarang with the intensity of 30,5% and 19,0% respectively. TuMV infection causes different types of symptoms, such as: wrinkled leaf, blistered leaf, vein banding, vein clearing, leaf distortion and proliferation. The host range of TuMV involves those plants belong to cruciferae (cabbage, broccoli, caisin, turnip, cauliflower, chinese cabbage, pak coy); solanaceae (N. tabacum, N. benthamiana, N. glutinosa); and chenopodiaceae (C. amaranticolor). Furthermore, N. glutinosa can be used as differential host for TuMV isolates.

Abstract

Pepper yellow leaf culr disease has been widely spreading in Indonesia, especially in Special Province of Yogyakarta and Central Java since 2000. The disease is difficult to control because its fast spreading over in the field by the vector. To prevent epidemic of the disease, early detection method of the causal agent is needed. The aim of the research was to detect the causal agent of the pepper yellow leaf curl disease by isolating the DNA genome. Using the Guanidine-alkaline method, two specific fragments of the DNA were produced approximately at 2600 bp and 1600 bp. The DNA fragments were similar with the DNA genome of Begomovirus. The method applied in this study is faster and easier for early detection of the Begomovirus in infected crop than detection by the Polymerase chain reaction (PCR).

Abstract

Incidence of geminivirus infection has been caused severe losses on various economically important crops. This losses may cause by single infection or mix infection of several strain of geminiviruses. In this experiment we used two strain of geminiviruses, geminivirus infecting chillipepper from Segunung, West Java and geminivirus infecting tomato from Lembang, West Java (GVToL), to study the effect of geminivirus mix infection on the symptom expression and the capability of each strain to multiply in the host cell. Coefficient of dissimilarity between this two strain of geminiviruses is 7.5. When the two strain of geminiviruses was inoculated together to tomato plants by insect vector; Bemisia tabaci, the symptoms on infected plants is slightly different but less severe than those on plants inoculated with each strain separately. Detection with polymerase chain reaction (PCR) followed by restriction enzyme digest of PCR product revealed that GVToL multiply better in the infected host cell.

Abstract

Virus identification based on the serological assay has been widely applied as a tool for plant virus detection. The aims of this research is to produce antiserum of the Pepper yellow leaf curl virus by rabbit immunization using purified gcminivirus of Segunung isolate. Identification of the virus was done by using modified I-ELISA and DIBA methods and also by using western blott. I-ELISA and DIBA methods were able to detect the geminivirus in the infected samples. The reactivity of antiserum was found to be similar amontI pepper isolates from different location (Segunung, Yogyakarta, Cugenang, and Lembang) ana those from different hosts (pepper, tobacco, tomato and Ageratum conyzoides) The antiserum could also be used for detection and identification of the Pepper yellow leaf curl virus in its vector. A single insect vector is sufficient for the detection of virus properly. The detection of geminivirus in its vector is very useful because it can be used to study the epidemic of the disease in the field. The I-ELISA and DIBA methods are very useful as tools for detecting the geminivirus. The methods are very easy to be carried out, fastly, and need only a minimum cost on operation. Geminivirus could also be identified by western blott analysis.

Abstract

Two aphid species, Myzus persicae (Sulzer), and Aphis gossypii (Glover) and the five potato varieties (Alpha, Bintje, Berthaultii, Granola and Premiere) were used in the experiments to study the relationship between insect vector dispersal and dissemination of disease caused by potato virus Y (PVY). The results showed that M. persicae could cause time for the appearance of first symptom two to four time faster than A. gossypii . Although statistical analysis (anova) in general showed that disease incidence is not significantly different for each treatment. M. persicae caused higher disease incidence than A. gossypii on Bintje (56 and 74 days after planting). M. persicae seems to have better capability to disperse when the plant reach vegetative growth stadia which may result in higher efficiency of transmitting the virus. The relationship between aphid dispersal and dissemination of PVY can be grouped into four categories (1) plant with aphid and showing symptom; (2) plant without aphid but showing symptom; (3) plant with aphid but without symptom; (4) plant without aphid and without symptom.

Abstract

Banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is known as vector of Banana bunchy top virus (BBTV) that threatening production of banana worldwide. It was reported recently that P. nigronervosa and P. caladii is “cryptic species”.  A good and proper identification is necessary to verify the correct species and its status. Research was conducted to identify and to find the host range of banana aphids in Java. Aphid collection was conducted in several locations in West Java, Central Java, and East Java. Eleven morphometric characters were analyzed to assess the morphometric variations among banana aphids. Morphological identification and principle component analysis (PCA) approach were conducted for accurate identification of banana aphids. Two species of aphids were found during the survey in Java, i.e. P. nigronervosa and P. caladii. P. nigronervosa mostly infested bananas (Musa spp.), and a few was found on heliconia (Heliconia sp.) and banana traveler (Ravenala madagascariensis). In contrast, P. caladii generally infested taro (Colocasia esculenta), turmeric (Curcuma longa), costus (Costus sp.), dumbcane (Dieffenbachia sp.), but rarely on bananas.

Abstract

Yellow leaf curl disease of chili pepper caused by Pepper yellow leaf curl virus (PYLCV) has been reported as an important disease in Java and Bali. Disease severity reached 80−100% and it may cause significant yield losses. In order to reduce the negative impact of synthetic insecticides, silica application was evaluated for its potency to suppress the disease. A greenhouse experiment was conducted using randomly block design with 2 factors: PYLCV isolate (Java and Bali) and silica (SiO2) treatment (with and without). Parameters observed were disease symptoms, incubation period, disease incidence and severity, and total silica level. The symptoms of virus infection in Pelita 8 and Seret cultivars were yellow mosaic, leaf curl, green mosaic, dwarf, and cupping upward or downward. A Specific DNA fragment of 912 bp was successfully amplified from 4 samples. Four sequences were obtained and further analysis showed their highest homology, i.e. 96% and 97% with Pepper yellow leaf curl Indonesia virus-Java (PYLCIV-Java) (JX416180) and PYLCIV-KrthAl (LC381274), respectively. Infection by different virus isolates did not affect disease severity significantly. The application of silica was able to delay symptom development and to suppress the severity of the disease in the range of 16.67−30.33%. Silica application on the soil increased the total content of silica in the plants. However, a further experiment is required to understand the mode of action of silica in inducing plant resistance to the pathogen.

Abstract

Epiphytic yeasts have the potency as antagonistic agents against various pathogens of post-harvest products. Anthracnose is a major disease of chilli that causes high economic loss. This research was objected to study the antagonism mechanism of epiphytic yeast isolates that have the antagonistic potency against anthracnose pathogen on chilli (Colletotrichum acutatum). Twenty-two isolates of epiphytic yeasts, isolated from chilli leaves and fruit, were tested. The characterization of the antagonism was carried out by antibiosis, anti-fungus volatile production, and chitinolytic activity tests. The results showed that all tested isolates did not have antibiosis mechanism against C. acutatum. All isolates produced volatile compounds which inhibited the colony growth of C. acutatum. Four isolates showed high relative inhibition rate, i.e. isolates B32DEP (35.68%), B30DEP (37.52%), B23DEP (38.52%), and B29DEP (45.42%). Fourteen isolates showed chitinolytic activities. Three of them had high chitinolytic activities, i.e. B12DEP, B2DEP, and G237DEP.

Abstract

A survey on several cucumber cultivation areas in West Java, Central Java, Yogyakarta, and East Java found many plants showing typical Begomovirus symptoms such as yellow mosaic, cupping, and vein banding. This study was aimed to determine disease frequency, detection and molecular characterization of the causal virus of those symptoms on cucumber in Java. Sampling was conducted by purposive sampling by collecting 50 symptomatic plants from each location in West Java (Indramayu, Subang, and Bogor), Central Java (Brebes and Klaten), Yogyakarta (Kulon Progo), and East Java (Nganjuk, Kediri, and Tulungagung). The detection and disease frequency was determined based on DIBA test using a specific antiserum of Tomato leaf curl New Delhi virus (ToLCNDV) and Squash leaf curl virus (SLCV). The identification of nucleic acid was conducted by PCR using specific primer of ToLCNDV and SLCV, DNA cloning, and sequencing. The results of serological detection showed the disease frequency of ToLCNDV and SLCV ranged from 92.77-100% and 78.33-93.3%, respectively. PCR using specific primer of ToLCNDV successfully amplified the coat protein gene at a size of 600 bp from all samples. Homology nucleotide and amino acid sequences among ToLCNDV Java isolate ranging from 95.6-99.2% and 99.7-100%. ToLCNDV isolates Java had highest nucleotide and amino acid sequences similarity with cucumber isolate from Klaten, Indonesia (AB613825) ranging from 96.1-98.1% and 99.7-100%, and was considered as “Indonesia” strain. SLCV not amplified on all samples by PCR using specific primer, indicating it might not present yet on cucumber in Java.
