Tujuan penelitian ialah mendapatkan data keanekaragaman secara genetik dan fenotipik isolat bakteri X. campestris pv. campestris, serta mendapatkan data respons resistensi isolat bakteri tersebut terhadap campuran bahan aktif azoksistrobin dan difenokonazol. Penelitian terdiri atas lima tahapan, yaitu (1) pengambilan sampel pada lahan yang terdapat gejala busuk hitam; (2) isolasi bakteri menggunakan teknik penanaman jaringan; (3) seleksi isolat dengan uji sifat Gram, hipersensitif, hidrolisis pati, dan patogenesitas; (4) identifikasi menggunakan primer spesifik dan universal 16S rRNA; dan (5) analisis keanekaragaman genotipe dengan metode RFLP in silico dan keragaman fenotipe dengan mengukur bobot eksopolisakarida. Hasil karakterisasi dan identifikasi secara molekuler diperoleh lima isolat bakteri X. campestris pv. campestris, yaitu CLT01, CDA08, SDA02, SDA22, dan SDA26. Hasil analisis keanekaragaman genotipe menunjukkan bahwa kelima isolat memiliki keanekaragaman berdasarkan pemotongan fragmen DNA gen 16S rRNA, sedangkan keragaman fenotipe ditunjukkan dengan nilai inhibition consentration (IC) yang berbeda-beda. Isolat SDA22 memiliki nilai IC50 paling tinggi dan keanekaragaman secara genetik yang berbeda dibandingkan dengan isolat X. campestris pv. campestris lainnya. Penggunaan pestitida sintetis azoksistrobin dan difenokonazol secara terus-menerus dalam jangka waktu lama dikhawatirkan berdampak pada patogen seperti X. campestris pv. campestris. Oleh karena itu, alternatif pengendalian yang lain diperlukan agar tidak terjadi resistensi pada X. campestris pv. campestris.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42046601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was conducted to examine the effect of biofumigant derived from Brassicaceae plants waste on soil nematode population dynamics. Greenhouse experiment was carried out on 4 types of Brassicaceae plants waste, consisting of leaf waste of radish (Raphanus sativus), broccoli (Brassica oleracea var. italica), cabbage (Brassica oleracea var. capitata), and whole parts kamanilan weed (Roripa indica) in polybags containing 5 L of nematode infested soil. Plant waste was chopped ± 1 cm in size, then as much as 117 g per polybag was mixed in nematode infested soil, doused with water until wet and tightly closed for the biofumigation process for 14 days. At the end of biofumigation step, the polybags were opened for 3-5 days, then 7 day - old cucumber seedlings of var. Roberto 92 were planted and the plants were maintained in greenhouse for up to 8 weeks. Observation of the type and population of soil nematodes was carried out three times, i.e. before treatment, after treatment, and 8 weeks after planting. This experiment was designed in a completely randomized design with 6 treatments and 5 replications. The results of the study showed that the population of free-living nematodes (bacteriovorous nematodes and fungivorous nematodes) was increased in all treatment of Brassicaceae plants waste. On the other hand, there was a significant decrease in the phytonematodes population in the treatment of broccoli leaf waste. All Brassicaceae wastes was able to suppress population of Helicotylenchus sp., Rotylenchulus sp., and Xiphinema sp., significantly. Leaf waste of broccoli leaves showed the highest inhibition value against all phytonematodes genera with inhibition reached 100%.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46437333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agricultural technology 4.0 began to be used for the development of plant disease detection methods. It was reported that there were differences in color and temperature between diseased and healthy plants which could be recorded by a thermal camera. This study aimed to determine the potential of the FLIR One Pro-IOS thermal camera to record differences in color and temperature between viral-infected and healthy chili plants. Chili plants in the greenhouse that were inoculated with Pepper yellow leaf curl virus (PYLCV) experienced an increase in temperature 3 days after inoculation (28.62 ℃) compared to plants that were not inoculated with PYLCV (27.32 ℃). Digital image recording of chili leaf samples from the field showed that plants infected by multiple viruses (Chilli veinal mottle virus, Pepper mottle virus and PYLCV) has higher temperature than those infected with a single virus. The lowest and highest mean temperatures were recorded in plant samples infected with PepMV (17.74 ℃) and mixed infected by PYLCV and ChiVMV (25.68 ℃). Digital images of virus-infected plants tend to show a predominance of bright yellow, while virus-free plants showed a predominance of dark purple. Further analysis confirmed higher digital numbers for diseased plant images than healthy plants. The thermography method has the potential to be an early detection method because it can detect viral infection before visual symptoms appear.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42921593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the obstacles in strawberry production is plant parasitic nematode infection. Ciwidey District is one of the strawberry production centers in Bandung Regency, West Java Province. Several strawberry farms in Ciwidey showed symptoms of nematode infection, which affect the roots and crowns of the plants. There is limited reports of plant parasitic nematodes on strawberry plants in Indonesia , therefore this study was initiated to identify the genera of nematodes associated with strawberries and measure their abundance. Plant samples were taken by a purposive sampling method on symptomatic plants. Soil samples were extracted by centrifugation floatation method, root samples by fogging method; while leaf samples were cut into pieces, soaked in a cup, then incubated in the refrigerator for 24 hours. Nematodes were identified and their abundance was counted. Symptoms of plant parasitic nematode on the strawberry plant canopy involved stunted growth, reddened leaves, curled or wrinkled small leaves, and chlorosis. Symptoms on the roots are in the form of root lesions, shortened roots, reduced number of roots, swelling at the tip of the root, and root galls. Six species of nematodes were identified from all samples, i.e. Aphelenchoides besseyi, A. bicaudatus, Meloidogyne spp., Pratylenchus sp., Scutellonema sp., and Tylenchus sp. The abundance of nematodes found varied between 1–42 nematodes per 100 mL-1 soil and 2–29 nematodes per 5 g root-1. Among the nematodes found, Scutellonema was the first nematode reported to be associated with strawberry plants in Indonesia.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49286587","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
