The application of Bacillus spp. can suppress the twisted disease by secreting secondary metabolites and enhancing soil suppressiveness. This study aimed to determine the effectiveness of adding spraying Bacillus spp. on the disease incidence, production of shallots, and their effect on the diversity of rhizomicrobiome by culture microbe approaches. Bacillus spp. with a density 108 cfu mL-1, Trichoderma asperellum 106 cfu mL-1 was applied by spraying to the shallot. Fungicide chlorothalonil, propiconazole, and prochloraz were used to control the disease. The diversity of rhizobacteria and fungi was analyzed using the ribosomal intergenic spacer analysis (RISA) method. Based on the analysis result, the addition of spraying B. velezensis B-27, combination B. velezensis B-27 and B. cereus RC76, and T. asperellum was unable to enhance the suppression of twisted disease, but it was able to enhance the production of shallot bulbs reaching 7.10, 7.80, and 8.43 ton ha-1. Furthermore, the result revealed the diversity of the rhizomicrobiome, spraying Bacillus sp. showed 39% differences in bacterial diversity with control while T. asperellum caused 43% difference in the diversity. Spraying Bacillus spp. has not been able to suppress the incidence of twisted diseases compared to control. However, the similar disease incidence on a spraying Bacillus spp. and control showed a higher production until 70% compared to control. This result showed that the addition of spraying Bacillus spp. able to increase the tolerance of shallot plants toward twisted disease.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135135625","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}

Leaf spot disease with necrosis symptom is often found in clove plants. Interferences to photosynthesis caused by leaf spot disease can cause plant death. Bacillus is known to inhibit the development of pathogens through nutrient competition and antibiosis mechanism. This study aims to identify Bacillus sp. RJ09 through molecular approach and determine its potential in suppressing the development of Pestalotiopsis sp., the cause of clove leaf spot by in vitro examination. Identification of the fungus was carried out by observing the morphology which included the color of the colony, the shape and size of the conidium of the isolated fungus. Identification of Bacillus sp. RJ09 was performed by polymerase chain reaction (PCR) using a pair of primers that amplified gyrB gene region of ±1400 bp, followed by sequence analysis. The ability of Bacillus sp. RJ09 as a biological agent against fungi associated with leaf spot was determined using an in vitro double culture method. Pestalotiopsis sp. was found as the fungus associated with leaf spot disease and can cause black necrotic spots on the leaves. Molecular identification of Bacillus sp. RJ09 showed the highest similarity value of 99.40% with B. subtilis subsp. subtitles. In vitro dual culture showed B. subtilis subsp. subtilis RJ09 can inhibit the growth of Pestalotiopsis sp. colonies by 75%.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48380192","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}

In Indonesia, the disease devastated Cavendish, an export variety, and many local bananas, such as Pisang Raja, Kepok, and Barangan. Nonetheless, TR4 incidence is unknown in many parts of Indonesia. This study aimed to detect TR4 in local bananas from Pandeglang, the most banana-produced area in Banten Province. A survey was conducted in nine Kecamatan i.e., Banjar, Cadasari, Jiput, Labuan, and Menes. In total, 13 banana accessions showed symptoms of fusarium wilt. Symptomatic pseudostem samples were plated on potato dextrose agar. The monosporic culture was derived from isolation and used for morphological identification and DNA extraction. Based on the morphological characteristics of Fusarium, 27 strains members of 3 species complexes were identified, i.e., F. cugenangense, F. foetens dan F. oxysporum (Fusarium oxysporum species complex; FOSC), F. equiseti dan F. incarnatum (Fusarium incarnatum-equiseti species complex) dan F. solani (Fusarium solani species complex, currently named as Neocosmospora). Molecular detection of TR4 was done using duplex PCR of translation elongation factor-1α (Tef-1α) and TR4 primer specific, giving positive results only on TR4 strains, members of FOSC. This study enhances our knowledge of the spreading of TR4 in an unidentified area in Indonesia. Many of the local bananas in Pandeglang is susceptible to TR4, thus threaten banana cultivation in this area. Further study on the molecular analysis using more genes will give insight into the expanding genetic diversity of Fusarium causing wilt in Banana in the Indonesian collection.","PeriodicalId":31619,"journal":{"name":"Jurnal Fitopatologi Indonesia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41791106","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}
