In this study, symptomatic guava tissues were collected from infected orchards in southern Taiwan for pathogen isolation and identification. Samples comprised diseased leaves, fruits, and branches of guava cv. Jen Ju Pa. Based on morphological observations and multilocus phylogenetic analyses, the causal agents of GSD in these fields were identified as <em>Neopestalotiopsis</em> spp., closely allied with <em>N. cubana</em> and <em>N. protearum</em>. Due to increasing concerns over fungicide resistance and environmental sustainability, we also explored biological control as an alternative strategy. Three endospores-forming bacteria strains (PM-SSH-B009, PM-SSH-B018 and PM-SSH-B060) were isolated from rhizosphere soil of local orchids in southern Taiwan and identified as <em>Bacillus amyloliquefaciens</em> by 16S <em>rDNA</em> sequencing. For PM-SSH-B009 and PM-SSH-B018, the gyraseA (<em>gyrA</em>) sequencing provided additional resolution consistent with <em>B. amyloliquefaciens</em>; however, <em>gyrA</em> could not be resolved for PM-SSH-B060. In vitro assays demonstrated that these strains significantly inhibited the mycelial growth and spore germination of <em>Neopestalotiopsis</em> spp., causing abnormal swelling of germination tubes and hyphae. On detached fruit, three application timings were compared to assess practical efficacy. Co-inoculation and pre-inoculation with PM-SSH-B018 or PM-SSH-B060 reduced GSD severity, whereas post-inoculation was less effective. These findings support <em>B. amyloliquefaciens</em> as a promising component of integrated GSD management, and provide a foundation for subsequent studies to resolve the underlying antifungal mechanisms and optimize field deployment.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"24 ","pages":"Article 102329"},"PeriodicalIF":6.2,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145021008","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}

It serves as a versatile crop in Africa, America, Asia, and Oceania and is beneficial to more than one billion people. This bibliometric study used published data from the last 35 years (1990–2024) and <em>de novo</em> phylogenetic reconstructions to review the current state of knowledge on the importance of <em>C. cajan</em> cultures and their associated symbiotic bacteria. It focuses on the genetic diversity, taxonomy, symbiotic effectiveness, and valorization status of <em>C. cajan</em> symbiotic rhizobia used as biofertilizers. The study revealed that <em>C. cajan</em> is facing abandonment in some regions, including West Africa. Nevertheless, <em>C. cajan</em> is still considered a multipurpose and highly beneficial crop in over 100 countries because of its exceptional nutritional value, resilience to climate change, and capacity to fix atmospheric nitrogen. To date, diverse strains affiliated with approximately 20 rhizobial species have been isolated from <em>C. cajan</em> nodules, all of which are scattered within seven genera of α-proteobacteria (<em>Bradyhizobium</em>, <em>Mesorhizobium, Phyllobacterium</em>, <em>Rhizobium, Neorhizobium,</em> and <em>Sinorhizobium</em>) and β-proteobacteria (<em>Paraburkholderia</em>), with <em>Bradyhizobium</em> strains being the major isolates. The high diversity of strains forming an effective symbiosis with <em>C. cajan</em> suggests a broad host range for this legume. It was shown also that <em>C. cajan</em> is a reservoir for the discovery of novel rhizobial taxa, including symbiovars and novel species. Moreover, symbiotic effectiveness tests in greenhouse and field conditions led to the selection of highly effective isolates, which are being further challenged to meet industry standards and/or commercialized as biofertilizers, mainly in Australia, Brazil, Côte d’Ivoire, the Dominican Republic, and India. These findings highlight the potential of leveraging indigenous plant-beneficial microbes as a strategy to promote sustainable agriculture.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"24 ","pages":"Article 102328"},"PeriodicalIF":6.2,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145047471","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 CNV herbicides, mineral fertilizers, and plowing with chisel plows were used while in ORG no herbicide, low urea fertilizer, moldboard plow, and the return of soybean residues to soil after harvest were used.
