However, its production is being limited by vine rot infection caused by Athelia rolfsii. Information on the epidemiology in growing regions is important for the disease management. Hence, this study was conducted to investigate the incidence and severity of vine rot disease of Telfairia occidentalis in commercial fields across Abak, Akwa Ibom State. A total of nine established T. occidentalis fields in three locations, including the Cross River Basin Development Authority, Abak-Irrigation Project, were visited during the peak of dry season (November – December), 2021 and raining season (June - August), 2022 respectively. The fields were scored for vine rot disease incidence and severity using a well described scale. Random samples from symptomatic plants were collected and taken to the laboratory for fungi isolation and identification. Koch postulate was carried out to confirm the causal agents on one susceptible genotype of T. occidentalis in the study area. Overall number of plants showing varying levels of symptoms reaches 84% and total values for mean incidences’ rate (3.31 ± 0.06      and 3.19 ± 0.06) were recorded for both sampling period respectively. The result of this study revealed that the prevalent fungal pathogen that is responsible for vine rot and wilt disease of T. occidentalis in the study is A. rolfsii and presented information on the level and severity of infection that is indicative of the need to implement appropriate control measures for A. rolfsii disease in the study area.","PeriodicalId":512286,"journal":{"name":"Asian Plant Research Journal","volume":"23 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139958370","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}

{"title":"Exploring the Antimicrobial Efficacy of Embelia Keniensis Leaf Extracts against Selected Microbial Strains","authors":"Henry Githinji, P. K. Njenga","doi":"10.9734/aprj/2024/v12i1237","DOIUrl":"https://doi.org/10.9734/aprj/2024/v12i1237","url":null,"abstract":"The pursuit of novel bioactive compounds from natural sources has prompted an assessment of the antimicrobial properties and phytochemical composition of Embelia keniensis leaf extracts. Embelia keniensis is one of the five Myrsinaceae species endemic to Kenya. The interest in the scientific investigation of Embelia keniensis crude extracts is based on the claims of their effective use for the treatment of many diseases such as chest pains, common cold and stomach ailments. The plants used in this study were derived from Brackenhurst Botanical Garden Limuru sub-county, Kiambu County, central Kenya. The study was conducted from January to March 2023 at the Jomo Kenyatta University of Agriculture and Technology. The study aimed to evaluate the antimicrobial potential of crude extracts of this plant against Escherichia coli, Staphylococcus aureus, and Candida albicans. The antimicrobial activity was determined through the disc diffusion method. Both methanol and water were employed for extraction; however, neither demonstrated promising activities against the test organisms. Notably, the water extract exhibited greater potency compared to the methanolic extract against Escherichia coli. The water extract displayed a maximum inhibition zone of 9mm at a concentration of 1mg/ml. similar findings were observed for Staphylococcus aureus and Candida albicans with inhibition zones of 9mm and 7 mm, respectively, at the same concentration. Preliminary phytochemical screening identified the presence of bioactive agents such as saponins and flavonoids, while tannins and terpenoids were absent. Despite the observed zones of inhibition, the plant extract fell short of meeting the clinical and laboratory standards institute breakpoints for susceptibility and intermediate levels. Instead, they exhibited resistance breakpoints, rendering the plant extracts ineffective for antimicrobial activities. Nevertheless, this outcome does not negate the potential of the plant extract. Factors like mode of action and microorganism susceptibility could influence their effectiveness. Further evaluation is warranted to fully comprehend the potential of Embelia keniensis extracts. This study provides insight into their antimicrobial activity and a preliminary phytochemical profile.","PeriodicalId":512286,"journal":{"name":"Asian Plant Research Journal","volume":"30 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140497051","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}
