A total of 56 E. tracheiphila were recovered from the symptomatic cucumber plants among which 13 were tested highly virulent. Among six rhizobacterial isolates; Pseudomonas flurescens-3 (Pf-3), Pseudomonas putida-5 (Pu-5), Pseudomonas stutzeri-2 (Ps-2), Bacillus subtilis-1 (Bs-1), Bacillus safensis-2 (Bs-2), and Pseudomonas stutzeri-1 (Ps-1), tested in vitro using dual culture technique against extremely virulent strain of E. tracheiphila revealed Pf-3, Pu-5 and Bs-1 significantly reduced its growth. Two separate experiments were performed to investigate the synergistic effects of these PGPRs in combination with Airone chemical (active ingredients; Copper Oxychloride + Copper Hydroxide 20%SC by Swat Agro Chemicals, Pakistan) on disease severity and overall plant growth. In the first experiment, eight treatments were tested in a complete randomized design (CRD) with eight replications, focusing on the combination of Pf-3, Pu-5 and Bs-1. Results revealed that the combined application of Pf-3 and Pu-5 significantly outperformed other treatments, exhibiting substantial improvements in key growth parameters; vine length, number of leaves and branches per plant, and a remarkable reduction in disease severity compared to positive and negative controls. In the second experiment, Pf-3, Pu-5 and Bs-1 and Airone chemical were employed in seed and soil treatments to confer resistance to E. tracheiphila and suppress bacterial wilt. The treatment involving P.u-5 and Bs-1, along with a foliar spray of Airone, recorded the lowest disease severity and an increase in plant growth compared to the positive control. These findings suggest that the synergistic application of PGPR and Airone chemical holds promise for integrated disease management in cucumber, providing effective control of bacterial wilt while promoting plant growth. Moreover, the environmentally friendly nature of rhizobacterial-based formulations underscores their potential as safe alternatives for controlling soil-borne plant pathogens without adverse effects on human health or the environment","PeriodicalId":36106,"journal":{"name":"International Journal of Phytopathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139132204","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}

However its production and productivity is threatened due to Covered kernel smut disease. A field experiment was carried out at Aburin Agricultural Research Center at Gabilay district in Somaliland in order to identify management options for Covered kernel smut disease of sorghum. The experiment consisted of 12 factorial treatment combinations of three varieties (i.e., Faruryogele, Abadro and Kuso) and three types of seed treatments which includes synthetic and bio-fungicides (i.e., Apron star 42WS%, Cow urine, and Neem seed kernel extract) and including Untreated control, laid out in RCBD with three replications. Parameters such as disease incidence, disease severity, phenological data, grain yield (kg)/plot, actual grain yield/plot, 1000 grains weight (g) and yield loss (%) were collected. The experiment result showed that highest disease (44.0%) incidence was recorded on untreated Kuso variety while lowest disease (4.33%) incidence was Apron star with Abadiro. Similarly, the highest disease severity (37%) was scored from Untreated Abadiro whereas lowest disease severity (4%) was scored from Abadiro with Apron star and Faruryogele with Apron star. Untreated Abadiro variety reached highest AUDPC (1036.0% days). The Apron star treated varieties had the lowest AUDPC and consistently showing markedly low infection rates indicating that they were more effective to the disease relative to the other seed treatments. The highest yield (1896 kg ha-1) was recorded from Faruryogele with Apron star and lowest (933 kg ha-1) was recorded from untreated Abadiro and Faruryogele. So, Apron star was effective to reduce the yield loss of sorghum and could be recommended to manage sorghum covered kernel smut. However, the experiment should be repeated across different environments over years in order to give the right recommendations and its rate may need to be well defined.","PeriodicalId":36106,"journal":{"name":"International Journal of Phytopathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139133281","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}

The purpose of this study was to investigate the role of PRs, and oxidative isozymes in the protection of tomato plants from oxidative damage induced by viral infection in 16 tomato genotypes. A total of 16 tomato genotypes were evaluated against TSWV and ToMV separately. Changes in the content of protein and defense enzymes were studied in tomato genotypes resistant and susceptible to TSWV or ToMV. The results of the investigation showed that 16 tomato lines gave different responses to infection with TSWV or ToMV [highly resistant (HR), resistant (R), moderately resistant (MR), moderately susceptible (MS), and susceptible (S)]. In this study, the total soluble protein profiles, polyphenol oxidase (PPO), and peroxidase (POX) isozymes of the healthy tomato plants and the TSWV or ToMV infected ones were estimated by electrophoresis in Polyacrylamide gel electrophoresis (PAGE). The results showed quantitative and qualitative differences in the number of bands among the 16 tomato genotypes. Thus, the protein content and isozyme activities were increased or decreased or not changed in inoculated tomato plants with TSWV or ToMV, compared with the un-inoculated plants, depending on the genotype, virus, and degree of resistance. On the other hand, it was found a negative or low-positive correlation between disease incidence and (protein content and isozyme activities). Therefore, it is important that to understand the defense strategy of plants against viruses and how tomato plants defend themselves from virus invasion.

However, little information is available on the variation of aggressiveness of the newly emerging FHB collection compared to old one. It is therefore important to determine to what extent FHB populations can be selected for increased aggressiveness by wheat cultivars with several levels of quantitative resistance. To this end, FHB populations were sampled in 2005 (old population) and in 2015 (new population) from one of the major Syrian wheat production regions, chosen as a location where head blight occurs regularly. New and old FHB isolates were characterized for aggressiveness by single-floret inoculation under controlled conditions on eight durum and bread wheat cultivars of contrasting susceptibility to FHB, and molecularly distinguished using DNA markers. Results showed the new population caused a higher disease severity (ranging from 55% to 67%) than the old population. Thus, their aggressiveness increased between early and late samplings, suggesting that wheat plants cultivated over 10 years selected for increased aggressiveness during epidemics. Our comparative population genetic analyses with analyzed markers showed that the new population had more polymorphic loci compared with the old one. The information obtained in this study indicated that FHB populations adapt to prevailing wheat cultivars, irrespective of their resistance levels, and can therefore overcome polygenic, quantitative resistance. Adaptation to wheat resulting in increased pathogen aggressiveness that was not specific may render quantitative resistance nondurable if not properly managed","PeriodicalId":36106,"journal":{"name":"International Journal of Phytopathology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139136694","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}
