Opis:: Fruit rot of tomato is a serious disease caused by Fusarium species. Sampling was conducted throughout Selangor, Malaysia and fungal species identification was conducted based on morphological and gene encoding translation elongation factor 1-α (tef1-α) sequence analysis. Five species of Fusarium were discovered namely F. oxysporum (including F. oxysporum f. sp. lycopersici), F. solani, F. equiseti, F. proliferatum and F. verticillioides. Our results provide additional information regarding the diversity of Fusarium species associated with fruit rot disease of tomato.

Opis:: In this study, about 112 isolates of Streptomyces were isolated from chickpea rhizospheric soils. Among the isolated strains, five showed strong inhibitory effects against chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris in vitro using plate assay and selected for further studies. The selected strains were identified as Streptomyces spp. based on morphological and biochemical characterization as well as 16S rDNA sequences analysis. Our results assigned them to strains related to genus of Streptomyces. In vitro, antagonistic effects of Streptomyces strains against the disease were evaluated through the dual-culture method, volatile and non-volatile metabolites, siderophore, protease and chitinase production. All bacterial strains inhibited mycelial growth of the pathogen ranging from 26 to 44.2% in dual culture assay. The non-volatile extract of five of the Streptomyces strains inhibited more than 50% growth of the pathogen, whereas volatile compounds were less effective on mycelial growth inhibition (20.2 to 33.4%). The ability of the biocontrol agents to produce siderophore and protease were varied, whereas, production of chitinase was detected for all strains. Results of the greenhouse assay indicated that all biocontrol agents reduced disease severity (ranging from 38.7 to 54.8%). Accordingly, strain KS62 showed higher control efficacy (54.8%). In addition, the biomass of chickpea plants (plant height and dry weight) significantly increased in plants treated with Streptomyces strains compared to non-bacterized control. The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. Therefore, evaluating their efficiency under field conditions is needed.

Opis:: Influence of grapefruit extract (GE) on mycelial growth, spore germination, population density of Fusarium oxysporum f. sp. cyclaminis and F. oxysporum f. sp. dianthi and its effectiveness in the control of Fusarium wilt of carnation and Fusarium corm rot of gladiolus (F. oxysporum f. sp. gladioli) was studied. Amendment of PDA with 40 μg of GE/cm³ inhibited mycelial growth about 50%. Drenching of carnation with 165 μg of GE/cm³, immediately after planting, resulted in drastical decrease of colony forming units number of the pathogen and increased healthiness plant stand about 50%. Applied as gladiolus corm soak, GE at conc. 660 μg/cm³ decreased development of Fusarium rot of gladiolus clones at least twice.
Badano oddziaływanie wyciągu z grejpfruta in vitro na wzrost i rozwój grzybni Fusarium oxysporum f. sp. cyclaminis i F. oxysporum f. sp. dianthi. Ponadto analizowano wpływ wyciągu, zastosowanego doglebowo w dawkach 165 i 330 μg/cm³, na dynamikę liczebności populacji F. oxysporum f. sp. dianthi. W trzecim etapie oceniano skuteczność wyciągu w hamowaniu rozwoju fuzariozy naczyniowej goździka i zgnilizny bulw mieczyka. Dodatek wyciągu z grejpfruta do agaru ziemniaczano-glukozowego w dawce 40 μg/cm³ ograniczał wzrost obu gatunków grzybów o około 50%. Wprowadzenie wyciągu do substratu torfowego już w dawce 165 μg/cm³ spowodowało spadek liczebności populacji F. oxysporum f. sp. dianthi o 74% w ciągu 35 dni oraz ograniczenie rozwoju fuzariozy naczyniowej goździka o około 50%. Zwiększenie dawki wyciągu nie miało istotnego wpływu na poprawę zdrowotności goździków. Wyciąg z grejpfruta, zastosowany do zaprawiania bulw mieczyków, spowodował około 2-krotne ograniczenie fuzaryjnej zgnilizny na nowo tworzących się bulwach.

Opis:: Fungal antagonist, Talaromyces flavus, is one of the most important biological agents of soil-borne fungal diseases including Verticillium and Fusarium wilt. In this study, to increase the effectiveness of T. flavus isolates obtained from greenhouse cucumbers and field grown tomatoes five chemical stabilizers were evaluated. Based on the results of previous studies, the most effective substrate for the growth, sporulation and stability of T. flavus isolates related to the above-mentioned plants was a mix of rice bran and peat-moss. Different chemical stabilizers were mixed with the above-mentioned substrate containing spore suspensions of various T. flavus isolates. For each plant, a completely randomized experiment was conducted under greenhouse conditions with seven treatments and three replications. The results of this study indicated that treatments containing sodium nitrate and D-cycloserine were more effective than those containing other stabilizers. The overall results of this study suggest that the use of some chemical stabilizers may enhance the biocontrol potential of fungal antagonists in controlling different plant diseases including Verticillium and Fusarium wilt.

Opis:: Fusarium oxysporum f. sp. pisi (FOP) is a significant and destructive pathogen of field pea in Algeria. In the present study, 50 isolates of F. oxysporum f. sp. pisi, the causal agent of pea (Pisum sativum) wilt, collected from different parts of western Algeria and representing four races of the pathogen, were analyzed for virulence. The wilt incidence ranged from 6.66 to 88.33% on a highly susceptible cultivar (Little Marvel). Twenty-one isolates belonging to four races of FOP and one nonpathogenic F. oxysporum (FO) isolate were analyzed for vegetative compatibility in order to reveal the genetic structure of the population and to check the reliability of the method for the identification of physiological races of FOP. Obtained results showed that the FOP isolates could be classified into four main vegetative compatibility groups (VCGs) that corresponded to races l, 2A, 2B and 5. The race 6 isolate fell into the race 1 VCG. To our knowledge, this is the first such study in Algeria of its kind.

Opis:: The antifungal activities of ethanolic extracts of three Saudi plants; camel thorn (Alhagi maurorum Medic.), caper (Capparisspinosa L.), and pomegranate (Punica granatum L.) were investigated in vitro against Alternaria alternata, Fusarium oxysporum, Phomadestructiva, Rhizoctonia solani, and Sclerotium rolfsii at concentrations of 0, 3, 6, and 9% (v/v). All tested plant extracts; seeds, roots, and rinds had different degrees of antifungal activity against the tested fungi. When compared with the control, the highest antifungal activity was recorded for camel thorn seeds extract at a concentration of 9%, while, pomegranate rinds extract at 9% came in second. Camel thorn rinds extract came in last even when used at a high concentration. The ethanolic extract of camel thorn seeds may be recommended as a potent bio-fungicide. Extensive studies should be undertaken for the ethanolic extract of camel thorn seeds as a strong antifungal agent against fungal plant diseases.
