CHARACTERIZATION OF Fusarium oxysporum ISOLATES AND RESISTANCE OF PASSION FRUIT GENOTYPES TO FUSARIOSIS Rev. Bras. Frutic.
TEIXEIRA,LETÍCIA MAGALHÃES; COELHO,LÍSIAS; TEBALDI,NILVANIRA DONIZETE.
ABSTRACT Passion fruit wilt, caused by Fusarium spp., is one of the most severe diseases for this crop. Although yellow passion fruit is propagated mostly by seeds, the use of rootstocks tolerant to early death could be a management strategy for cultivation in areas with disease history. Thus, this study characterized Fusarium isolates obtained in Triângulo Mineiro and determined the most suitable genotype to use for grafting to reduce losses caused by this pathogen. Mycelial growth and sporulation of Fusarium isolates, in three different growth media, was quantified by measuring colony diameter and by counting the conidia in Neubauer chamber 10 days after growth in malt extract-agar 2%, PDA or CMA at 22 ± 3ºC and 12 hours lighting. Five days later the...

Classification of physiological races of Fusarium oxysporum f. sp. phaseoli in common bean Bragantia
Henrique,Francisco Humberto; Carbonell,Sérgio Augusto Morais; Ito,Margarida Fumiko; Gonçalves,João Guilherme Ribeiro; Sasseron,Graziéle Ramos; Chiorato,Alisson Fernando.
Fusarium wilt, caused by Fusarium oxysporum Schlecht. f. phaseoli Kendrick and Snyder (FOP), is a major disease of common bean, causing large economic losses. Genetic resistance is one of the main mechanisms of pathogen control, and knowledge of the physiological variability is fundamental in breeding for resistant cultivars. Thus, a method of pathogen classification that describes the variability and is useful in plant breeding of isolates from different sources was evaluated by different methodologies. Common bean plants of different sets of differentiating cultivars were inoculated with 25 FOP isolates and 3 controls, totaling 28 isolates evaluated 30 days after inoculation. The variability in the isolates found in this study differs from the results of...

Common bean genotypes for agronomic and market-related traits in VCU trials Scientia Agricola
Chiorato,Alisson Fernando; Carbonell,Sérgio Augusto Morais; Bosetti,Fátima; Sasseron,Graziele Ramos; Lopes,Rodrigo Lorencetti Tunes; Azevedo,Cleber Vinícius Giaretta.
Value for Cultivation and Use (VCU) trials are undertaken when evaluating improved common bean (Phaseolus vulgaris L.) lines, and knowledge of agronomic and market-related traits and disease reaction is instrumental in making cultivar recommendations. This study evaluates the yield, cooking time, grain color and reaction to anthracnose (Colletotrichum lindemuthianum), Fusarium wilt (Fusarium oxysporum f. sp. phaseoli) and Curtobacterium wilt (Curtobacterium flaccumfaciens pv. flaccumfaciens) of 25 common bean genotypes derived from the main common bean breeding programs in Brazil. Seventeen VCU trials were carried out in the rainy season, dry season and winter season from 2009 to 2011 in the state of São Paulo. Analyses of grain color and cooking time were...

Effect of grafting on watermelon growth and yield Thai Agricultural
Islam, M. Shahidul; Bashar, H.M.K.; Howlader, M.I.A.; Sarker, J.U.; Al-Mamun, M.H..
Wilt of watermelon especially caused by Fusarium is a common and serious problem all over the world. Grafting with bottle gourd is a unique solution to control wilt of watermelon. The experiment was conducted in the coastal region of Bangladesh with the direct involvement of the farmers. All the grafted watermelon plants remain alive up to harvesting while more than one-third non-grafted plants died from vegetative to fruiting stage. Fruit yield was observed one and half times higher in grafted fields as compared to non-grafted counterparts.

Evaluation of Antifungal Potential of Leaf Extract of Chenopodium murale Against Fusarium oxysporum f. sp. lycopersici Planta Daninha
NAQVI,S.F.; JAVAID,A.; QURESHI,M.Z..
ABSTRACT: The present study was performed to evaluate antifungal activity and GC-MS analysis of leaf extract of Chenopodium mural against Fusarium oxysporum f. sp. lycopersici (FOL), a highly problematic soil-borne pathogen of tomato. Dried leaves of C. murale were extracted with methanol for 2 weeks and after evaporating the solvent on a rotary evaporator, antifungal bioassay was carried out against FOL. All concentrations (1 to 5%) significantly reduced FOL biomass by 14-45%. The remaining methanolic extract was fractioned with n-hexane, chloroform and ethyl acetate and all these fractions were assayed for their antifungal potential. A 200 mg mL-1 concentration of various sub-fractions reduced fungal biomass significantly by 94-98% over control. All the...

First report of Fusarium oxysporum f. sp. lycopersici race 3 on tomato in Brazil Trop. Plant Pathol.
Reis,Ailton; Costa,Hélcio; Boiteux,Leonardo S.; Lopes,Carlos A..
Fusarium wilt, caused by three races of Fusarium oxysporum f. sp. lycopersici, is one of the most important diseases of tomato (Lycopersicon esculentum). Races 1 and 2 are distributed worldwide whereas race 3 has a more limited geographic distribution with no report thus far in Brazil. Seven F. oxysporum isolates were obtained from wilted tomato plants of race 1 and 2-resistant hybrids 'Carmen' and 'Alambra' in Venda Nova do Imigrante (State of Espírito Santo), Brazil. Virulence assays were performed using a set of the race differential cultivars: 'Ponderosa' (susceptible to all races), 'IPA-5' (resistant to race 1), 'Floradade' (resistant to races 1 and 2) and 'BHRS-2,3' (resistant to race 3). All isolates were highly virulent to 'Ponderosa', 'IPA-5' and...

Molecular fingerprinting of Fusarium oxysporum f. sp. passiflorae isolates using AFLP markers Scientia Agricola
Silva,Aline dos Santos; Oliveira,Eder Jorge de; Haddad,Fernando; Jesus,Onildo Nunes de; Oliveira,Saulo Alves Santos de; Costa,Maria Angélica Pereira de Carvalho.
Fusarium oxysporum f. sp. passiflorae W.L. Gordon (FOP) is one of the most important fungal pathogens of passion fruits. Understanding molecular variation of isolates from different areas is of utmost importance. Molecular fingerprinting on 14 isolates of FOP were conducted using AFLP molecular markers (Amplified Fragment Length Polymorphism), and their genetic variability were estimated. Twenty-five AFLP primer combinations were selected for amplification of FOP isolates and one for Fusarium oxysporum f. sp. cubense W.C. Snyder & H.N. Hansen (FOC), resulting in 99% polymorphic fragments, with an average of 40 fragments per primer combination. Specific fingerprints could be generated for most of the isolates evaluated; we observed a high power of...

Potential of wild Solanum stramonifolium accesses as rootstock resistant to soilborne pathogens in tomato crops Horticultura Brasileira
Pereira,Ricardo B; Pinheiro,Jadir B; Torres,Tiago B; Mendonça,José L; Lucas,Gilvaine C; Guimarães,Jorge A.
ABSTRACT Resistant rootstocks is one of the most effective method to control soilborne pathogens in tomato crops. Thus, this study was installed to evaluate the reaction of Solanum stramonifolium accesses to Fusarium oxysporum f. sp. lycopersici (Fol) races 2 and 3 and to Meloidogyne enterolobii (Me). The seedlings were grown in trays and inoculated separately with Fol races 2 and 3 at 50 days after planting by immersing the roots in the spore suspension (1×106 microconidia mL-1). Then, seedlings were transplanted in pots containing sterilized soil and kept in greenhouse conditions. To study the reaction of S. stramonifolium accesses to nematodes, we used 27-day old seedlings that were also planted in pots and inoculated with 6,000 eggs and second-stage...

Selection of somaclonal variants of the cultivar ‘Prata-Anã’ for resistance to Fusarium oxysporum f. sp. cubense race 1 Rev. Bras. Frutic.
Ferreira,Mileide dos Santos; Moura,Érica Rodrigues de; Lino,Lucymeire Souza Morais; Amorim,Edson Perito; Santos-Serejo,Janay Almeida dos; Haddad,Fernando.
Abstract The banana tree is one of the most cultivated fruit globally; however, some diseases significantly affect its production, such as Fusarium wilt. The most appropriate measure for controlling this disease in areas with inoculum pressure is the use of resistant cultivars. Therefore, this study aimed to generate banana somaclones of the cultivar ‘Prata-Anã’ resistant to Fusarium wilt by inducing somaclonal variation. ‘Prata-Anã’ stem apexes were established in vitro in MS culture medium and, on a monthly basis, subcultivated in AIA and adenine sulfate supplemented MS medium with added plant regulators: 6-benzylaminopurine (BAP, 4 ml L-1), Thidiazuron (TDZ, 1 ml L-1), and Paclobutrazol (PBZ, 10 ml L-1). The treatments were: T0: no regulator, T1: BAP,...
