“…Nevertheless, there is no information on yield losses due to charcoal rot on castor in Brazil. Macrophomina phaseolina (Tassi) Goid., the fungus causing charcoal rot infects more than 500 plant species, including some of the world's most important crops such as soybean, cotton and corn (Su et al 2001;Gupta et al 2012). In Brazil, charcoal rot is common and it is considered one of the most prevalent disease problems of soybean (Reis et al 2014).…”

“…The fungal infection and disease development are favored by high temperatures and drought (Dhingra and Sinclair 1978;Grezes-Besset et al 1996;Gupta et al 2012) and in Northeastern Brazil, castor is usually cultivated under such conditions (Severino et al 2012). Moreover, castor is frequently cultivated in association or in rotation with crops that are also susceptible to M. phaseolina, such as cowpea, corn and cotton, allowing the maintainance of high populations of the fungus in the soil.…”

Charcoal rot, caused by Macrophomina phaseolina, is one of the most important diseases of castor (Ricinus communis) in the growing regions of Northeastern Brazil, particularly in the State of Bahia, which concentrates 65% of the country's production. The pathogenicity and aggressiveness of the charcoal rot pathogen was assessed in twenty-seven isolates of M. phaseolina obtained from six plant species: Ricinus communis (n=21), Gossypium hirsutum (n=2), Sesamum indicum (n=1), Helianthus annuus (n=1), Jatropha gossypifolia (n=1) and Arachis hypogaea (n=1). All isolates were pathogenic and exhibited a range of aggressiveness towards BRS Energia cultivar regardless of their host of origin.

There is no comprehensive survey of the presence of fungi associated with lima bean seeds. The objective of this study was to evaluate the fungal diversity of 34 samples of lima bean seeds, acquired with farmers and markets during the years 2014 and 2015 in the states of Ceará, Maranhão, Paraíba and Piauí. Subsamples of 400 seeds were sterilized by soaking in 1% NaOCl solution for 3 minutes, followed by two washes in sterile distilled water, and dried at room temperature. Seeds were placed in Petri plates containing Potato Dextrose Agar, and incubated at 25 C for seven days. Fungal identification was based on morphological markers, and its incidences were quantified. Isolates from the main phytopathogens were also identified by the amplification and sequencing of housekeeping genes. Samples presented variations in diversity and incidence, with the presence of 22 fungal genera. Aspergillus spp., Penicillium spp., Curvularia sp. and Monilinia sp. corresponded to 63.76% of the colonies observed. Among the phytopathogens, isolates of Macrophomina phaseolina, Colletotrichum truncatum, Rhizoctonia solani, Fusarium udum and Fusarium oxysporum were identified by BLASTn analysis (99 to 100% DNA similarity) and phylogenetic analysis. C. truncatum and M. phaseolina presented the highest incidences (0.95% and 1.58%, respectively) among phytopathogens. Keywords: Colletotrichum truncatum, Macrophomina phaseolina, Phaseolus lunatus, seed pathology DIVERSIDADE FÚNGICA EM SEMENTES DE FEIJÃO-FAVA RESUMONão existe levantamento abrangente da presença de fungos associados a sementes de feijão-fava. O objetivo deste trabalho foi avaliar a diversidade fúngica de 34 amostras de sementes de feijão-fava, adquiridas com produtores rurais e em feiras livres, durante os anos de 2014 e 2015, nos estados do Ceará, Maranhão, Paraíba e Piauí. Subamostras de 400 sementes foram desinfestadas, e incubadas a 25 C durante sete dias em placas de Petri contendo meio de cultura Batata-Dextrose-Ágar. A identificação dos fungos foi realizada com base nos marcadores morfológicos, e suas incidências foram quantificadas. Isolados dos principais fitopatogógenos também foram identificados pela amplificação e sequenciamento de genes "housekeeping". As amostras apresentaram variações na diversidade e incidência, com a presença de 22 gêneros fúngicos. Aspergillus spp., Penicillium spp., Curvularia sp. e Monilinia sp. corresponderam a 63,76% das colônias observadas. Dentre os fitopatógenos, os isolados de Macrophomina phaseolina, Colletotrichum truncatum, Rhizoctonia solani,Brazilian Journal of Biosystems Engineering v. 11(1): 79-87, 2017 80 Fusarium udum e Fusarium oxysporum foram identificados por análise BLASTn (99 a 100% de similaridade de DNA) e análise filogenética. C. truncatum e M. phaseolina apresentaram as maiores incidências (0,95% e 1,58%, respectivamente) dentre os fitopatógenos.

“…phaseolina are found in large numbers on plant hosts such as soybean, common beans, peanuts, cotton, sunflower, castor beans and maize (GUPTA et al, 2012;SARR et al, 2014). Tissue infection and colonization may occur in young plants; although symptoms such as charcoal or grey soybean root or stem rot are more visible in the reproductive phase.…”

Root rot (RR), which can occur in different cropping systems, affects soybean seed yield. The aim of this study was to determine the incidence of RR in soybean crop systems and its relationship with soybean yield. The study was carried out for two growing seasons in a no-till system consisting of four soybean crop systems: soybean-oat+soybean-oat, soybean-maize+soybean-maize, soybean-wheat+soybean-wheat and soybean-pasture+soybean-pasture. Data were submitted to Pearson’s correlation. Incidence of RR, mainly charcoal rot and sudden death, was more than 50% in soybean roots for all the soybean crop systems and consequently decreased yield by around 22kg ha-1 of seed for every 1% increase in RR. Root rot led to a decline in seed yield from 20 to 102kg ha-1 in the first season and 9 to 32kg ha-1 in the second season, considering all the cropping systems. Soybean + pasture was the lowest productive system, with a negative RR impact of 74.9 and 32.9kg ha-1 in the first and second season, respectively.
