| Fusarium wilt (FW) is a major constraint for banana production in São Paulo, the biggest banana producer in Brazil. Farmers cultivating ?Maçã? (AAB) and ?Prata? (AAB) (AAB) are usually forced to abandon areas or switch to less profitable varieties. Despite it impact, there is lack of detailed knowledge of FW incidence, distribution and factors associated to epidemics. In this work we characterized 20 farms from four regions representative of different production systems. Incidence of FW was evaluated in all the farms and diseased plants were geo-referenced. In each farm areas with high (FOC +) and low (FOC-) incidence of FW were selected. Comparative analyses of weevils and nematode populations, as well as, soil nutrients were performed. Values of FW... |

| Fusarium wilt (FW) is a major constraint for banana production in São Paulo. Farmers cultivating 'Maçã' (AAB) and ?Prata? (AAB) are usually forced to abandon areas or switch to less profitable varieties. Despite it impact, there is lack of detailed knowledge of FW incidence, distribution and factors associated to epidemics. In this work we evaluated 18 farms from four regions representative of different production systems. In each farm, areas with high (FOC +) and low (FOC-) incidence of FW were selected. Comparative analyses of weevils and nematode populations, as well as, soil and plant nutrients were performed. Values of FW incidence varied 2 to 45% according to the production systems, but were consistently higher in ?Maçã? than in ?Prata?. Use of... |

| The use of organic residues in agriculture can contribute for the management of plant diseases and soil fertility. However, their effects are poorly understood for banana Fusarium wilt (FW), caused by Fusarium oxysporum f. sp. cubense (Foc). In this study was evaluated the biotic and abiotic effects on soil suppressiveness to banana FW after incorporation of composted sewage sludge, biochar, shrimp peel and mussel shell into the soil. Residues were incorporated (0, 1, 2, 3, 4, and 5%, v:v) in soil previously infested with Foc. Plantlets of banana cv. ?Silk? (AAB) were transplanted seven days after residues incorporation in 2 L pots. The assays were conducted in greenhouses located at the Embrapa Meio Ambiente, Jaguariúna, São Paulo, Brazil. A completely... |

| Understanding plant disease epidemics is key to establish efficient management strategies. Several factors can affect epidemic patterns of Fusarium wilt (FW) of banana in the field, but little is known about temporal and spatial patterns of this disease worldwide. This work aimed to assess the incidence and the spatial pattern of FW of banana in four production regions in Brazil. Seventeen fields planted with ?Silk? or ?Prata? were evaluated. In each field, all plants were visually assessed and diseased plants were geo-referenced. Incidence maps were constructed based on geo-referenced data. A quadrat-based, using three sizes of quadrats, and a point-process distance-based methods were used to detect spatial patterns. The null hypothesis of complete... |

| Fusarium wilt (FW), caused by the soil-borne fungus Fusarium oxysporum f. sp. cubense , is a highly destructive disease and a major threat to the banana industry. Understanding how FW epidemics develop is key to establish efficient management strategies. Epidemiological factors such as weevil borer, wind, water and cultural practices have been suggested to affect epidemics. Temporal and spatial patterns of FW remain poorly investigated worldwide and no study was conducted in Brazil. This work aimed to assess the incidence and the spatial pattern of FW for gaining understanding about epidemic processes. Fourteen fields planted to ?Maçã? (Silk, AAB) or ?Prata Mineira? (Pome, AAB) located at four banana-producing regions of the states of São Paulo and Paraná... |
