Characterization of Fusarium wilt of banana in São Paulo, Brazil. Repositório Alice
RODRIGUEZ, M. A. D.; VIEIRA, H. B.; RODRIGUES, F.; ROSSI, C.; HECK, D. W.; SANTOS, A. dos; MORAES, W.; TEIXEIRA, L. A. J..
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...

Deciphering the suppressiveness of fusarium wilt in banana with organic residues. Repositório Alice
HECK, D. W.; GHINI, R.; BETTIOL, W..
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...

Fusarium wilt of banana in Brazil: current state and research advances at Embrapa towards sustainable disease management. Repositório Alice
RODRIGUEZ, M. A. D.; HADDAD, F.; AMORIM, E. P..
Fusarium wilt (FW) impairs banana production in large areas of Brazil, affecting mainly the most profitable cultivars: \'Maçã\' (Silk, AAB) and ‘Prata’ (Pomme, AAB). Plant nutrition is frequently associated with disease severity, but little is known about the banana-FW pathosystem in Brazil. In this work we samples 18 farms in four different production systems in SP. In each farm areas with low (FOC-) and high (FOC+) incidence of FW were selected for plant analysis. Lamina of the third leaf were sampled and analyzed for nutrient content. The main differences between FOC- and FOC+ areas were related to N, K and Ca contents. The most outstanding effect of FW on plant nutrition was the reduction of K and Ca. This might be explained by the fact K and Ca are...

Physical properties as soil health indicators for fusarium wilt of bananas. Repositório Alice
TEIXEIRA, L. A. J.; SILVA, F. R. da; MARQUES, E.; VIEIRA, H. B.; MORAES, W.; RODRIGUEZ, M. A. D..
Fusarium wilt (FW) of banana, caused by Fusarium oxysporum f. sp. cubense (FOC), is a major constraint for banana production in Brazil. Edaphic conditions may act as driving factor of FW intensity and may even result on soil suppressiveness. However, the complex environment of soils and the specificity of physical, chemical and biological interactions, requires integrated approaches to better understand suppressive and conductive soils. Therefore, developing management practices based on soil health are extremely dependent high quality site-specific information of soil and the production systems. This work is part of a set of research actions to identify soil health indicators in banana plantations affected by FW in São Paulo. A survey was carried out in...

SOURCES OF RESISTANCE TO Fusarium oxysporum f. sp.cubense IN BANANA GERMPLASM Rev. Bras. Frutic.
Ribeiro,Lindinéia Rios; Silva,Sebastião de Oliveira e; Oliveira,Saulo Alves Santos de; Amorim,Edson Perito; Serejo,Janay Almeida Santos; Haddad,Fernando.
ABSTRACT Fusarium wilt (syn= Panama disease), caused by Fusarium oxysporum f. sp. cubense (FOC), is one of the most destructive diseases of banana, being genetic resistance the main management strategy for this disease. Since the pathogen is constantly evolving to supplant the genetic resistance, new sources of resistance must be investigated by genetic improvement programs aiming to developing new varieties. The objective of the present study was to identify sources of resistance from the different accessions maintained in the banana active germplasm bank (BAGB) at Embrapa Mandioca e Fruticultura. Forty-one BAGB accessions were evaluated, including 17 diploids, 21 triploids, and two tetraploids. The area under the disease progress curve, disease index,...

Spatial pattern analysis of Fusarium wilt of banana in Brazil. Repositório Alice
HECK, D. W.; RODRIGUEZ, M. A. D.; DEL PONTE, E. M.; MIZUBUTI, E. S. G..
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...
