“…According to the Brazilian Ministry of Agriculture, a decade ago Moko was present in some of the northern and northeastern Brazilian states ( MAPA, 2007 ). Later, in 2009, the disease was reported in two other states: in banana, in Alagoas ( Andrade et al, 2009 ) and in two Heliconia species and in an ornamental Musa ( M. coccinea ) in the Federal District ( Zoccoli et al, 2009 ; Figure 1 ).…”

Bacterial wilt induced by the Ralstonia solanacearum species complex is endemic to Brazil, where it can cause variable losses in many hosts. Its economic importance, however, cannot be precisely measured due to Brazil’s continental size, subject to variable weather conditions which directly affect disease expression. The objectives of this paper were (i) to gather scattered information on historical facts; (ii) to show the current distribution of the pathogen in the country, and (iii) to comment on future trends on the importance of the disease in economically important current and potential hosts, based on the pathogen’s variability and the global climate change under way.

“…Pratylenchus coffea foi detectado apenas em Presidente Tancredo Neves, Maraú e Ibirapitanga (Tabela 4). Estas áreas estavam próximas de plantações de gravioleiras, citros e outras frutíferas, que são citados como hospedeiros (Souza et al, 1999;Moura, 2005;Andrade et al, 2009). Provavelmente devido à bananeira não ser um hospedeiro tão favorável, e por esta espécie ter menor número de hospedeiros, menor disseminação (Gowen e Quénéhervé, 1990), entre outros fatores.…”

Plant parasitic nematodes associated with bananas plantings in the south region of Bahia. Brazil is a major producer of fruits, and the State of Bahia is second largest bananas producer of bananas. However the cultivation of bananas (Musa spp.) has been showing yield losses due to inappropriate management practices and phytosanitary problems. Plant parasite nematodes are among the pathogens which can cause ham to this crop. As such, the objective of this work was to survey the plant-parasitic nematodes associated on crops of banana in 12 municipalities from the south region of Bahia in the period of December 2011 to November 2012. The nematodes found were Helicotylenchus multicinctus, H. dihystera, Meloidogyne incognita, M. javanica, Meloidogyne sp., Paratylenchus sp, Pratylenchus coffeae, Radopholus similis and Rotylenchulus reniformis. The highest population levels were H. multicinctus, R. similis and Meloidogyne spp. With 117.144,00, 18.648,00 e 16.498,00, respectively. Lack of knowledge of farmers about the nematoses, not adopting management practices and lack of technical assistance may explain the wide spread and high population levels of nematodes found.

“…This biovar was isolated from areas planted for the first time with solanaceae in the Amazon region, after the forest was felled, suggesting the presence of a yet non-identified native host for R. solanacearum in the forest (COELHO NETTO et al, 2004). Biovar 2T occurs in low altitude tropical climate regions and seems to have the Amazon region as its center or origin, presenting lower soil survival than biovars 1 or 3 (COELHO NETTO et al, 2004 NETTO et al, 2004;ANDRADE et al, 2009). Race 2 is considered as a present quarantine pest (A2), occurring in the States of Amapá, Amazonas, Pará, Rondônia, Roraima, and Sergipe, and is restricted only to banana (Musa spp.)…”

ABSTRACT:Ralstonia solanacearum is a gram-negative soil-borne bacterium capable of infection of hundreds of vegetable species over more than 50 botanical families, causing bacterial wilt, except for bananas, when the disease is called Moko. It deserves special attention, from all other plant pathogenic bacteria, for its high phenotypic and genotypic plasticity, a characteristic that makes disease control extremely difficult. In this context, frequent and necessary surveys are conduct in the attempt of characterizing the prevailing strains of R. solanacearum in each region where the disease has been reported. However, knowledge about occurrence and diversity of R. solanacearum in Brazil is fragmented and in some cases, based on inconclusive studies with few strains, little representative of a given region. The need to obtain a greater picture guided this review. The occurrence of this bacterium in Brazilian States and the possible causes for its dissemination are presented, with emphasis on studies of genetic variability of populations of R. solanacearum in the country. The compiled results report a wide distribution of the bacterium in Brazil and great variability of its populations among locations. Partly due to the difficulty of detecting small titer of bacteria in samples, paucity of information about the origin of inoculum in certain regions is observed, as well as the need for detecting the presence of the pathogen in asymptomatic plants, potato tubers with latent infections, soil, and water, which are the major causes of bacterial dissemination into areas without any disease history.
