| Abstract The acerola tree (Malpighia emarginata Sessé &Moc. ex DC.) is a fruit species that has prospered in the Brazilian tropical regions, especially in the Northeast, thanks to the high content of vitamin C in the fruits, among other characteristics that make it attractive to the producer, such as early production. Although there is increasing demand for the product, the production of certified seedlings of good commercial varieties is still a barrier to further expansion of the crop. This review aims to present, in a comprehensive way, technical information on how the spread has been made since its introduction in the country, as well as innovations and advances. Traditionally, propagation is carried out through seeds, cuttings and by grafting on... |

| Over the last few years, considerable effort has been spent by Embrapa in the construction of a plant disease database representative enough for the development of effective methods for automatic plant disease detection and recognition. In October of 2016, this database, called PDDB, had 2326 images of 171 diseases and other disorders affecting 21 plant species. PDDB size, although considerable, is not enough to allow the use of powerful techniques such as deep learning. In order to increase its size, each image was subdivided according to certain criteria, increasing the number of images to 46,513. Both the original (PDDB) and subdivided (XDB)databases are now being made freely available for academic research purposes, thus supporting new studies and... |

| Macrophomina is a genus belonging to Botryosphaeriaceae that comprises well-known necrotrophic pathogens related to hundreds of plant hosts around the world. Historically, M. phaseolina is the causal agent of charcoal rot in several crops, mainly in tropical and subtropical areas around the world. However, after a recent genetic diversity study using morphological and molecular approaches, which resulted in the epitypification of M. phaseolina, and the description of a new Macrophomina species associated with charcoal rot disease, the hypothesis that other cryptic species could be present under the name M. phaseolina was raised. Previous studies in Brazil revealed a high genetic diversity and different levels of aggressiveness of M. phaseolina isolates... |

| Cucurbits have great economic, nutritional and social importance in the Brazilian semiarid region. In this region, many factors can result in reduced productivity of these crops, especially fungal and viral diseases. Therefore, knowledge of cucurbits is crucial for proper disease management. The objective of this work was to identify the major diseases of cucurbits grown in some municipalities in the Hinterland of the state of Pernambuco. Thus, plant samples were collected with symptoms in crops in the municipalities of Salgueiro, Serra Talhada, Floresta, Petrolândia, Ibimirim, Custódia and Inajá. A questionnaire was also applied to gather information about the production profile of producers. Seven fungal pathogens infecting cucurbits were identified:... |

| Maize plants infected with Spiroplasma kunkelii show symptoms similar to that of plants in a magnesium-deficient soil, and it has been shown that the spiroplasma alters the plants' magnesium absorption. In the current study we compared changes associated to either spiroplasma infection, two soil magnesium levels and their combinations. Plant symptoms were recorded and correlated with transmission electron microscopy observations. Plants grown on a high magnesium treatment showed no macroscopical alterations nor organelle ultrastructural alterations, while plants on a low magnesium treatment showed macroscopical vein yellowing and, ultrastructurally, they had most chloroplasts and mitochondrial membranes altered. Infected plants on a low magnesium treatment... |

| As barreiras fitossanitárias impactam o setor produtivo e comercial de diversos países que pretendem exportar seus produtos agrícolas, em face das exigências que impõem a trânsito internacional de vegetais. Entretanto, essas normativas visam a proteger os importadores do ingresso e disseminação de pragas em seu território. A certificação fitossanitária de origem (CFO) e a permissão de trânsito de vegetais (PTV), documentos que atestam a sanidade e garantem a rastreabilidade das partidas, são exemplos das exigências fitossanitárias interestaduais. A Bahia, segundo lugar no ranking nacional de produção de citros, foi reconhecida pelo Ministério da Agricultura, Pecuária e Abastecimento (MAPA) como área de não ocorrência de várias pragas da citricultura, das... |
