1. Extracts of the Native Brazilian Tree Garcinia gardneriana Inhibit Urediniospore Germination of Coffee Leaf Rust Fungus
The fungal Hemileia vastatrix is the causal agent of coffee leaf rust, one of the worst and devastating disease in coffee cultures worldwide. As a result of our research on natural products for the development of novel agrochemicals, we found that the hexane extract from leaves of the Brazilian medicinal plant Garcinia gardneriana, at 500 μg mL-1, inhibited

2. CHEMICAL CONTROL OF ASIAN SOYBEAN RUST AS A FUNCTION OF CULTIVAR, ROW SPACING AND SPRAY BAR SUPPORT SYSTEMS
ABSTRACT Product deposition and foliar surface cover are highly impacting factors on the efficiency of foliar fungicides applied to soybean cultivars, due to their low mobility, with side effects on Asian soybean rust (ASR) control. Spray bar support systems, such as the air curtain (Vortex®) and the use of nozzles along the bar (Dropleg®), stand out as an

3. Effect of adding fungicide to mixtures of triazoles and strobilurins in the control of downy mildew and Asian soybean rust
RESUMO Os fungicidas utilizados para o controle da ferrugem asiática da soja são constituídos por misturas entre os modos de ação sistêmicos (triazóis) e meso-sistêmicos (estrobilurinas). Entretanto, para o controle do míldio da soja, existem disponíveis apenas fungicidas protetores. Objetivou-se avaliar a eficácia de fungicidas com diferentes mod

4. Presence of orange rust on sugarcane in the state of Pernambuco, Brazil
Sugarcane leaf rust symptoms were observed on seven month-old plants in March 2012 at Santa Teresa Farm, north coast of Pernambuco, Brazil. Plants were identified as a genotype coded as RBUFRPE0032 developed by the Sugarcane Breeding Program of Universidade Federal Rural de Pernambuco (UFRPE/EECAC). Evaluations under field conditions showed characteristic le

5. Breeding for common bean (Phaseolus vulgaris L.) rust resistance in Brazil
Common bean is an economically, nutritionally, and socially important crop. It is grown in distinct regions and different seasons around the world by subsistence level farmers with low-technology input as well as by farmers that use high input technologies. One important factor that can limit the bean growing and drastically affect grain yields is the high n

6. Identification of the soybean HyPRP family and specific gene response to Asian soybean rust disease
Soybean [Glycine max (L.) Merril], one of the most important crop species in the world, is very susceptible to abiotic and biotic stress. Soybean plants have developed a variety of molecular mechanisms that help them survive stressful conditions. Hybrid proline-rich proteins (HyPRPs) constitute a family of cell-wall proteins with a variable N-terminal domain

7. APLICAÇÕES DE FUNGICIDAS EM DIFERENTES ESTÁDIOS DA CULTURA DA SOJA EM DOIS LOCAIS
The main diseases occurring in soybean (Glycine max) in Brazil have a great damage potential, requiring additional expenses to control through measures available today, highlighting the fungicides spray. The objective of this study was to evaluate the effect of fungicides spray at different growth stages of soybean, cultivar CD 206, and verify the relation b

8. A web-based bioinformatics interface applied to the GENOSOJA project: databases and pipelines
The Genosoja consortium is an initiative to integrate different omics research approaches carried out in Brazil. Basically, the aim of the project is to improve the plant by identifying genes involved in responses against stresses that affect domestic production, like drought stress and Asian Rust fungal disease. To do so, the project generated several types

10. Impacto do aumento da concentração de CO2 atmosférico sobre a ferrugem asiática e o desenvolvimento de plantas de soja.
Resumo: A concentração de dióxido de carbono (CO2) na atmosfera tem aumentado significativamente nas últimas décadas e as previsões indicam que os valores atuais podem dobrar até o final do século. O presente estudo teve por objetivo avaliar o efeito do aumento da concentração de CO2 atmosférico na severidade da ferrugem asiática da soja, causada

11. Doenças da goiabeira no cerrado.
RESUMO: Várias doenças atacam a goiabeira (Psidium guajava L.) cultivada nas regiões de abrangência do Cerrado. A bacteriose (Erwinia psidii) é a mais importante. No Distrito Federal, essa doença pode provocar perdas de até 85% na produção do período de entressafra. Outras doenças como a antracnose (Colletotrichum gloeosporioides), ferrugem (Pucci

12. Expression analyses of candidate resistance genes in the Rpp4 Asian Soybean Rust resistance locus.
Asian Soybean Rust (ASR), caused Phakopsora pachyrhizi, is considered the most severe soybean disease around the world. Infection of susceptible genotypes leads to early defoliation, incomplete seed development, and yield losses as high as 80%. Five ASR resistance genes have been identified in soybean: Rpp1, Rpp2, Rpp3, Rpp4 and Rpp5. Of particular interest
