13. RB975242 and RB975201 - Late maturation sugarcane varieties
Abstract The sugarcane varieties RB975201 and RB975242 were developed and released for harvest at the end of the season (late maturation) in the Central-South region of Brazil. In specific environments, these varieties were compared with commercial standards in sugar yield per area. They are resistant to major sugarcane diseases and present the Bru1 gene of

14. Evaluation of sugarcane introgression lines for resistance to brown rust disease caused by Puccinia melanocephala
Sugarcane brown rust disease caused by Puccinia melanocephala is one of the important fungal diseases affecting sugarcane yield around the world. Cultivar resistance is the most appropriate control method for this disease. In this study, 62 introgression lines chosen from the crossing Saccharum officinarum L. cv. Ludashi x Erianthus rockii Yunnan 95-19 were

15. 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

16. Estabelecimento de um patossistema modelo e análise da interação molecular planta-patógeno entre Eucalyptus grandis e Puccinia psidii Winter por meio da técnica de RNA-Seq. / Establishment of a model pathosystem and analysis of the molecular plant-pathogen interaction between Eucalyptus grandis and Puccinia psidii Winter
More than 20 million hectares are destined to Eucalyptus plantations worldwide and Brazil has the second largest planted area. The International Eucalyptus Genome Network, EUCAGEN, was created in 2007 in order to perform genomic research on Eucalyptus. Brazil provided the biological material from the model tree (Brasuz) to have the complete genome sequenced

17. Métodos para preservação de urediniósporos de Puccinia Kuehnii
Among the diseases of the culture of sugarcane in Brazil stands out the rusts. Currently, the most worrying is the orange rust due their potential for harm. The objectives were to test the feasibility periods of uredinósporos, preservation methods and influence of aqueous extracts in the in vitro germination urediniospores of Puccinia kuehnii.The work was d

18. Additional physiological races of coffee leaf rust (Hemileia vastatrix) identified in Kenya
Coffee leaf rust (CLR), caused by the fungus Hemileia vastatrix, is among the most important diseases affecting coffee all over the world. In Kenya, it is currently the second most important disease, and breeding coffee to obtain new resistant cultivars has been a priority. Over time, new rust pathogenic races able to infect hitherto resistant coffee genotyp

19. Variabilidad de Puccinia sorghi en la zona maicera núcleo Argentina
Common rust caused by Puccinia sorghi is one of the endemic diseases of corn in Argentina. It appears every year with different levels of severity depending on the genotype of the host, the biotypes of the pathogen, and the environmental conditions. Estimates of grain weight losses ranged from about 3 to 8% for 10% of the total leaf area affected. P. sorghi

22. 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

23. 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

24. FREQUÊNCIA E ÉPOCA DE APLICAÇÃO DE FUNGICIDAS E SEUS EFEITOS EM HÍBRIDOS DE MILHO (Zea mays L.) / FREQUENCY AND TIME OF APPLICATION OF FUNGICIDES AND ITS EFFECTS IN THE HYBRIDS MAIZE (Zea mays L.)
Among the major diseases with potential for reducing the final yield of maize (Zea mays) are common rust (Puccinia sorghi), and Spot Blotch (Exserohilum turcicum). Seed companies offer hybrids with levels of disease resistance in the shoots, however, these have demonstrated the need for alternatives that help to maintain the low rate progress of diseases. Gi
