Phakopsora pachyrhizi is the major pathogen associated with soybean rust in Colombia [PDF]

open access: yes, 2022
Soybean crops grown in the plains of eastern Colombia have been affected by the incidence of rust. This disease, still officially regarded as American soybean rust (caused by Phakopsora meibomiae) by the Colombian Department of Agriculture (ICA), causes ...

Archaeophytopathology of Phakopsora pachyrhizi, the Soybean Rust Pathogen [PDF]

open access: yesPlant Disease, 2015
Herbarium specimens are useful to compare attributes of the past to attributes of today and predictions into the future. In this study, herbarium specimens from 1887 to 2006 were used to identify Phakopsora pachyrhizi and P. meibomiae, the two known fungal species that cause soybean rust.

Identifying and Quantifying Phakopsora pachyrhizi Spores in Rain [PDF]

open access: yesPhytopathology®, 2009
In summers of 2005 and 2006, rain was collected weekly at over 100 selected National Atmospheric Deposition Program/National Trends Network sites across the soybean-growing region of the central and eastern United States. Rain samples were screened for Phakopsora pachyrhizi (causal agent of soybean rust) DNA using a nested real-time polymerase chain ...

Population structure and genetic diversity of Phakopsora pachyrhizi in the Southeastern United States. [PDF]

open access: yesG3 (Bethesda)
Abstract Phakopsora pachyrhizi, the causal agent of soybean rust disease (SBR) on Glycine max (soybean), is considered one of the most globally devastating diseases of soybeans and is a particular problem in Brazil, China, Sub-Saharan Africa, and the southern United States.

Preservation of Phakopsora pachyrhizi Uredospores [PDF]

open access: yesJournal of Phytopathology, 2007
AbstractThis study compared different temperatures and dormancy‐reversion procedures for preservation of Phakopsora pachyrhizi uredospores. The storage temperatures tested were room temperature, 5°C, −20°C and −80°C. Dehydrated and non‐dehydrated uredospores were used, and evaluations for germination (%) and infectivity (no.

The Effect of Solar Irradiance on the Mortality of Phakopsora pachyrhizi Urediniospores [PDF]

open access: yesPlant Disease, 2006
Soybean rust, caused by Phakopsora pachyrhizi, may be the most important foliar disease of soybean. Within the last 10 years, the fungus has moved to many new geographical locations via spread of airborne urediniospores. The objective of this study was to determine the relationship between urediniospore viability and exposure to solar radiation ...

Genetic control of soybean (Glycine max) yield in the absence and presence of the Asian rust fungus (Phakopsora pachyrhizi)

open access: yesGenetics and Molecular Biology, 2008
Soybean is one of the most important crops in Brazil and continuously generates demands for production technologies, such as cultivars resistant to diseases. In recent years, the Asian rust fungus (Phakopsora pachyrhizi Syd. & P.

Comparative Susceptibilities of Legume Species to Infection by Phakopsora pachyrhizi [PDF]

open access: yesPlant Disease, 2008
Knowledge of the host range of Phakopsora pachyrhizi is important to agriculture in the United States because of the distinct possibility that economic losses could occur to crops other than soybean. Furthermore, it is possible that alternative hosts could provide a means of overwintering of the pathogen, providing inoculum to initiate epidemics in ...

Tratamento de semente e aplicação foliar de fungicidas para o controle da ferrugem-da-soja Seed treatment and foliar fungicide application to control soybean rust

open access: yesPesquisa Agropecuária Brasileira, 2008
O objetivo deste trabalho foi avaliar a eficiência do tratamento de semente de soja com fluquinconazol e da aplicação foliar de fungicidas no manejo da ferrugem-da-soja, em três épocas de semeadura, na safra 2007/2008, em Londrina, PR. O delineamento foi
