Relationship between biochemical and photosynthetic traits with Asian soybean rust [PDF]
Asian soybean rust (Phakopsora pachyrhizi - ASR) is one of the major diseases that occur in soybean and causes great damage to commercial crops. Therefore, the goal of this work was to investigate the relationship between biochemical and photosyntetic parameters in soybean with ASR.

Severity and control of asian rust in soybean crop
A ferrugem asiática causada pelo fungo Phakopsora pachyrhizi Sydow & Syd foi identificada no Brasil na safra 2000/01, no Estado do Paraná. Atualmente já se encontra disseminada em grande parte do território nacional. Esta doença tem causado elevadas perdas de produtividade na cultura da soja, sendo maiores os prejuízos em infecções precoces.

On the current status of Phakopsora pachyrhizi genome sequencing
Recent advances in the field of sequencing technologies and bioinformatics allow a more rapid access to genomes of non-model organisms at sinking costs. Accordingly, draft genomes of several economically important cereal rust fungi have been released in ...

Asian Soybean Rust Sentinel Plots
Asian soybean rust (SBR) caused by Phakopsora pachyrhizi was discovered for the first time in the continental United States in November 2004. It was known that under the right conditions, this pathogen could spread rapidly and cause severe yield losses.

Relationship between soybean plant defoliation and Asian soybean rust severity [PDF]
ABSTRACT Data from experiments conducted in the field with eight fungicide mixtures added of five mancozeb levels were used to generate gradients of soybean rust severity, plant defoliation, and soybean grain yield. The data were subjected to correlation analysis between defoliation and severity, defoliation and grain yield, and grain yield and rust ...

Application of prediction models of asian soybean rust in two crop seasons, in Londrina, Pr
Predictive models of Asian soybean rust have been described by researchers to estimate favorable responses to epidemics. The prediction strategies are based on weather data obtained during period when initial symptoms of the disease are observed ...
