Virulence Diversity of Phakopsora pachyrhizi in Mexico

PhytoFrontiers, 2022
Asian soybean rust, caused by the pathogen Phakopsora pachyrhizi, is the main soybean disease in Mexico and worldwide, threatening its production. Knowledge about the virulence of Mexican rust populations (MRPs) is crucial to develop or introduce soybean

Characterization of Nonhost Resistance of Arabidopsis to the Asian Soybean Rust [PDF]

Molecular Plant-Microbe Interactions®, 2008
Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is a devastating disease of soybean. We report the use of the nonhost plant Arabidopsis thaliana to identify the genetic basis of resistance to P. pachyrhizi. Upon attack by P. pachyrhizi, epidermal cells of wild-type Arabidopsis accumulated H2O2, which likely orchestrates the frequently ...

Potential of thaxtomin A for the control of the Asian soybean rust

Canadian Journal of Plant Pathology, 2021
Several strategies are required to achieve satisfactory control of Asian soybean rust (ASR) caused by the fungus Phakopsora pachyrhizi. The use of resistance inducers represents a helpful alternative for management of this disease, since they can present good results when included in an integrated ASR management programme.

Characterization of three soybean landraces resistant to Asian soybean rust disease [PDF]

Molecular Breeding, 2020
AbstractPhakopsora pachyrhizi is an obligatory biotrophic fungus that causes Asian soybean rust (ASR) disease. ASR control primarily involves chemical control and the use of resistant soybean cultivars carrying an Rpp (resistance to P. pachyrhizi) gene. This study aimed to characterize the ASR resistance of three soybean Asian landraces.

Asian Soybean Rust Resistance: An Overview [PDF]

Journal of Plant Pathology & Microbiology, 2015
Asian soybean rust caused by Phakopsora pachyrhizi, occurs in all soybean production regions of the world. Rust is the most destructive foliar disease of soybean and can cause yield losses of over 80%. To date, six race-specific resistance genes have been identified in plant introductions. However, races of P. pachyrhizi able to overcome the resistance

Relationship between biochemical and photosynthetic traits with Asian soybean rust [PDF]

Anais da Academia Brasileira de Ciências, 2018
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.

EFFICIENCY LOSS OF RECORDED FUNGICIDES FOR THE CONTROL OF ASIAN SOYBEAN RUST IN CENTRAL REGION OF BRAZIL

Revista de Agricultura Neotropical, 2016
Due to grower allege of low efficiency of triazole fungicides in recent years in Central Brazil on the control of Asian soybean rust (Phakopsora pachyrhizi), this study was undertaken to demonstrate the efficiency loss of products registered for rust and

Severity and control of asian rust in soybean crop

, 2021
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.

Relationship between soybean plant defoliation and Asian soybean rust severity [PDF]

Summa Phytopathologica, 2019
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 ...

Association of hydrogen peroxide with commercial fungicide formulations in the control of Asian soybean rust

Ciência Rural, 2021
: In recent years, there have been reductions in the efficacy of the fungicidal control of Phakopsora pachyrhizi, thereby hindering the management of soybean rust and compromising crop yield.
