POTENTIAL DISTRIBUTION ZONES FOR SOYBEAN RUST (Phakopsora pachyrhizi) IN MEXICO

Ecosistemas y Recursos Agropecuarios, 2015
Asian Soybean Rust is one of the most important soybean diseases. Since the past decade, some im- portant soybean production areas in America, like Brazil and the United States of America, have been affected by this disease.

Alternative products on the control of asian rust soybean

Research, Society and Development, 2021
In recent years, it has been observed a significant expansion of the organic market. In this context, the main phytosanitary problem of soybean in the organic system is Asian rust (Phakopsora pachyrhizi), for which it is difficult to control, considering the restriction of products authorized for use in the organic system and the limitation of research

Induction of resistance and chemical management of mildew and Asian rust in soybean cultivation

Acta Agronómica, 2021
Soybean (Glycine max (L.) Merrill) is one of the most cultivated in Brazil and has lost productivity due to the attack of disease pests. Thus, it is necessary to develop new technologies capable of reducing damages caused by such biological agents.

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.

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 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

Asian soybean rust control in response to rainfall simulation after fungicide application

Acta Scientiarum. Agronomy, 2020
Asian soybean rust (Phakopsora pachyrhizi) is the main disease that affects soybean in Brazil. Fungicide applications are the main control method, but they can be influenced by the occurrence of rain.
