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

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 ...

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

Fungicide Spraying Programs Reducing Asian Soybean Rust Impact on Soybean Yield Components
Journal of Agricultural Science, 2022 Soybean is one of the leading agricultural commodities, and Brazil is currently the largest producer globally. Despite this, fungal diseases as Asian Soybean Rust (ASR) are among the primary limiters of high crop yields in Brazilian fields. Losses caused by the biotrophic fungus Phakopsora pachyrhizi can reach up to 90%, depending on weather conditions,

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.

Asian Soybean Rust Sentinel Plots
, 2006 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.

Asian Soybean Rust Severity Sowed in Different Seasons
Journal of Agricultural Science, 2020 In on-farm trials, the foliolar severity of Asian soybean rust was evaluated in 44 areas, in three regions of Mato Grosso sown in December (2019) and February (2020). Several susceptible cultivars were used in different crop systems; insect pests and weeds were controlled with different management systems by the farmers.
