Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022-2023: insights from genetic mutations and molecular dynamics simulations. [PDF]
Pest Manag SciPhakopsora pachyrhizi in Paraguay showed diverse resistance to DMI, SDHI, and QoI fungicides at both regional and intra‐field levels, likely driven by target mutation genes. Abstract BACKGROUND Phakopsora pachyrhizi, the causative agent of Asian soybean rust, poses a major threat to soybean production in South America. The rising incidence of fungicide

Characterizing Resistance to Phakopsora pachyrhizi in Soybean [PDF]
Plant Disease, 2011 Resistance in soybean to Phakopsora pachyrhizi, the cause of soybean rust, is characterized by either reddish-brown (RB) lesions or an immune response. The RB type of resistance can be incomplete, as evidenced by the presence of sporulating uredinia within lesions. Susceptibility, on the other hand, is exemplified by tan-colored (TAN) lesions, and can

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

An Immunofluorescence Assay to Detect Urediniospores of Phakopsora pachyrhizi [PDF]
Plant Disease, 2008 An indirect immunofluorescence spore assay (IFSA) was developed to detect urediniospores of Phakopsora pachyrhizi, utilizing rabbit polyclonal antisera produced in response to intact nongerminated (SBR1A) or germinated (SBR2) urediniospores of P. pachyrhizi. Both antisera were specific to Phakopsora spp.

Identifying and Quantifying Phakopsora pachyrhizi Spores in Rain [PDF]
Phytopathology®, 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 ...
