Quantitative Resistance to Quinone Outside Inhibitor (QoI) Fungicides in Puccinia horiana Through the Combination of Seven Distinct Substitutions in Cytochrome b

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Puccinia horiana, the causal agent of chrysanthemum white rust, has developed quantitative resistance to QoI fungicides through one to four substitutions, selected from F90I, N256S, Y257N, L275F, F278L, M295V or L299F in cytochrome b (Cytb). ABSTRACT Quinone outside inhibitors (QoIs) are a major class of agricultural fungicides.

Quantifying ENSO‐Mediated Shifts in Soybean Rust Impact: Yield Loss Dynamics and Management Implications in Brazil

Plant Pathology, Volume 74, Issue 9, Page 2980-2988, December 2025.
Meta‐analysis of 417 trials shows that El Niño amplifies soybean rust impacts in Brazil. Damage coefficients were higher during El Niño, causing greater yield losses at similar severity, whereas yield protection from management was also greatest, emphasising the value of El Niño‐informed disease outlooks.

Characterization and Quantification of Fungal Colonization of Phakopsora pachyrhizi in Soybean Genotypes [PDF]

Phytopathology®, 2014
Soybean rust, caused by the fungus Phakopsora pachyrhizi, is an economically important disease of soybean with potential to cause severe epidemics resulting in significant yield losses. Host resistance is one of the management tools to control this disease.

A new chitinase-like xylanase inhibitor protein (XIP) from coffee (Coffea arabica) affects Soybean Asian rust (Phakopsora pachyrhizi) spore germination

BMC Biotechnology, 2011
Background Asian rust (Phakopsora pachyrhizi) is a common disease in Brazilian soybean fields and it is difficult to control. To identify a biochemical candidate with potential to combat this disease, a new chitinase-like xylanase inhibitor protein (XIP)

Development of a host-induced RNAi system for the control of Asian Soybean Rust Phakopsora pachyrhizi

, 2015
Phakopsora pachyrhizi, the causal agent of Asian Soybean Rust is a devastating plant pathogen that can cause significant yield losses in soybean production. So far, Phakopsora pachyrhizi is controlled by the use of fungicides and cultivation practices. A

First Report of Phakopsora pachyrhizi on Soybean Causing Rust in Tanzania

Plant Disease, 2014
Phakopsora pachyrhizi Syd. was reported on legume hosts other than soybean in Tanzania as early as 1979 (1). Soybean rust (SBR), caused by P. pachyrhizi, was first reported on soybean in Africa in Uganda in 1996 (3), and its introduction into Africa was proposed to occur through urediniospores blowing from western India to the African east coastal ...

Hourly and daily changes on airborne urediniospores of Phakopsora pachyrhizi

Bioscience Journal, 2019
The Asian rust (Phakopsora pachyrhizi) is one of the most destructive diseases of soybean in Brazil. Despite its importance, little is known about the airborne inoculum production dynamics of pathogen throughout the soybean cycle in Brazil. The objective of this study was to assess the temporal variation of air collected P.
