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.

First Report of Phakopsora pachyrhizi on Soybean in Costa Rica

Plant Disease, 2015
Phakopsora meibomiae (Arthur) Arthur has been reported to occur in several legume species in the tropical regions of Central and South America. In Costa Rica, this pathogen was initially reported as P. pachyrhizi Sydow (1); however, to our knowledge, P. pachyrhizi has not been detected in Costa Rica.

Transcriptome Profiling of Resistance Gene Analogs in Soybean's Cross‐Tolerance to Water Limitation and Rust Stress

Food and Energy Security, Volume 14, Issue 5, September/October 2025.
ABSTRACT Asian soybean rust (ASR), caused by Phakopsora pachyrhizi, is the most destructive foliar disease of soybean, with yield losses up to 90%. With climate change intensifying drought and expanding disease incidence, it is critical to understand how combined abiotic and biotic stresses influence plant defense.

Winter Survival of the Soybean Rust Pathogen, Phakopsora pachyrhizi, in Florida [PDF]

Plant Disease, 2008
Soybean rust (SBR) survival and host availability (kudzu, Pueraria spp.) were assessed from November 2006 through April 2007 at six sites from the panhandle to southwest Florida. Micro loggers recorded both temperature and relative humidity hourly at each location.

Soybean Rust Resistance and Yield Performance of Elite Soybean Genotypes Across Diverse Environments in Uganda [PDF]

Plant Environ Interact
ABSTRACT Soybean (Glycine max (L.) Merr.) is one of the important legumes globally, serving as an affordable and valuable protein source for humans and livestock. However, selecting the most suitable genotype across diverse environmental conditions remains a major challenge due to significant genotype‐by‐environment interactions (GEI). In addition, the
