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.

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.
