Characteristics of fungicide resistance in Asian soybean rust (Phakopsora pachyrhizi) in Paraguay for 2022–2023: insights from genetic mutations and molecular dynamics simulations

open access: yesPest Management Science, EarlyView.
Phakopsora 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
