Impact of fungicides on Asian soybean rust management in South American producing countries: a systematic study

Asian soybean rust (ASR), caused by the fungus Phakopsora pachyrhizi, significantly reduces crop yield and leads to increased costs associated with fungicide application. A comprehensive literature review was conducted covering the period from 2000 to 2023, focusing on articles related to Phakopsora pachyrhizi in the MERCOSUR region (including Argentina, Brazil, Paraguay, and Uruguay). This systematic review compiled findings from 474 scientific articles, examining publication trends, authorship, countries, citations, and research topics. Key topics included genetic mutations in the describedorganisms, control efficiency data to assess trends in fungicide efficiency, and areas under the disease progress curve. Since 2005, the number of publications has doubled, with Brazil leading the research. The review highlights the growing prevalence of mutations in P. pachyrhizi, which contribute to reduced fungicide efficacy and increased resistance.
