Ferrugem-asiática da soja no Brasil: passado, presente e futuro

摘要: Asian soybean rust, caused by the fungus Phakopsora pachyrhizi , is most severe disease of crop and can cause yield losses up to 90%. The was first reported in Brazil 2001. Epidemics are common country, where survive year‑round. Regulatory measures reduce inoculum between seasons avoid late-season have been adopted manage disease. Disease control has relied mainly on chemical control, but a lower sensibility fungicides Brazil. Major‑resistance genes mapped incorporated into cultivars. With reduced efficacy fungicides, adoption integrated will be important for sustainability crop. This review presents main changes system introduction Brazil, current management strategies losses, new trends that, together with biotechnological strategies, improve future.
