Current Situation and Research Prospect of Rhizome Rot and Stem Rot of Sacha Inchi （Plukenetia volubilis） in China

Sacha inchi（Plukentia volubilis）, native to the Andes Mountains of South America, including Peru and Ecuador, is an important oilseed crop in the local area.The sacha inchi was introduced into China and popularized in 2006. However, it was found that with the increase in sach inchin planting years, rhizome rot, leaf yellowing and falling off occurred, which seriously affected the yield and continuous promotion of sacha inchi. This article summarized the research on root and stem rot disease of sacha inchi, analyzed the causes for root and stem rot, providing theoretical reference and technical support for the sustainable development of the sacha inchi industry.To provide a theoretical reference for the prevention of rhizome rot and the improvement of yield.
