An Analysis of the Research on Sugarcane Yellow Leaf: Not a Disease, a Syndrome

Known as a sugarcane disease; sugarcane yellow leaf, or Amarelinho has frightened the growers in Brazil since 1992. However, after undertaking extensive research, the author of the present work has discovered it to be more of a physiological disorder called Autumn Decline. In 2000, a paper advocated the transmission of an associated virus, and the viral etiology became accepted. The author researched the concept of a syndrome instead of an infectious disease for ten years but stopped when he retired and engaged in other interests. In 2021, he searched for the status quo after 30 years of international research. A comprehensive analysis revealed confusing and contradictory results, including those in the article taken as the keynote of viral etiology. However, the research community leniently disregarded that and jumped on the bandwagon. The book aims to disentangle the issue and show that sugarcane yellow leaf (SYL) is not a disease but a syndrome. See more
