doi:10.11924/j.issn.1000-6850.casb2024-0657

Abstract

Abstract:

Konjac (Amorphophallus konjac) is favored because of its outstanding nutritional value and medicinal value, and the market demand has been increasing year by year. However, konjac is often affected by soft rot in the process of planting, which seriously affects its yield and quality, and restricts the sustainable development of konjac industry in China. This paper focuses on the research progress of the pathogen, pathogenesis, symptoms and control methods of konjac soft rot, and analyzes the advantages and disadvantages of different control methods in practical application. In view of the key research direction of konjac soft rot in the future, it is proposed that the breeding of high-quality disease-resistant varieties of konjac should be carried out in an all-round way; the pathogenic mechanism of konjac soft rot should be strengthened; the research on the structure and diversity of rhizosphere soil microbial community should be strengthened; and the comprehensive prevention and control system of konjac soft rot should be established and improved, so as to provide theoretical reference for the prevention and further research.

Key words: Amorphophallus konjac, soft rot, control measures, research progress
