Research Progress in Controlling Root Rot in Sugar Beet

Abstract

Root rot poses a significant threat to sugar beet crops worldwide, making it a major concern in beet-growing regions. This study aimed to summarize the common causal organisms of sugar beet root rot and focus on identifying root rot pathogen populations, discovering germplasm resources discovery, and breeding resistance against major causal organisms. Additionally, the research progress on chemical and biological control methods for sugar beet root rot is discussed. In order to improve the resistance of sugar beet to root rot and obtain germplasm resources with high resistance to root rot, multidimensional collaboration strategy is recommended; implementation of pathogen population monitoring should be prioritized to identify predominant pathogenic fungi and elucidate their pathogenic mechanisms within cultivation zones, thereby providing scientific basis for targeted breeding of resistant cultivars; disease management systems require integration of synergistic applications between chemical and biological control agents to establish integrated management protocols; during breeding processes, molecular marker-assisted selection (MAS) technology should be incorporated to pinpoint disease resistance loci and optimize breeding efficiency; concurrent emphasis should be placed on evaluating the application potential of emerging biotechnological tools, which may overcome limitations inherent in conventional breeding methodologies.
