Abstract: Using tools such as Excel, VOSviewer, and Citespace, a knowledge map was constructed to conduct qualitative and quantitative analysis of literature on grape gray mold from 1990 to 2024 in the CNKI and WOS databases. The results indicate a growing trend in the number of publications, reflecting sustained increases in both attention and research activity in this field. Despite the formation of a core author group, collaborative efforts among these researchers remain limited. Among domestic institutions, Northwest A&F University leads in the number of publications, while internationally, the French Research Institute for Agriculture, Food and Environment(INRAE) leads in publication volume, total citations, and average citations. The core journal in CNKI is Sino-Overseas Grapevine & Wine, whereas in WOS, it is Postharvest Biology and Technology. In terms of international collaboration, contributions from China, the United States, and Italy are particularly significant. From the perspective of disciplinary distribution, Plant Protection dominates in CNKI, while Food Science and Technology leads in WOS, with Horticulture ranking second in both. Current research primarily focuses on resistance identification, screening of antagonistic microorganisms,and evaluation of chemical efficacy.The bibliometric analysis results contribute to a comprehensive understanding of research hotspots and trends in grape gray mold, and can provide references for future studies.
