Abstract:Soybean sclerotinia is widely distributed and is a type of soybean disease found worldwide. In the Northeast region of China, the incidence rate of soybean sclerotinia disease can reach over 60%, severely affecting soybean yield and economic benefits. Therefore, studying the pathogenic principle of the soybean sclerotinia disease pathogen—Sclerotinia sclerotiorum, as well as effective detection and identification methods, has become an urgent issue in China"s soybean industry. This article reviews the pathogenic mechanism of Sclerotinia sclerotiorum at the molecular level and reviews. It reviews the existing detection methods for the fungus: traditional detection methods, serological detection methods, and molecular biological [1]detection methods, among others. It details the sensitivity, specificity, and applicability of the existing detection methods, compares and evaluates the advantages and limitations of various methods, and provides an initial exploration into the detection model for soybean sclerotinia. This study aims to provide a reference for the identification and detection of soybean sclerotinia disease, to offer technical support for the early detection of the disease, and to provide some theoretical basis for the healthy development of the soybean industry.
