摘　　要：[Objectives]The paper was to evaluate the effectiveness of Xiulijing in the management of rust in Golden Delicious apple cultivation.[Methods]The Golden Delicious apple was utilized as the test material.During the young fruit stage,various dilutions of Xiulijing were applied,specifically at concentrations of 200,400,600,800,1000,and 2000 times.Additionally,both the application of a 3000-fold dilution of GA 4+7 and the practice of fruit bagging were designated as the control treatments,while a water spray was utilized as the blank control.The fruit rust index and the incidence of rust-infected fruits were evaluated to assess the effectiveness of control measures for fruit rust in Golden Delicious apple cultivation.[Results]The application of Xiulijing,with dilutions ranging from 200 to 2000 times,exhibited a significant impact on reducing both the fruit rust index and the incidence of rust-infected fruits in Golden Delicious apples.The application of a 1000-fold dilution of Xiulijing resulted in a statistically significant reduction in both the fruit rust index and the incidence of rust-infected fruits,with reduction rates of 21.1%and 31.5%,respectively.Among the various strategies for the prevention and control of apple rust,fruit bagging emerged as the most effective method.The other two technical measures demonstrated significant control effects;however,no substantial differences were observed between them.[Conclusions]The biological control agent Xiulijing is more deserving of promotion and application in practical production due to its significantly superior economic benefits,safety,and stability.
