The invention relates to a physalospora piricola nose resistance identification method, in particular to a method for rapidly identifying resistance of apple branches and trunks to the physalospora piricola nose. The physalospora piricola nose is inoculated to a PDA culture medium to be cultured so that a physalospora piricola nose culture medium bacterial colony can be obtained; pseudo identified varieties or rootstock young sprout leaves without plant diseases or insect pests at the top end, the front faces of the leaves are stabbed by an inoculating needle, and then the physalospora piricola nose is inoculated; after the bacteria-bearing leaves are cultured for six days, the diameters of disease spots of the leaves are measured according to a crossing method, the disease spot area of the leaves are worked out and compared with the disease spot areas of known resistance grade materials, and the grade of resistance of varieties to be identified or rootstocks to the branch and trunk physalospora piricola nose is determined. According to the method for rapidly identifying the resistance of apple branches and trunks to the physalospora piricola nose, leaves are inoculated, infection conditions suitable for the physalospora piricola nose are created, physalospora piricola nose resistance identification is performed on the infection result, few identification materials are needed, identification time is short, repeatability is high, and the identification method is simple, easy to master and popularize, and low in cost.
