Abstract:

A new leaf disease occurs in chestnut-producing areas of Tai'an and Linyi in Shandong Province. Brown spots of 2-3 mm were formed on the infected leaves at initial stage. With the rapid expansion of lesions,the center of spots turned yellow cinnamon and had dark brown on edge. The diseased leaves showed irregular dry rot in a large area at the same time, which seriously influenced the tree vigor and yield.This disease was identified as a new leaf disease with the pathogen morphology and molecular biological characters, named as brown margin leaf blight. The isolate BY1 was found to be a kind of pathogenic strain of Phomopsis castaneae-mollissimae by pathogenicity test.

Key words: brown margin leaf blight of C. mollissima, symptoms, disease identification
