Abstract

Main pathogen of dongzao disease is Alternaria Nees ex wallr by separating and identifying.The opti-mal combination determinated by trend surface analysis was based on inhibition of chitosan and ozone against sporula-tion of the pathogen and wounded-inoculated experimentation of dongzao was studied.The results indicated that the optimal effect on inhibition of sporulation of the pathogen was 1.25 mg/mL chitosan and 323 ug/L ozone.0.75 mg/ mL chitosan combining 323 ug/L ozone could reduce decaying rate of dongzao fruit and could reduce the growing rate of the decayed area.

Key words： chitosan; ozone; pathogen; disease; suppression
