Abstract:
The diseased fruits of blueberry postharvest disease in Majiang county were used as test materials,and the biology of pathogens was identified by morphological and rDNA-ITS sequence comparison.The indoor toxicity of different fungicides to the main pathogenic bacteria of blueberry was studied in order to provide some reference for the prevention and control of postharvest diseases of blueberry in Majiang.The results showed that six kinds of fungi were responsible for fruit rot of blueberry,which were Botrytis cinerea,Penicillium,Pestalotiopsis cocculi,Xylaria sp.,Trichoderma longibrachiatum,and Sordariomycetes sp..Among them，Botrytis cinerea,Penicillium,Pestalotiopsis cocculi were the dominant pathogen.Prochloraz showed good inhibitive effect against Penicillium.The EC50 values of this fungicide to Penicillium was 0.007 9 μg?mL-1,which could be used as an effective control agent for blueberry postharvest disease in the field.
