 Abstract
This study was conducted to examine changes in the fungal community on fallen leaves of pear by treatment with lime sulfur. Although the lime sulfur could reduce the primary inoculum of several pathogens on spring season, the effect of lime sulfur has not been well determined scientifically. Fallen leaves infected by pear diseases in pear orchards in Naju were collected and treated with lime sulfur or water as a control. To determine the fungal diversity from each treatment, rDNA internal transcribed spacer (ITS) regions were analyzed after extraction of fungal genomic DNA from lime sulfur-treated or water-treated fallen leaves, respectively. The most common fungal species were Ascomycota and Basidiomycota in both treated leaves. However, the population dynamics of several fungal species including Alternari sp., Cladosporium sp., and Phomopsis sp., which are known as pear pathogens for skin sooty dapple disease, were quite different from each treated leaves. These results indicated that lime sulfur treatment led to changes of fungal communities on pear fallen leaves and could be applicable as a dormant spray.
