control of fungal diseases of trees and shrubs at Lanzhou Wuquanshan Park

The fungal diseases of some trees and ornamental shrubs in Lanzhou Wuquanshan Park were investigated from the summer to the autumn in 2008 and 2009. The results showed that there were 32 fungal diseases caused mainly by imperfect fungi and Ascomycetes, in which 20 diseases were found on the trees, and 12 on the ornamental shrubs. Most of them occurred on Salicaceae and Rosaceae plant leaves. The quarantine and biological control for the pathogens and reasonable agricultural technologies for the plants maintenance should be effective measures to prevent the spread of fungal diseaces.
