Abstract

The southern blight of Loropetalum chinense var. rubrum is a serious disease which incidences in the cutting beds, and is infected by Sclerotium rolfsii. Its hosts have reached above 20 tree species, with a disease incidence of 27.1% to 96.7%. It damages not only the stock's bases and roots, but also the other sections, and causes soft moist rot or dry rot. It prevailes from June to November and the peak of invasion is from July to August. Its incidence rate is closely related to the practice timethe moisture conditions of the cutting beds. The control could made at the first incidence and the effects of spraying the tree crown with 500-fold solution of kitazin 40EC or 500-fold triadimefon 20EC were over 89.8%.
