Abstract
In 2009, a new citrus viral disease caused by citrus yellow vein clearing virus (CYVCV) was first discovered in China, and now CYVCV is widely distributed in the field. CYVCV is transmissible by grafting and is spread by aphids from lemon to bean, and from bean to bean. However, whether CYVCV is transmitted by contaminated tools is unknown. In this study, the transmissibility of CYVCV with contaminated knife blades was investigated in sour orange and rough lemon. Three months after knife blade inoculation, CYVCV was detected in 16.5% of sour orange and 20.0% of rough lemon, respectively. Furthermore, six months post inoculation, the presence of CYVCV in sour orange and rough lemon was 23.3 and 20.0%, respectively. The results indicated that CYVCV is transmitted from citrus to citrus by contaminated knife blades.
