Severe blight of grapevine found in the EU (IT)
A new severe disease of grapevine has been found in Sicily (EU). The disease called grapevine blight is caused by Nattrassia toruloidea (synonym: Hendersonula). Symptoms appear on grapevine leaves in form of scattered chlorotic spots which later necrotize. Removal of bark near wounds reveal dark alterations of the cambium. It was observed that infected vines defoliated and that the shoots dried from the apex. A rapid evolution of the disease has been observed which leads to death of the entire grapevine within a period of 2-3 years.
