Alarm on the Rapid Increase in Distribution of Cucumber Green Mottle Mosaic Virus in China

Cucumber green mottle mosaic virus (CGMMV) is becoming a major threat to cucurbit crop production and so listed as the quarantine pathogen in many countries. China, as a large crop producing country, can suffer considerable economic loss from virus dissemination and infection. On account of this situation, our paper lies attention on: a. temporal viral distribution, risks and trend of CGMMV in China; b. possible reasons for rapid dissemination; c. available measures for virus control, especially those in phytosanitary category. In order to limit CGMMV dissemination, quarantine of host plant tissues or seeds needs to be further intensified before transportation or even flowing between different countries.
