Zucchini Yellow Mosaic Virus
摘要
Zucchini yellow mosaic virus (ZYMV) is a plant virus that primarily affects zucchini and other cucurbit crops. ZYMVis classified as a Potyvirus belonging to the family Potyviridae. It causes significant economic losses in cucurbit production worldwide and is transmitted by aphids in a nonpersistent manner through seed and mechanical means. After infection to the plants, it leads to a range of symptoms that can severely affect plant health and fruit production. The symptoms of ZYMV infection include mosaic patterns of leaf yellowing, leaf distortion, stunted growth, and reduced fruit quality. Infected fruits may exhibit discoloration, mottling, and deformities, rendering them unmarketable. Yield losses due to ZYMV can be substantial, affecting both commercial and small-scale farmers. The management of ZYMV involves a combination of preventive measures and control strategies including the use of resistant cultivars, cross protection, cropping systems, removal of weed hosts and the application of chemicals. Additionally, the early detection and removal of infected plants can help prevent the further spread of the virus.
