Zucchini Yellow Mosaic Virus
Zucchini Yellow Mosaic Virus (ZYMV) is an aphid-borne potyvirus and is regarded as a major pathogen of cucurbits.
It affects pumpkins, squashes, vegetable marrows, courgettes, melons, watermelons, cucumbers, gherkins, and various gourds especially zucchinis. The effects are severe leaf mosaic, yellowing and eventually the leaves show “shoestring” symptoms. Fruits can become stunted, twisted and deformed by raised protuberances, which make them unmarketable.
Infection may be spread through infected seed and thus getting clean seed is very important to prevent the disease. To control the spread of the disease insecticides are used.
