Zucchini yellow mosaic virus (ZYMV) is an aphid-borne virus that causes yield losses and fruit quality defects in cucurbit crops. ZYMV infects all cultivated cucurbit types including cucumber, pumpkin, rockmelon, squash, watermelon and zucchini. It does not infect other horticultural crops.

What does yellow mosaic virus do?

Zucchini yellow mosaic virus (ZYMV) is an aphid-borne virus that causes yield losses and fruit quality defects in cucurbit crops. ZYMV infects all cultivated cucurbit types including cucumber, pumpkin, rockmelon, squash, watermelon and zucchini. It does not infect other horticultural crops.

How can we control yellow mosaic virus?

Control measures: — Infected plants should be removed. — Remove and destroy disease-affected leaves/plants from crop fields to avoid secondary spread. — Destroy host weeds. Intercrop with non host crops like sorghum, pearl millet and maize.

How is yellow mosaic virus transmitted?

The virus is transmitted by over 20 species of aphids (e.g., the pea, green peach, and bean aphids). Transmission of the virus to the bean plant occurs within seconds once virus-carrying aphids begin feeding on the crop. Aphids can effectively spread the virus within a field, resulting in high rates of infection.

The veins of the leaves will be cleared by the virus and intervenal area becomes completely yellow or white.

How fast does mosaic virus spread?

Comments on the Disease Cucumber mosaic virus is spread from plant-to-plant by many species of aphids. Aphids only retain the ability to transmit these viruses for very short periods of time (minutes to a few hours). Thus, spread is often very rapid and local.
