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.

Does cucumber mosaic virus affect tomatoes?

Tomatoes infected with the cucumber mosaic virus develop a slight yellowing and mottling of the older leaves. Expanding leaves typically become twisted, curl downward, and develop a “shoestring” appearance as a result of a restriction of the leaf surface to a narrow band around the midrib of the leaf.

What causes rose mosaic?
