Cucumber Mosaic Virus

Cucumovirus CMV · virus · also: CMV

Issue type
disease
Seedborne
No
Resistance code
CMV
Affects
Pepper, Tomato, Cucumber, Melon

Symptoms

Narrow strap-like leaves, mosaic mottling, and ring patterns on fruit. One of the widest host ranges of any plant virus, which makes weed hosts a permanent reservoir.

Management

Weed management around field edges matters more than spraying, because dozens of aphid species transmit it non-persistently. Partial resistance exists in some pepper lines; complete resistance does not.

Varieties with documented resistance

No commercial varieties in the database carry documented resistance to this issue, management is cultural and (for seedborne pathogens) starts with tested, certified seed.
