Produces more necrotic symptoms than in cymbidiums; dark brown or black sunken rings or streaks which tend to coalesce darkening the whole leaf; the symptoms generally are more pronounced on the upper surface of the leaf and on the lower leaves of the plants; the virus is in the flower but no virus-induced color-breaking occurs.

Cymbidium Mosaic Virus Comments
CYMBIDIUM MOSAIC VIRUS: Characteristics Very common in cymbidiums, less so in cattleyas and hybrids, and in phalaenopsis, epidendrum and oncidium; certain lines are infected world-wide; symptoms are highly variable; it usually begins in the new shoots and shows as chlorotic patches and flecks; on maturation the shoots become increasingly chlorotic and later necrotic; in the flower parts it shows no symptoms. OD58-149, S208 0
CYMBIDIUM MOSAIC VIRUS: Description Lesions are always elongated, sometimes streak-like, are often whitish for a month or two before turning brown-grey or black and are usually slightly sunken. A82-37; place cutting tools, etc., in the oven at 114 dF to kill CMV. OA81-152 0
CYMBIDIUM MOSAIC VIRUS: Most Common Virus Disease Cymbidium Alexanderi 'Westonbirt' is infected in all its divisions; small elongated chlorotic streaks appear on the younger leaves; later widen and elongate and become sharply defined some with islands of green; necrosis shows as black streaks usually in the older leaves causing death in many cases; early mottling sometimes lessens later; mildly infected plants produce flowers adequately. B43+, BU52+ 0
CYMBIDIUM MOSAIC VIRUS: Symptoms and Spread Leaf mosaic, chlorosis, streaks or necrotic spots are visual in nature but in many plants no foliage symptoms appear; the number and size of flowers are reduced; there is no color-breaking in cymbidiums or dendrobiums; there is flower necrosis in cattleyas; 70 percent of 60 hybrid dendrobiums tested in Bangkok have it.
