western striped and 12-spotted cucumber beetles,
but not by pollen.
Strawberry Mild Crinkle
Caused by Strawberry Vein Chlorosis Virus with
or without Strawberry Mottle Virus.
Squash (Southern) Mosaic
On squash in Florida, infecting also cucumber
and watermelon.
Strawberry Mild Yellow Edge Chlorosis
Potexvirus
Stock Mosaic
Slight chlorosis of leaf margin.
On stock, reported from California. Definite mot-
tling with dark green islands conspicuous against
light green areas. Plants are stunted; seed pods
small; flowers broken with petals undersized.
Cut-flower fields are often a total loss, but there
are resistant varieties.
Strawberry Mild Yellow Edge
Luteovirus
Transmitted by aphids in persistent manner.
The relation to Soybean Dwarf Luteovirus
is so close that
they are probably the same
species.
Strawberry Crinkle Cytorhabdovirus
Strawberry Mottle
Chlorotic and necrotic spotting with crinkled
leaves and vein clearing. Transmission by straw-
berry aphid.
Chlorotic spotting, leaf distortion.
Strawberry Latent Ringspot Nepovirus
Strawberry Multiplier Disease
Infects strawberry and rose; latent and seedborne
in parsley.
Resembling witches' broom and stunt; transmit-
ted by leaf grafting.
Strawberry Latent Virus Rhabdovirus
Strawberry Necrotic Shock ¼ Tobacco
Streak Ilarvirus
Causing no distinct symptoms but intensifying
those caused by other viruses.
Blackish spots on leaves and petioles; whole
crown may be killed, but plants recover, and
virus becomes latent.
Strawberry Leaf Curl
Caused by Strawberry Veinbanding Caulimovirus
plus Strawberry Latent Rhabdovirus.
Strawberry Pallidosis ¼ Cucurbit
Yellows Crinovirus and Beet
Pseudo-Yellows Closterovirus
Strawberry Leaf Roll
Leaflets are rolled down, pale green, small, on
spindly petioles.
On strawberry.
