| Mosaic has
been observed in the eastern and western growing regions of
the United States and Canada.
Symptoms
Leaves on one or more branches show mild
to brilliant mottle or mosaic patterns of yellow, pink,
or yellow-green. Symptoms are not produced every year and
presumably depend on sunlight intensity. Fruit on diseased
bushes ripens late and is of poor quality.
Disease cycle
No causal organism or vector has been identified,
although a virus is suspected. The disease spreads slowly
from bush to bush. |
