Causes

CRLV can be transmitted by nematode (Xiphinema Americana), mechanical inoculation, grafting, or seed (10–20%).^[2]

Symptoms

Leaves become studded with projections or enations between the lateral veins and all along the midrib. As a result, the leaves become deformed and folded, looking very narrow. The face of the leaf has a bumpy texture as a result of the enations on the underside.^{[citation needed]}

Initial infections begin at the lower branches and patches of the tree will show symptoms. Lateral (tree-to-tree) infection is slow and fruit production is reduced. Severe infection may result in the death of the tree.^[3]
