Contents
Causes
CRLV can be transmitted a nematode, Xiphinema americana; mechanical inoculation; transmitted by grafting; transmitted by seed (10–20%).
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.
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.
