Comments
A lime decline disease has been observed in Al-Hassa region. Symptoms start as leaf yellowing and mottling. Internodes are shortened and branches decline until they become completely dried and necrotic, with no leaves and no fruit production. However, no witches' broom symptoms are observed.
A phytoplasma has consistently been detected in diseased plants, as well as in a leafhopper (Empoasca decipiens) and weeds (Chenopodium murale, Plantago lanceolata and Convolvulus arvensis). But molecular studies suggested that this phytoplasma is distinct from 'Ca. P. aurantifoliae' (98-99% identity).
