Abstract

The huaglongbing (HLB) is devastating citrus disease and cause total yield loss under favorable environmental conditions. The Candidatus Liberibacter species is the cause of citrus greening which is carried on Diaphorina citri during feeding of leaves. In Ethiopia citrus are produced in large commercial and small scale farmers. However, the status of yield reduction has no more attention were given. The bacteria species associated with HLB disease like Ca. Liberibacter asiaticus, Ca. L. africanus and Ca. L. americanus. The vector Diaphorina citri of Ca. Liberibacter asiaticus is heat tolerant and able to adapt temperature above 32°C compared with Ca. L. americanus’ and Ca. L. africanus. The field diagnosis of citrus greening is very difficult tasks and even confusing with symptoms of nutrient deficiency. From all the citrus, HLB is the most destructive and totally decline the production. The typical symptoms of greening disease like asymmetrical blotchy mottling pattern on central leaves, lopsided fruits, bitter tests and greening symptoms only observed in one side of the canopy. Therefore critical diagnosis is important task either the citrus tree has blotchy mottle or leaf yellowing due the deficiency of nutrient or HLB and to recommend disease management options. In present situation the citrus orchards infected with HLB is not be controlled however reducing the vector is possible using insecticides.
