Parad  M. & Rezaei R. 2015. Citrus greening  disease. Plant Pathology Science 5(1):37-47.

Citrus greening or Huanglongbing, is one of the most devastating disease of citrus worldwide. It is common in the southeast of Asia and is also recently reported from south provinces of  Iran. It is caused by Liberibacter sp. that tend to colonize in phloem vessels of the host. This bacterium affects all of the main types of citrus plants and reduces fruit production. One of the identifying challenges is that some of the disease symptoms are similar to deficiency of some nutrient such as zinc. The most important vectors of the disease causal agent are some psylla species. The only worthwhile control measure is removing the microbial inoculums from the affected tissues. Management of the disease described in this paper.

Azadvar M, Alizadeh HR, Najafinia M, Safarnejad MR  and  Esfandiari S (2019) Citrus sudden decline disease in the south of Kerman province. Plant Pathology Science 8(2): 31-37. DOI: 10.2982/PPS.8.2.31
 
During recent years, the newly emerging disease, citrus sudden decline (CSD) has destroyed many of citrus trees grafted onto bael rootstock in the south of Kerman Province. The disease is caused by Candidatus Liberibacter asiaticus and its simultaneous infection to soil born pathogens or Ca. Phytoplasma aurantifolia, or heat and drought stresses can increase the disease severity and appearance of the decline symptoms. Using the healthy and certified rootstock, using the Sour Orange or Volkamer Lemon as rootstock, control of the sucking insects at the time of flushing, optimum irrigation with appropriate distribution especially during the summer season, control of soil born fungi and nematodes, avoiding stress to plant and appropriate pruning are recommended for prevention and management of CSD disease in the south of Kerman Province.
