“…Results showed that CBLVd were detected in Citrofortunella microcarpa, C. aurantiafolia, C. hystrix, C. maxima and C. sinensis but not in C. reticulata . The findings suggested that citrus could be a natural host to CBLVd (Eiras et al 2013; Hammond and Owens, 2006). CBLVd was detected in Johor, Malacca and Selangor suggested that infected citrus plant materials could be the source of CBLVd dissemination.…”

12 A 328 nucleotide (nt) variant of Citrus bent leaf viroid (CBLVd) was characterized from citrus 13 varieties in Malaysia showing leaf bending, stunting and midvein necrosis. CBLVd was 14 detected by RT-PCR assay using CBLVd specific primers in 12 out of 90 samples, collected 15 from six different areas in Malaysia. The viroid was present in five species of citrus namely 16 Citrofortunella microcarpa, Citrus aurantifolia, C. hystrix, C. maxima and C. sinensis.

“…Furthermore, it causes stem pitting in the grafting region and a reduction in fruit size and production [14]. This virus is transmitted by infected propagating material and aphids [2,5,[8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Aphids are a significant role in transmission to remote distances.…”

“…The symptom of this disease is a dotted or continuous line of orange-yellow discoloration associated with projections or bark pegs on the inner bark surface and corresponding pits in the wood at the bud union [24,15,27,49]. Sometimes, this disease causes the infected tree to decline and die or remain stunted.…”

Citrus are cultivated in a vast area worldwide and many countries grow it. Citrus fruits are delicious and everybody can eat it easily so many farmers like to grow them because of the good market. This plant has many diseases that induce various kinds of agents like fungi, bacteria, nematodes, and viruses. In this chapter, we discussed some citrus viral diseases that are very important and dangerous for fields. First, the Citrus Tristeza virus is explained that exists around the world. After that, you will know about other viruses like the Citrus psorosis virus. Viroids are another agent that causes diseases and reduces the amount of production. You learn some of them in this chapter like Hop stunt viroid, Citrus exocortis viroid, etc. The significant point of knowing citrus viral diseases is in the management of diseases. The control of viral diseases is difficult because there are no poisons or combinations to remove viruses from infected plants. If farmers or experts know about symptoms that cause viruses or viroids, they can report it to the related office and do some work to control it and it is important to the agriculture industry.

“…These are transmitted directly and through propagation [71]. Stunting, dwarfing, bark cracking, yellowing of leaves, backward leaf bent, pin holing, yield loss and ultimately tree decline are the common symptoms of citrus viroid diseases [63,71,72]. Citrus viroids alone or with other viruses or prokaryotes in the host contribute considerably in tree decline [73].…”

Citrus is a highly nutritive and prized fruit crop around the world. It contributes a substantial share in local consumption and exports of a nation to earn a handsome foreign exchange. The production of citrus is under the threat of citrus decline. Different factors are responsible for the citrus decline but virus and virus-like diseases have the major role in this decline. Virus and virus-like diseases alone or in association with other biotic and abiotic factors exist in the citrus orchards. Therefore, indexing of diseases caused by virus and virus-like pathogens is the key factor to manage these citrus diseases. Proper facilities and skilled personnel are the pre-requisite for the diseases indexing procedures. Biological, serological and molecular indexing is sensitive, reliable and durable strategy for managing different citrus virus and virus-like diseases under different conditions. Moreover, indexing of viruses and virus-like pathogens are very important for the production of disease free citrus nurseries. This chapter gives a brief review for the commonly used biological, serological and molecular assays for the detection of citrus virus and virus-like pathogens.
