ABSTRACT = {Viral diseases have been studied in-depth for reducing quality, yield, health and longevity of the fruit, to highlight
the economic losses. Positive-sense single-stranded RNA viruses are more devastating among all viruses that infect
fruit trees. One of the best examples is papaya ringspot virus (PRSV). It belongs to the genus <i>Potyvirus</i> and it is
limited to cause diseases on the family <i>Chenopodiaceae</i>, <i>Cucurbitaceae</i> and <i>Caricaceae</i>. This virus has a serious
threat to the production of papaya, which is famous for its high nutritional and pharmaceutical values. The plant
parts such as leaves, latex, seeds, fruits, bark, peel and roots may contain the biological compound that can be
isolated and used in pharmaceutical industries as a disease control. Viral disease symptoms consist of vein clearing and yellowing of young leaves. Distinctive ring spot patterns with concentric rings and spots on fruit reduce
its quality and taste. The virus has two major strains P and W. The former cause disease in papaya while the later one in papaya. Virion comprises 94.4% protein, including a 36 kDa coat protein which is a component responsible for a
non-persistent transmission through aphids, and 5.5% nucleic acid. Cross protection, development of transgenic
crops, exploring the resistant sources and induction of pathogen derived resistance have been recorded as effective
management of PRSV. Along with these practices reduced aphid population through insecticides and plant
extracts have been found ecofriendly approaches to minimize the disease incidence. Adoption of transgenic crops
is a big challenge for the success of disease resistant papaya crops. The aim of this review is to understand the
genomic nature of PRSV, detection methods and the different advanced control methods. This review article will
be helpful in developing the best management strategies for controlling PRSV.},
