Economic implications of a virus prevention program in deciduous tree fruits in the US

Main viruses in sweet cherry plantations of Central-Western Spain

“…Moreover, grafting is the most common asexual method for propagating cherry trees and one of the important features for the maintaining and spreading of diseases. Among them, viral diseases are of special relevance because the trees are often asymptomatic and viruses cause significant economic loss through lower yields and reduced quality of plant products (Cembali et al, 2003). Some of the most widespread viruses affecting sweet cherry trees and other Prunus species include Prune dwarf virus (PDV), Prunus necrotic ringspot virus (PNRSV) and Apple chlorotic leafspot virus (ACLSV).…”

Determination of Major Viral and Sub Viral Pathogens Incidence in Apple Orchards in Himachal Pradesh

“…Viral and subviral pathogen free planting material is necessity both for quantity Table 1) whereas samples c and f were found infected with ASPV, ASSVd and ACLSV and quality production, because all these were well known agents for crop loss as reported from various parts of world. According to another study [1] ApMV infection alone is able to cause 46% yield reduction in Golden Delicious crop where as yield loss increase in mix infection (ApMV and Rubbery wood disease agent) results in up to 67% losses. Another study reported the effect of ACLSV, ASGV on Golden Delicious cv.…”

“…Infection effects not remain limited to yield but also responsible for 15.2-70% tree loss [21]. Study of economic implication of virus free planting material in USA indicated that the total avoidable losses due to various viruses for apple fruit and planting material industries was $63,406,789 [1]. Outcome of such study helps to emphasize the importance of awareness programs towards good orchards practices and to check viral and subviral pathogens spread from plant to plant and orchard to orchard.…”

Diversity of Apple mosaic virus Isolates in India Based on Coat Protein and Movement Protein Genes

“…The virus belongs to the genus Ilarvirus and family Bromoviridae, causes reduced shoot growth, fruit set, fruit weight, yield per tree and ascorbic acid content of the fruit [16]. More than 46% losses in Golden Delicious cultivar due to ApMV infection has been reported [5]. The virus causes line pattern symptoms in plum and is transmitted by root grafting [6] and most frequently through infected material and by mechanical inoculations onto herbaceous hosts [17].…”
