Papaya ringspot virus (PRSV) is a plant pathogenic virus[1] in the genus Potyvirus and the virus family Potyviridae


In squash, watermelon and other cucurbits, PRSV strain W causes mottling and distortion of leaves and fruit. PRSV-W is considered to be one of the limiting factors in the growing of cucurbits in Florida.[2]
