Then, after the disease appears, burn all infected plants and nearby ground plants and destroy all papayas within a large surrounding area. Where available, plant tolerant varieties, growing them using pesticides and anti-aphid netting for the first 3 months. After setting out, prune the young plants heavily to delay flowering and build plant strength. Use heavy and frequent anti-aphid sprays for the first year to minimize exposure. Despite these drastic measures, the local reservoir of disease will eventually increase to the point that papayas can't be grown.
Containment is impossible where papayas are grown as backyard crops, as is true in much of Asia.
Papayas, cucurbits and other host plants are commonly grown together as part of mixed gardens. Villagers certainly cannot be asked to reduce their gardens to burnt earth. The symptoms of PRV are thought by Thai villagers to mimic waterlogging and so infected plants are allowed to stand in hopes they might recover. Research institutions around the world are involved with breeding for resistance to PRV, primarily using conventional methods. Thailand, where breeding has continued for some 20 years with the support of researchers and funding from several countries, has not yet developed an esthetically acceptable papaya with lasting PRV resistance.
