Leaves develop chlorosis, mosaic-like patterns, and often become distorted. Water-soaked oily streaks appear on the petioles and upper part of trunks. Trees that are infected at a young stage will remain stunted and will cease to produce economical yields. Fruits may exhibit uneven coloring (color breaks) and develop ringspots.
Papaya ringspot virus (PRSV) is a viral disease transmitted by aphids. Not all aphids carry the virus, but the ones that do can infect healthy plants within minutes of landing on them.
Using insecticides to control the spread of Papaya ringspot virus is limiting since the virus is transmitted in a non-persistent manner;
Aphids may have transmitted the virus before the insecticide killed them or aphids may have landed on healthy plants for a brief moment before realizing it was drenched with insecticides. Nevertheless, that moment is all it takes for the virus to “change hands”. It is not feasible or suggested to spray against aphids every several days.
