If you have a papaya plant like the one in photo, there is no way to save it. Pull it out and burn or bury it deeply. It is infected by PRSV or Papaya Ring Spot Virus.
To avoid the occurrence of the disease in your farm, plant a variety that is resistant to PRSV. Relatively resistant is the Sinta papaya. The disease can be spread by aphids so make sure to control the aphids by spraying plants in the farm with insecticide that will eliminate the aphids.
Experts also recommend crop rotation with non-host plants. That means that after the papaya crop is over, plant another crop that is not affected by the virus.
