Causal Agent: 

Potyvirus (Papaya ringspot virus type-W or PRSV-W)

Characteristic Symptoms:
 

Leaves of melon plants infected with the Papaya ringspot virus often develop green mosaic, malformation, puckering, blistering, distortion and narrowing of leaf laminae.
   
Fruit symptoms of infected melon plants include malformation, knobby overgrowth and color breaks.
   
Whole plant exhibit stunting when severely infected with PRSV.
   
Transmission
 
The virus is spread in a non-persistent manner by a number of aphid species, including Myzus persicae.
   

The virus is also transmitted mechanically through contaminated tools.
   
Management and Control:
 

Use of resistant varieties, if available.
   
Remove infected plants as early as symptoms are observed to minimize spread.
   
Control aphid population by spraying insecticides such as azadirachtin (neem), cartap hydrochloride (e.g. PadanⓇ, Barena 50 SP, Gemtrak®), acetamiprid (e.g. MospilanⓇ), acephate (e.g. AcetamⓇ,CompeteⓇ), chlorphenapyr (e.g. Kotetsu) or penthoate (e.g. PennantⓇ, VidexⓇ).
