These are symptoms of a virus.  It could be either papaya ringspot virus, watermelon mosaic virus, or zucchini yellow mosaic virus.  It’s difficult to distinguish the three without doing a diagnostic assay.  All three are vectored by aphids and can cause yield loss and marketability issues.  The best way to control viruses is by using resistant plant varieties when available.

 

Here is this week’s question:  What three animals left tracks on this washed out road?
