white powder on stems

Asked July 17, 2017, 7:02 AM EDT

Hi, I am finding a white powder type substance on the stems of tomatoes as well as coneflowers (not located near each other). What is this? How do I get rid of it, or can I? Can we still eat the tomatoes?

This is the protective fuzzy material produced by planthopper nymphs.No action is necessary. Here is info about them: http://extension.umd.edu/hgic/planthoppers-flowers
