Phylloxera aphids on Grape Vine

Asked July 19, 2016, 6:24 PM EDT

I just noticed these aphids (see photos) on the underside of my Concord grape leaves. Question: can I just cut off the leaves?

We do not recommend cutting off the leaves although a few certainly could be removed. Your grape vines do need these leaves to store energy. Here is our article on these aphids: http://www.extension.umn.edu/garden/insects/find/grape-insect-pests-of-the-home-garden/
