Potato leaves curling #251689

Asked June 07, 2015, 12:41 PM EDT

What is causing my potato leaves to curl up real tight after they have emerged?  They curl up and seem to be hard - not soft and pliable.  Attached are pictures taken on 6/7/15 of 3 different plants.  Thank you.

Expert Response

Thank you for your  question.

It is hard to diagnose plant diseases over the internet. When I try to zoom in the picture is too blurry. New leaves emerging on the potato plant can be caused from Potato Psyllids.

Please take a look at this link from Colorado State University.

If you are unable to detect this insect, you can take a sample of your leaves 
to the El Paso County Master Gardener Help Desk. They have a microscope 
and can take a better look. 

They are located at 17 N. Spruce St. 2nd Floor. Please call them for current 
hours of operation 520-7684.
