Potato Leafhopper

Posted by John Fulton -

Potato leafhopper populations have exploded in the last week. These are the small, pale green, wedge-shaped insects we often see around lights at night. The main garden crop they affect is, guess this one, potatoes. They suck sap, and inject a toxin back into the plant. The first sign is a yellow "v" at the tip of the leaf. These areas then turn brown or black. Entire plants or branches can die from these tiny insects. Control with Sevin, bifenthrin, or permethrin.
