 In
Virginia, potato leafhopper damage usually occurs on the 2nd
through 4th cuttings. Potato leafhopper feeding can cause more
than 50% reduction in yield and up to a 25% reduction in protein
content (quality). Potato leafhopper damage can also significantly
reduce the longevity of the stand and permit increased weed growth.
During the first growing season, spring-planted alfalfa fields
are particularly attractive to potato leafhopper adults, and
the young seedlings are very susceptible to leafhopper damage. |
