Field Notes from Valerie Tate
Potato leafhoppers are small light green, triangular shaped insects
that feed on alfalfa during the summer. Typical damage from the
potato leafhopper includes wedge shaped yellowing of the tips of the
leaves. Damage is more prevalent in dry years. Because they are only
1/2 inch long and the move quickly, they can be difficult to see in the
field. Using a sweep net to scout is the best way to determine if
treatment is needed. We have seen potato leafhoppers reach threshold
levels at FSRC this spring. We did not treat the stand because the
alfalfa was ready to harvest, we will monitor the regrowth.
For more information about scouting and treating for potato
leafhoppers see the June 30, 2006 edition of the Integrated Pest
Management newsletter at:
