In addition to defoliation, ARMyWoRMs and LooPeRs can invade cracks in the soil around the roots during dry years
and damage roots directly, reducing quality and/or yield.
tHResHoLD: Treat when 10 or more caterpillars (all species combined) are present per 100 row feet or per 100 sweeps with a
sweep net.

Use caution when planting into whitefringed beetle-infested fields. No soil insecticides are labeled for WHIteFRInGeD
BeetLe control in sweet potatoes. However, some soil insecticides may provide some control when applied to control other soil
insect pests.
Foliar applications against adults are aimed to minimize oviposition.
tHResHoLD: Treat when one beetle per 100 feet of bed are present or when 10 plants per 100 plants show whitefringed beetle
feeding injury. Shake plants vigorously and examine soil for dislodged beetles.
