Sucking Pests
Sucking pests in peanuts include leafhoppers, spider mites, three-cornered alfalfa hoppers, and thrips. Scouting for leafhoppers
and three-cornered alfalfa hoppers is best accomplished by visual observation. Gently disturb the plants and count the insects as
they fly. e use of a sweep net is difficult in peanuts because of the growth pattern. Spider mites can be detected by visually examining
the underside of leaves, and thrips are best monitored by beating young plants onto a white box or cloth to dislodge insects.

ere are several species of LeAFHoPPeRs that will feed on peanuts. e potato leafhopper is the most common. is is a
light green, wedge-shaped insect that is about one-fourth inch long. is insect feeds by sucking fluids from the leaves. Damage appears
as chlorotic spots on the tip of the leaf that become larger over time (hopper burn).
tHResHoLD: Treat when 25 percent of plants show hopper burn damage and insects are present.

Do not apply more than twice per season. Do not graze or feed livestock on treated
areas or cut treated forage for hay. Foliar burn may occur, especially if air temperature is
above 90 °F.
sPIDeR MItes are small relatives of insects that feed on the undersides of peanut leaves. Initial infestations may be in small
isolated areas of the field, then move outward. Under low infestations, leaves will become yellow. Under higher pressure, leaves
will turn brown to reddish-brown and may fall from the plant. Spider mite infestations tend to be more of a problem in hot, dry
periods.
tHResHoLD: Treat when populations threaten premature defoliation.
