LATHYRUS INSECT PROBLEMS
Aphids suck plant juices and heavy infestations may cover
the leaves with sticky honeydew.
The greenhouse leaf tier feeds on the undersides of the
leaves. The insect also rolls and ties the leaves
together.
The corn earworm feeds on the buds and foliage.
The pea moth infests the pods spoiling the seeds. Silk
and excrement can be seen when infested pods open. The
pods turn yellow and ripen prematurely. This insect is
usually not a problem unless sweet peas are grown near
garden peas.
Four-lined plant bug causes brown sunken spots on the
leaves. The insect is only occasionally found on Sweet
Pea.
