DELPHINIUM INSECT PROBLEMS
Aphids suck plant juices but can be controlled with
dusts or sprays.
Borers bore in stalks causing weakened, infested stalks to
wilt and fall over.
Larkspur leaf miner causes large areas of the leaf to
discolor and the leaf to collapse. Remove infested
leaves.
Slugs feed on the leaves, flowers and stems at night.
Slugs leave a trail of slime which looks as though varnish
was dribbled on the plant.
Cyclamen mites cause much distortion of the growing tips.
