Reports of infestations have been made from seedlings primarily, since large plant appear to be resistant. Heavy infestations result in leaf loss and eventually plant death. Discard infested flats of seedlings as good control may be difficult with the nematicides available. Even a few infested seedlings in a flat can result in loss of the entire flat so identifying the disease early and destroying infested plants are critical to disease control. Infestations may go undetected until honeydew or sooty mold is observed.
Aphids can cause distortion of new growth or, in extreme cases, infested plants can be stunted.
Control - Aphids are relatively easy to control. However, phytotoxicity to this plant has been caused by many different chemicals. Please conduct your own tests to see what is safe under your conditions. Root aphids have been controlled with soil drenches. The adults have long bead-like antennae and their legs hang down as they fly.
