Caused By:-     The Nematode Ditylenchus dipsaci

Description

The Phlox eelworm Ditylenchus dipsaci is thankfully, quite rare. It is, like most eelworms, microscopic and lives in the stems of the phlox. And overwinters in the buds at soil level. It does not enter the roots therefore root cuttings will be free from this pest. Stems appear stunted and swollen, with leaves at the shoot tips much reduced in width, sometimes little wider than the midrib. Infected shoots dieback early and do not flower. Cold weather snaps in the spring can also cause distorted foliage, but this is usually less severe and there is no abnormal thickening of the stems or early dieback.

Control

Usually the only remedy is to plant something else in the spot, but soil sterilant may enable phlox to grow again in the same spot. If it is a special Phlox root cuttings can be taken as this pest does not infect the roots.
