What to look for

If you grow a crop that is a host for TPP, look for insect life stages on the underside of leaves.

Tomato potato psyllid under leaf

Tomato potato psyllid under leaf

Signs of tomato potato psyllid include:

  • Insects jumping from the foliage when disturbed.
  • Severe wilting of plants caused by high numbers of psyllids feeding.
  • Yellowing of leaf margins and upward curling of the leaves.
  • White sugar-like granules (excreted by adults and nymphs), which coats the plant leaves and stems, and can lead to the development of sooty mould.
  • Ants may be symptomatic of the presence of the white sugar-like granules.
  • Stem death symptoms are similar to other potato and tomato disorders.
