Minor Pest Title

Bacterial wilt (Ralstonia solanacearum)

Minor Pest Description

This disease occurs with bad drainage, especially in the hot, wet season and is often combined with symptoms of root-knot nematodes. Plants wilt and die suddenly. When newly infected stems are cut crosswise and placed in water, a greyish or yellowish ooze appears from the cut stem. The pathogen is soil-borne with a wide host range. Root-knot nematode infestation aggravates the disease development.


Minor Pest What to do.
  • Use resistant varieties, if available.
  • Use certified disease-free seeds.
  • Remove infected plants from fields and destroy affected plants.
  • Rotate with non-solanaceous crops (e.g. maize or beans).
  • Use raised beds for improved drainage.
  • Graft plants onto resistant rootstocks.
