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.
