Broomrape in Tomato

Orobanche minor
  • Use clean seed to reduce the chance of contamination
  • Seeds are transported by water - Prevent water runoff from infested land to prevent seed introduction
  • Seeds are spread by animals - do not allow livestock into an affected area to avoid spread
  • Seeds travel on machinery - clean equipment and vehicles after work in infested areas
  • Crop rotation with non-hosts such as linseed, onion, cucumber or carrots, may help to deplete seed bank
  • Avoid seed set, as the seeds are very long-lived
  • Before planting, cover the soil with transparent plastic for four weeks to kill the weed seeds and germinating young seedlings
  • Annual, herbaceaeous, succulent, parasitic plants that lack chlorophyll. 30-50cm tall but can exceed 100cm (especially in Ethiopia). Stems are un-branched, yellowish-brown, often tinged with purple. A root parasite seen only on host roots.
  • Look for stunted crop growth and chlorosis
  • Light infestations can usually be controlled by hand pulling or hoeing before seed is produced. Then bury them deep, at least 60 cm if possible
  • Wash hands after handling the plants to prevent spread of seed
  • Use of chemical herbicides may lead to the development of herbicide resistance.
  • When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
  • Use glyphosphate when infestation is severe in order to prevent the estabshment of seed bank. This will kill the weed and the crop. Use 2L/ha.
  • Glyphosate is WHO Class III (slightly hazardous)
