Resumen

Branched broomrape is a parasitic weed of a wide range of broadleaf crops internationally. Broomrapes are root parasites that extract all of their nutritional requirements from their host plants, which if not managed can reduce yields. There have been no yield problems observed in Australia where in-crop herbicide application is utilised. It has a long-lived seed bank, which can survive for at least 12 years

Peligro
A small outbreak of branched broomrape has been under eradication in South Australia since 1992. A recent review determined that eradication was no longer technically feasible. An official program has been established to contain the infestation under official control provisions of the IPPC for two years to allow industries and individuals to develop and implement farm biosecurity plans. The South Australian Government will continue to maintain restrictions on high risk pathways from known infested properties through noxious weed declaration under the Natural Resources Management Act 2004. Products that pose a lower risk of spreading the pest will be able to move freely. Research has shown that branched broomrape can be readily managed through on-farm biosecurity practices.
