Branched broomrape has been in Australia for a number of years, and has been subject to extensive attempts to eradicate it. Last year national agreement was reached that Branched broomrape could not be eradicated. Instead, a transition program will manage the parasitic weed.
PHA is involved in the Branched Broomrape Transition to Management plan due to its growing experience with handling similar programs for Asian honey bees and Myrtle rust.
A two-year transition program aimed at managing the weed in South Australia’s Mallee region began on 1 July 2012.
Development of the Branched broomrape plan was led by representatives from South Australia and informed by extensive consultation with affected producers in the area where the weed is found, affected industries, all state and territory governments and the Australian Government.
The plan is intended to represent a collective position on the future management of Branched broomrape. The goal of the transition program is to contain the weed while industries, businesses or individuals prepare and adopt risk management measures with the aim of long-term management.
Biosecurity SA will maintain restrictions on the movement of high risk products and machinery during the two year transition, but lower risk products are able to move freely.
As part of the new program, restrictions will apply only to high risk commodities on the currently known properties infested with branched broomrape.
These properties will remain in quarantine under a Ministerial notice issued under the South Australian Plant Health Act 2009. Other properties that are currently under quarantine, but are not infested, or where broomrape has not been detected through surveys in the past 12 years, were released from quarantine on 1 July 2012.
Surveys of crops in paddocks still under quarantine will be carried out to support affected landholders with accreditation of products to provide market confidence during the 2012-13 financial year.
Research has shown that branched broomrape can be managed through on-farm biosecurity practices.
