NO TO WA BRANCH OPENING: According to GRDC-supported, Albany-based DAFWA
researcher, Dr Sally Peltzer, there are many weeds that could have severe
economic impact, should they become established in Australia or spread from
existing quarantined areas within Australia.
One of these is branched broomrape, Orobanche ramosa, a parasitic weed of
pulse, oilseed and vegetable crops worldwide, as well as other broadleaf
It grows underground on the roots of a broadleaf host plant for six weeks
before emerging in late spring or early summer.
Within two weeks this small (10-30cm) plant can flower and set up to 500
thousand seeds, which are the size of dust particles and have a dormancy of
up to 10 years.
Branched broomrape was formally identified in 1992 in SA in the eastern
Murray Mallee and has been contained within the current quarantine zone of
about 190,000 hectares.
It has been the focus of a CRC for Australian Weed Management and
GRDC-funded project since 2001.
"It has never been found growing in WA, where it is a quarantine weed and a
declared plant," Dr Peltzer said.
