SITTING ON THE FENCE - Growers are urged to consider on-farm biosecurity
when using machinery after new glyphosate resistant annual ryegrass
populations were found this year.
Of the 10 new populations found, three were from fencelines in areas where
glyphosate was used extensively to control annual ryegrass, according to the
GRDC supported Glyphosate Sustainability Working Group (GSWG).
Dr Chris Preston, in charge of the GSWG ryegrass population register, said
glyphosate resistant annual ryegrass on fencelines was a particular problem
as resistance could be moved into cropped areas by farm equipment.
"Farm hygiene to prevent movement of resistance on fencelines is important
and if resistance is suspected, early action should be taken to stop
resistant weeds setting seed," Dr Preston said.

GM SEMINARS - As the genetically modified (GM) grain debate rolls on, WA
growers are encouraged to attend a round of industry and GRDC sponsored
seminars next month to hear the experiences of scientists and farmers.
The seminars, organised by GM advocate Bill Crabtree and assisted by
Producers Forum WA, will be held in Mingenew on September 4, Perth,
September 5, Wongan Hills, September 6, Bruce Rock, September 7 and
Katanning, September 8.
Mr Crabtree, of Crabtree Agricultural Consulting, said the country meetings
were for those whose livelihoods were directly affected by the prosperity of
"We will discuss concerns with the science and potential management of GMs,"
he said.
