Weed
invasion is one of the most serious and expensive land degradation problems
in Australia, and one of the least known and understood by the Australian
community. 'The
National Farmers' Federation estimates that the average Farmer and grazier
spends about 30 per cent of their income on pest control, a large portion of
which relates to weeds. In
these difficult times for producers it is important that we identity problem
plants before they become established and contribute further to the $3.3
billion weeds cost Australian agriculture each year" NSW Agriculture
weeds agronomist Steve Sutherland said. The
old adage: Prevention is better than cure' is certainly correct. "Where
weeds are concerned, it is always cheaper and easier to control a small
infestation or new incursion before the weed becomes established. "A
small early investment will prevent massive long-term control costs and
production losses." Weeds
can be spread in many ways. including on machinery or livestock, or as
contaminants or fodder or seed. Where
possible, buy certified seed and check the certificate to see what
weed species are present," Mr Sutherland said. Other
handy hints include:- keeping livestock in a holding paddock for 7 to 14
days; feeding stock in the same part of the paddock each time and monitoring
any plants that germinate; washing all vehicles and equipment in the same
place; and when the harvesting crops, move from the least "weedy"
to the most "weedy" paddocks. It
is not only rural landholders that should be involved. Mr Sutherland said
urban residents can assist, through identification. avoiding invasive garden
plants and correct garden waste disposal to prevent further problem weeds. |
