WEEDS cost Australia more than $4
billion annually in control and lost
And pest plants are estimated to cost anoth-
er $2.5b for natural environment protection.
Since European settlement, more than
28,000 exotic plants have been brought into
Australia, a few accidentally but most deliber-
Recent rains combined with slowly increas-
ing temperatures provide the perfect recipe for
a mass germination of weeds which, if not
treated now, can become a costly exercise in a
couple months down the track.
It must also be remembered that all
landowners in South Australia have a legal
responsibility to manage declared plants on
There are plenty of good reasons for jump-
ing in early to control summer weed growth,
not the least of them being that they suck valu-
able stored moisture from the soil -- vital to late
autumn pasture establishment.
Many of the newly germinating summer
weeds may be considered undesirable or nox-
ious in some regions by a number of pest con-
Landholders with grazing livestock may get
some added benefits from spraying while
plants are young in the way of extra grazing.
Some summer weeds, particularly Salvation
Jane and some thistles and broad leaf varieties
can become more palatable to some livestock
after receiving a dose of spray.
This scenario, however, should be carefully
checked out with a livestock adviser before
The starting point for summer weed control
is to walk through the paddocks as soon as a
green tinge becomes established.
After identification, the types of weeds pre-
sent and their growth stage will determine
what chemical is needed and the rate required
to control them.
The best weed kill is always achieved when
the spray is applied while they are actively
Long-term, as opposed to just summer weed
control, can also be achieved with a combina-
tion of different methods that hit weeds in dif-
ferent ways at different times.
Cultivation can kill emerging weeds, but
may through increased soil disturbance, trig-
ger the germination of others.
A well-managed grazing program may help
change the balance between some weeds and
Seed set prevention by slashing and hay
making may also help in keeping weed popu-
lations under control.
But for most it is the application of a selec-
tive herbicide that is the quickest, and some-
times the cheapest, method of control all
unwanted weed growth.
Most spray equipment manufacturers and
suppliers offer a full range of products for
broadacre, horticulture and viticulture activi-
ties along with a wide range of accessories.

USE of an innovative mobile-based
weed identification application con-
tinues to grow.
The Grains Research and
Weeds: The Ute Guide applica-
tion provides growers and farm
advisers in the southern cropping
region with a free-of-charge weeds
identification service that can be
accessed anywhere at any time via
android, iPhone or iPad devices.
The application is designed to be
used in the paddock to assist in identi-
fying the most common annual, bienni-
al and perennial weeds in southern
GRDC Regional Grower Services'
manager of delivery platforms Tom
McCue says the weed identification
tool -- a major advancement in com-
municating industry knowledge to
growers -- is the first of GRDC's popu-
lar hard copy ute guides to be convert-
ed into a mobile phone application.
He says the application, available
only in Australia and New Zealand, has
been created in a farmer-friendly for-
mat to streamline the weeds identifica-
"Where possible, photographs of the
weed at various growth stages have
been provided to ensure correct identi-
fication," Mr McCue said.
"A calendar for each weed shows
which time of the year the weed is
likely to be present in the paddock.
"And the application allows users to
search, identify, compare and email
photographs of weeds to their net-
works via their phone's inbuilt contacts
