Effective broad spectrum early
post-emergent aquatic weed
control in rice
DuPont now has Gulliver® + MCPA 250 registered for use in New South
Wales and Victoria.
Gulliver® + MCPA 250 is the ideal option to manage Barnyard grass and
problem broadleaf weeds such as Water Plantain, Dirty Dora, Starfruit
Spikerush and Arrowhead from the four leaf stage right through to four
stems.
The combination of Gulliver® + MCPA 250 achieves greater weed control
than either product used alone.

The key to success with Gulliver®
Gulliver® Herbicide + MCPA 250 (250 g/L sodium/potassium salt)
Gulliver® applied in a tank mix combination with MCPA (250
g/L sodium / potassium salt) as a foliar application, is a new
post-emergent herbicide treatment that offers many benefits
for weed control in NSW & Vic rice crops:
• Provides activity on both Barnyard grass and broadleaf
weeds in one treatment.
• Control of seedling Alisma & Water Plantain and suppression
of Barnyard grass.
• Control of the common broadleaf weeds Arrowhead, Dirty
Dora, Spikerush & Starfruit.
• Provides a second treatment/mode of action for Barnyard
grass populations
• The tank mix of Gulliver® + MCPA 250 provides robustness
in weed control exceeding that achieved by Gulliver® or
MCPA alone.
• Combines two modes of action (Group B & Group I).
• Has a wide application window from 4-5 leaf stage up to
3 tillered rice.
• Can be applied by ground or aerial application.
• Is very cost effective and can be used in low cost early
post-emergent resistance management programs.
• Provides greater flexibility in the timing and management
of resistance programs for aquatic weeds in rice.

some rice that has been sprayed with Gulliver® + MCPA 250.
Environmental: Avoid spraying in still conditions and winds likely to cause drifts into adjacent sensitive crops or waterways or
water bodies.
Gulliver® has been extensively field tested in the process of being registered by the APVMA. This broad testing strategy has
enabled DuPont to properly position Gulliver® as an important option for growers in the second or third pass stage of the rice
management program. An application of Gulliver® + MCPA 250 at the critical four leaf to four stems stage will help manage
weeds to maximise yield.

Application rates required for Gulliver® + MCPA 250
Rice stage
• Use Gulliver® @ 40 g/ha + MCPA 250 @ 1.6 L/ha at 4-5 Leaf Stage Rice.
• Use Gulliver® @ 40 g/ha + MCPA 250 @ 2.7 L/ha at 2-3 Stems or shoots Rice.
Specific weed target stage
• Spray Barnyard grass as early as
possible (prefer 4-5 leaf through
to first stem stage) while the weed
is actually growing in aquatic
conditions.
• Spray Water Plantain after maximum
germination has occurred (prefer
early tillering stage).
• Use the higher rate of MCPA 250
for high plant densities of broadleaf
weeds and for areas where Group
B resistant weed populations are
expected (prefer 2-3 stems or
shoots).
• For best results ensure all weeds
are 2/3 exposed. This may mean a
delayed spray with a higher rate of
MCPA.

Gulliver® + MCPA 250. The robust and effective alternative to control more
weeds to help the rice reach its full yield potential
Most post-emergent foliage application programs
will not control these weeds under the water.
By delaying spray programs for a short period to ensure
the plants are fully exposed you can use Gulliver®
+ MCPA 250 for effective weed control.
Check off these key points prior to proceeding:
Obtain and read the Gulliver® label for full product details before use and use as per label instruction.
Use an alternative mode of action grass herbicide as a pre or at sowing treatment.
Do not use on sod sown or drilled sown rice.
Apply to small actively growing weeds.
Lower water as per recommendations prior to spraying.
Expose 2/3rds of each weed above the water prior to spraying.
Weeds covered by water will not be controlled.
Weeds shaded by dense foliage will not be controlled.
Water depth at spraying should be 1-2 cm deep (Keep soil saturated at all times).
Begin refilling bays 12 - 24 hours following spraying.
Reach permanent levels within 2 days of spraying.
Subsequent weed germination’s will not be controlled and will need appropriate management strategies.
An application of Gulliver® + MCPA 250 tidied up a
paddock of rice owned by Anthony O’Connor of Deniliquin.
Mr O’Connor said the paddock was a newly bought block
that was planted on November 9 last season. “We though we
would have a Barnyard grass problem so hit it with Ordram
and then followed up with some Londax®”. High numbers of
Water Plantain and Dirty Dora in the paddock led to a followup application of Gulliver® + MCPA 250 on January 4. “It was
a tidy-up job to catch the Plantain before it seeded. As a
package Gulliver® + MCPA 250 did a good job and we didn’t
experience any burning on the crop.

Barnyard grass that had advanced to the stage where it was
one metre high and above the rice crop was controlled well
on the property of Matt Duffy of “Stanfield” Deniliquin. Mr
Duffy said the paddock had been freshly lasered with new
top-soil and was treated with Ordram and Taipan early in
the season. An application of Gulliver® on the tall Barnyard
grass controlled the weed. “It surprised me,” Mr Duffy
said. “I thought I was going to have to turn the water off.”
He said the control of the Barnyard grass was an investment
in years to come.
