For control of bracken fern in pastures; grasses in sugarcane, and a range of weeds and grasses in crops and pastures as specified in the Directions for Use table.

DIRECTIONS FOR USE:
RESTRAINTS:
Do NOT apply by aircraft (except for sugarcane).
Do NOT apply if rain is expected within 3 hours (24 hours for bracken).

APPLE ORCHARS
Weeds controlled: Docks
Rate:
Boom Sprayer 4.2 L in 220 to 440 L water/ha
Knapsack or Hand Lance 1 part to 200 parts water.
State: NSW, Vic, Tas, SA, WA only
Critical comments: Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. With knapsack or hand lance, ensure uniform coverage but do not spray to run-off. Apply only to established trees. DO NOT graze the area to be sprayed for 7 days before and 21 days after application.

HOPS
Weeds controlled: Broadleaf Dock, Curled Dock, Fiddle Dock
Rate: 3.5 to 5.0 L in 220 to 440 L water/ha
State: Vic, Tas only
Critical comments: Apply before the hop plants have emerged. Apply the higher rate where Fiddle Dock is present or where docks are mainly old, established plants.

LUCERNE - established
Weeds controlled: Docks
Rate: Boom Sprayer 2.8 to 4.2 L in 220 to 440 L water/ha
State: All States
Critical comments: Lucerne should be at least one year old. Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. Apply lower rate if Curled Dock and Broadleaf Dock are present. Apply higher rate if other docks are present. DO NOT apply in spring if pasture is intended for seed production.

ONIONS
Weeds controlled: Docks
Rate: Knapsack or Hand Lance 1 part to 200 parts water.
State: Tas only
Critical comments: Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. Ensure uniform spray coverage of docks but do not spray to run-off. DO NOT apply as an overall spray as crop damage may result. Sprayed onions may show a slight yellowing but they will normally recover quickly if good growing conditions exist.

OILSEED POPPIES
Weeds controlled: Broadleaf Dock, Curled Dock
Rate: 2.5 L in 220 to 440 L water/ha
State: Tas only
Critical comments: Crop stage: Spray any time after the 4 to 6 leaf stage.
Weed stage: Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. The range of control is extended with a spray program in combination with ethofumesate as recommended by poppy contracting companies or the Department of Primary Industries, Tasmania.

PASTURES
(established & improved pastures of: Chewing’s Fescue, Cocksfoot, Perennial Ryegrass, Red Clover, Tall Fescue, White Clover)
Weeds controlled: Common Bracken
Rate:
Boom Sprayer 12.0 L plus BP Ulvapron# (2% of spray volume) in 110 to 330 L water/ha
Motorised Mister 12.0 L plus BP Ulvapron# (2% of spray volume) in 20 to 80 L water/ha
Knapsack or Hand Lance 100mL plus BP Ulvapron# (2% of spray volume) in 9.8 L water.
State: All States
Critical comments: Temporary scorch is likely to occur in perennial pastures. Apply during late April to early June after the Autumn re-growth has fully expanded, and before the first frosts of the season. Where old mature fronds exist, the bracken should be slashed or burned during October or November in the year prior to spraying. Results are first seen as a lack of spring re-growth. Ensure uniform coverage of spray over bracken. With Knapsack or hand lance, spray to give complete coverage of fronds but do not spray to run-off. DO NOT spray if rain is likely within 24 hours.

Weeds controlled: Common Bracken
Rate: Carpet Wiper 5.0 L plus BP Ulvapron# (2% of spray volume)/ha
State: Vic only
Critical comments: For East Gippsland district only. To apply the recommended rate it is necessary to select an appropriate combination of flow rate, tractor speed and herbicide dilution. Refer to General Instructions for details. This rate will control bracken growing at a density of 25 fronds per square metre. The bracken should be slashed during late Spring or early Summer in the year prior to spraying to ensure regenerated fronds of similar age. The bracken should then be wiped in the following Autumn before the first frosts of the season when the regenerated fronds are fully mature. Where fronds are of variable height or occur in dense infestation of clumps, some plants may not be contacted by the herbicide solution. In these cases, repeat treatment may be necessary.

Weeds controlled: Broadleaf Dock, Curled Dock
Rate: Boom Sprayer 2.8 L in 220 to 440 L water/ha
State: All States
Critical comments: Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. Slight yellowing of some pasture species may occur but they will normally recover quickly if good growing conditions exist. Damage to strawberry clover and subterranean clover is likely. A follow-up spray may be required to control subsequent germinations of seedlings which occur in old established stands of mature docks. Pastures should not be grazed for 2 to 3 weeks before spraying to allow sufficient growth of docks and to minimise the check to pastures. DO NOT apply in spring if pasture is intended for seed production.

PERENNIAL RYEGRASS
(for seed production)
Weeds controlled: Group A: Dock*, False Brome, Rat’s Tail Fescue, Shivery Grass, Silvery Hair Grass, Soft Brome, Squirrel Tail Fescue, Sub Clover
Group B: Madrid Brome, Prairie Grass, Sorrel, Sterile Brome, Annual poa (Winter Grass), Yorkshire Fog
Rate: 5.5 L in 160 to 220 L water/ha
State: NSW, Vic, Tas, SA only
Critical comments: Apply to established crops in the Autumn (late April-early June). The crop will show signs of yellowing 5-6 weeks after spraying. A reduction in total herbage production for 3-6 months will be experienced. Annual clovers will be affected.
DO NOT apply to cultivar Medea Ryegrass as crop yields may be affected.
DO NOT apply in spring as crop damage will result.
Group A weeds are susceptible and Group B weeds are moderately susceptible at the recommended rate.
* Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge.

POTATOES
Weeds controlled: Docks
Rate: Boom Sprayer 2.8 L in 220 to 440 L water/ha
State: Vic, Tas only
Critical comments: Apply when docks are actively growing and have fully expanded leaves, just before flowering shoots emerge. Apply before the potato foliage obscures the docks.

SUGARCANE
Weeds controlled: Awnless Barnyard Grass, Barnyard Grass, Crab Grass, Crowsfoot Grass, Green Summer Grass, Giant Paspalum, Hairy Panic Itch Grass, Johnson Grass, Para Grass, Summer Grass
Guinea Grass (Seedlings only – up to 10 cm)
Rate:
Boom Sprayer 8.5 L in 200 to 400 L water/ha
Aircraft 8.5 L in a min. 22 L water/ha
Spot Application# 200 mL in 9.8 L of water.
In mixtures with Actril* DS use at least 55 L water/ha.
State: Qld, NSW only
Critical comments: Crop stage: Apply post-emergence in plant or ratoon cane.
Weed stage: Apply when weeds are actively growing, before flowering and before they exceed 200 to 250 mm in height unless otherwise indicated. Optimal results will be obtained when the relative humidity is high (over 80%) and temperature above 17˚C. Residual control of grasses germinating from seed will persist for 6 to 10 weeks, depending on field conditions. Surfactant: Wetspray 1000 at 200 mL/100 L to improve wettability and coverage and reduce spray runoff.
Directed application: Ideally the spray should be directed to minimise coverage of the cane foliage. Aircraft application may be necessary in salvage situations and could result in some crop damage.
DO NOT apply tank mixes from aircraft.
Caution: Certain varieties have not been screened for tolerance to this product. Treat a small area first, by the same technique as that to be used commercially to check tolerance. Variety Q68 should not be treated.
# With knapsack or hand lance, ensure uniform coverage but do not spray to run-off.

NOT TO BE USED FOR ANY PURPOSE OR IN ANY MANNER CONTRARY TO THIS LABEL UNLESS AUTHORISED UNDER APPROPRIATE LEGISLATION.

WITHHOLDING PERIOD:
Apple orchards, LucernE, Onions, Pastures , Perennial ryegrass: Do NOT graze or cut for stock food for 21 days after application.

COMPATIBILITY
This product is compatible in the spray tank with Actril* DS, Wetspray 1000, BP Ulvapron*, ethofumesate and atrazine. Mixtures should not be left overnight before spraying. As formulations of other manufacturers’ products are beyond the control of Adama, all mixtures should be tested prior to mixing commercial quantities.

RESISTANT WEEDS WARNING
Rattler 400 Herbicide is a member of the carbamates group of herbicides. The product has the inhibitors of dihydropteroate synthase (DHP inhibitors) mode of action. For weed resistance management Rattler 400 is a Group R herbicide. Some naturally
occurring weed biotypes resistant to Rattler 400 and other Group R herbicides may exist through normal genetic variability in any weed population. The resistant individuals can eventually dominate the weed population if these herbicides are used repeatedly. These resistant weeds will not be controlled by Rattler 400 or other Group R herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Adama Australia pty. Ltd. accepts no liability for any losses that may result from the failure of Rattler 400 to control resistant weeds.
