GROUP F HERBICIDE

For control of certain weeds in clover-based pasture, field peas, lentils, lupins and oilseed poppy as specified in the DIRECTIONS FOR USE table.

GENERAL INSTRUCTIONS
For use as an early post-emergence spray in clover-based pasture, field peas, lentils, and lupins. Brodal Options may also be used as a post sowing pre-emergence spray on lupins in New South Wales, Victoria, South Australia and Tasmania.
This product provides both contact and residual activity. Residual activity can be expected for up to 8 weeks after application under favourable growing conditions. The level of effective residual control may be reduced where; rates lower than 200 mL/ha are used, dry conditions prevail, poor coverage of the soil surface is achieved, crop is planted in non-wetting sand or where soils have a high content of clay or organic matter.
Brodal Options will not effectively control; regrowth of suppressed weeds, transplanted weeds, regrowth from rhizomes or roots, or weeds growing under stress from previous herbicide applications. Weed control may be reduced in areas where trash or burnt straw from previous harvest is dense, such as in header trails. Best results will be obtained if good soil moisture exists at and after application. This product is taken up by the shoots of germinating seeds and seedlings. Susceptible weeds germinate but show immediate chlorosis followed by a mauve-pink discoloration. The chlorosis spreads with the aerial growth and the plants become necrotic and die back.
After application, some transient crop discolouration may occur. In lentils and lupins, this usually appears as yellow or white banding on the leaves, while in clover and field peas, white/pink coloration of the leaf veins and tips may occur. Some crop height reduction may also occur. Provided the crop is not under stress from pre-emergent herbicide, disease, insect damage, nutrient deficiency, frost, extremes of pH, dry or excessively moist conditions, the development of the crop and all subsequent growth will not be affected.
Some pre-emergence herbicides, such as atrazine, can cause stress to certain crops resulting in an increase in crop damage when using this product. Field peas are particularly sensitive.

Subsequent Crop Tolerance
To reduce the effect on subsequent susceptible crops (e.g. canola) ensure thorough cultivation of soil prior to the sowing of these crops.

Resistant Weeds Warning
Brodal Options is a member of the nicotinanilide group of herbicides and acts by inhibiting carotenoid biosynthesis. For weed resistance management Brodal Options is a Group F herbicide.
Some naturally occurring weed biotypes resistant to Brodal Options and other Group F 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 Brodal Options or other Group F herbicides.
Since the occurrence of resistant weeds is difficult to detect prior to use, Bayer CropScience Pty Ltd accepts no liability for any losses that may result from the failure of Brodal Options to control resistant weeds.

Mixing
Stir product or invert container several times before use as settling may occur after storage for some weeks. To ensure even mixing, half fill the spray tank with clean water and add the required amount of product. Agitate thoroughly then add the remainder of the water. Agitate thoroughly while carrying out spray operations. Reseal part-used container immediately after use.

Application
Ground
A minimum water rate of 50 L/ha should be used, however, for optimum results water rates of 70 - 100 L/ha are recommended. Increase the water volume where weed infestation is heavy or the crop cover is dense. Complete coverage of weeds is essential. Higher water volumes (up to 100 L/ha) will ensure improved activity of the product on the weeds but may increase the symptoms of crop damage.

Warning
For tank-mixtures with grass herbicides, use the recommended rates for both herbicides as well as the surfactant recommendations of the grass herbicide. Read the label for the grass herbicide before mixing and using the tank mixtures. DO NOT use crop oils with Brodal Options or Brodal Options/grass herbicide tank-mixtures. Applications to lupins and field peas under stressed conditions may cause significant damage to the crop.
When tank mixing Brodal Options and Targa, use a surfactant only. Mixtures of Brodal Options and Verdict® applied to lupins or field peas can cause damage that may result in yield losses.
Tank mixes with simazine, metribuzin or Eclipse should be applied post-emergence to lupins crops only, and only to lupin varieties and at lupin growth stages recommended for these products. Increased crop effects may be experienced with the tank mix. Do not apply Brodal Options in mixture with simazine or metribuzin to Myallie lupins if atrazine has been applied pre-emergence.
DO NOT apply tank-mixtures to clover.
As formulations of other manufacturers' products are beyond the control of Bayer CropScience, all mixtures should be tested prior to mixing commercial quantities.

DIRECTIONS FOR USE
Restraints
DO NOT apply if crop or weeds are stressed due to dry or excessively moist conditions.

CROP STAGE
CLOVER-BASED PASTURE: Apply post-emergence, not before the 3rd trifoliate leaf stage.
Warning: Some species and varieties of clover may be more sensitive than others. Refer to legume tolerance table in the general instructions. DO NOT apply to medics or yellow serradella.
FIELD PEAS: Apply early post-emergence after the third node stage and before the start of flowering.
Warning: Field peas grown on high pH soils in the presence of free lime may be less tolerant to Brodal Options.
LENTILS: Apply early post-emergence after the third leaf stage of the crop and before the start of flowering.
Warning: Some lentil varieties may be more sensitive than others. DO NOT apply to Northfield variety. Avoid spray overlap. Refer to GENERAL INSTRUCTIONS.
LUPINS: Post-emergence of Crop: Apply post-emergence from the 2 leaf stage of the crop and before the start of primary flowering (big bud).
Post-sowing, Pre-emergence of Crop (Not WA): Apply in a tank mix with the recommended rate of post-sowing pre-emergence treatment of simazine. (Brodal Options should not be incorporated).
APPLICATION AND WEED CONTROL Apply when weeds are actively growing. Good spray coverage of the weeds is important. Apply before weeds are obscured by the crop canopy. For optimum results apply 4 to 6 weeks post-sowing. Application beyond 8 weeks post-sowing may result in reduced levels of weed control. In most situations the rate specified for each weed size will give satisfactory control. Under certain conditions such as:
* high crop and weed density, * late season germinations,
* abnormal weed growth (including early flowering); higher rates of product (up to the maximum rate of application specified for that weed) may be required.

Critical comments:
CROP STAGE
Apply no earlier than the 8 leaf stage and before the start of primary flowering (big bud).
APPLICATION AND WEED CONTROL
Apply when weeds are actively growing. Good spray coverage of the weeds is important. Apply before weeds are obscured by the crop canopy. Control may be reduced where wild radish populations exceed 100 plants per m2.
Do not add crop oils, wetters, surfactants, insecticides or grass herbicides as unacceptable crop damage may occur. A minimum of ten days should elapse between application of a grass herbicide and this mixture. Do not use where water hardness exceeds 500 ppm.
Lupins should be actively growing at the time of treatment with no evidence of brown leaf spot or insect damage. A slight yellowing, often accompanied by height reduction, may be noticeable from 1-4 weeks after application, however these effects are generally transient. Avoid spraying double overlaps.

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