Critical comments: CROP STAGE:
Wheat, Barley, Cereal Rye, Oats and Triticale: 3 leaf to fully tillered stage (Zadok Scale Z13-30) for rates of 750 mL to 1.4 litres per hectare; 5 leaf to fully tillered stage (Z15-30) for rates of 2 litres per hectare (NSW, Vic, SA, WA, Tas only); or early tillering to fully tillered stage (Z21-30) (Qld only).
Linseed: 5 to 15 cm high.
DO NOT apply to linseed by aircraft.
# If spraying Black Bindweed when wheat, barley, cereal rye, oats, triticale or linseed is more than 30 cm high, increase spray
volume to 200 litres per hectare.
For optimal control, apply only when the weeds are actively growing. In the early stages following spraying, temporary wilting of crop and pasture may occur. Crop scorch may occur, particularly on oats, if treatment is delayed to later stages of growth.
DO NOT apply to crops or pastures undersown with lucerne, clover or medics unless some damage is acceptable.
Avoid application during temperatures above 20° C.
## Where Wireweed occurs in red soils of low fertility it has been found to be less susceptible. In these circumstances use 2 litres per hectare.

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

WITHHOLDING PERIODS:
Cereals, Pastures: DO NOT GRAZE OR CUT FOR STOCK FOOD FOR 8 WEEKS AFTER APPLICATION.
CROP HARVEST: NOT REQUIRED WHEN USED AS DIRECTED.

GENERAL INSTRUCTIONS
RESISTANT WEEDS WARNING
BRONCO MA Herbicide contains members of the Nitrite and Phenoxy groups of herbicides. BRONCO MA has the photosystem II inhibitor and plant cell growth disruptor mode of action. For weed resistance management BRONCO MA contains Group C and I herbicides.
Some naturally-occurring weed biotypes resistant to one or more of the modes of action of BRONCO MA and other Group C and I 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 may not be controlled by BRONCO MA or other Group C and I herbicides to whose mode of action they are resistant.
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 BRONCO MA to control resistant weeds. However resistance should not be assumed without first viewing the method of application, the coverage and the timing of application.

MIXING
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 again before spraying commences.

APPLICATION
BOOM SPRAYER: Calibrate the machine before use to ensure that the correct application rate is obtained. Check height of boom above the crop to ensure that the spray is evenly distributed. Wash the spray equipment thoroughly after use.
CEREALS: Apply 50-200 litres of water per hectare. A minimum of 160 litres and preferably 200 litres of water per hectare is recommended where the weed infestation is heavy or the crop cover is dense. Complete coverage of weeds is essential.
LINSEED: Apply a minimum of 220 litres of water per hectare.
TURF: Apply a minimum of 500 litres of water per hectare.
AERIAL APPLICATION: Apply a minimum of 22 litres of water per hectare. Markers should always move upwind before aircraft passes overhead. Application by micronaire equipment may give variable results.

COMPATIBILITY
This product is physically compatible in the spray tank with one of the following herbicides and insecticides in wheat and barley only: metsulfuron methyl, chlorpyrifos, dicamba, dimethoate, endosulfan, aralkoxydim, diclofop-methyl, MCPA and omethoate.
When mixed with metsulfuron methyl or dicamba, DO NOT apply to cereals undersown with lucerne.
When mixed with diclofop-methyl, DO NOT exceed 1.4 litres per hectare.
As formulations of other manufacturers’ products are beyond the control of Adama Australia Pty. Ltd. all mixtures should be tested prior to mixing commercial quantities.
