General Instructions


Before opening, carefully read Directions for Use, Precautionary and Protection Statements, Storage and Disposal, Safety Directions and First Aid Instructions.




DO NOT spray if weeds are wilted by dry or cold weather or if crops are at a susceptible stage, or if rain is likely in 4 hours.

DO NOT apply if frosts are imminent.

DO NOT apply to diseased or frost-affected crops or turf.




To ensure even mixing, half fill spray tank with clean water and add the required amount of this product. Agitate thoroughly, and then add the remainder of the water. Agitate again before spraying commences.




DO NOT use rain-drop or air-induction nozzles, as coverage of weeds may not be adequate.


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.

Cereals: Apply 50 to 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 or when tank-mixing with diclofop-methyl herbicide. 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 or 30 litres of water per hectare if tank mixing with diclofop-methyl herbicide. Markers should always move upwind before aircraft passes overhead. Application by Micronair equipment may give variable results.


Equipment Maintenance


After use wash application equipment thoroughly with equipment cleaner and rinse with clean water several times.




This product is physically compatible in the spray tank with one of the following herbicides and insecticides in wheat and barley only: metsulfuron-methyl, dicamba, tralkoxydim, diclofop-methyl, MCPA, dimethoate, chlorpyrifos and omethoate. When mixed with metsulfuron or dicamba, do not apply to cereals undersown with lucerne. When mixed with diclofop-methyl, do not exceed 1.4Litres per hectare. Observe all instructions on the mixture partner label. As formulations of other manufacturer’s products are beyond the control of FMC Pty Ltd, all mixtures should be tested prior to mixing commercial quantities.


Resistant Weeds Warning


FMC Bromoxynil & MCPA Herbicide is a member of both the nitrile and phenoxy groups of herbicides. FMC Bromoxynil & MCPA Herbicide has both the inhibition of photosynthesis at Photosystem II and disruption of plant cell growth modes of action. For weeds resistance management FMC Bromoxynil & MCPA Herbicide, is a Group C and Group I herbicide. Some naturally occurring weed biotypes resistant to FMC Bromoxynil & MCPA Herbicide and other Group C and Group 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 will not be controlled by this product or Group C and Group I herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, FMC Crop Protection Pty Ltd accepts no liability for any losses that may result from the failure of FMC Bromoxynil & MCPA Herbicide to control resistant weeds.


Protection of Crops, Native and Other Non-Target Plants


DO NOT apply under weather conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures. Avoid spray drift and vapour movement onto susceptible crops such as cotton, tobacco, tomatoes, vines, lupins, fruit trees and ornamentals.

DO NOT apply by misting machines.

NOTE: Maximum daily temperatures at or above 20ºC at application, or on days following treatment, may result in seedling mortality and established plants may be damaged.


Protection of Wildlife, Fish, Crustaceans and Environment


Dangerous to fish. Do not contaminate streams, rivers or waterways with the chemical or used containers.


Protection of Livestock


Grazing Precaution

Sprayed weeds may become more palatable to stock and a higher intake of some weeds may result in stock poisoning and death from causes such as nitrate poisoning. Care should be taken especially where capeweed, Paterson’s Curse and variegated thistle predominate pasture. Avoid grazing with young or breeding stock. Do not graze horses or pigs on Paterson’s curse. If in doubt, contact your nearest Department of Agriculture.


Storage and Disposal
