General Instructions


Bruno Herbicide is a flowable suspension concentrate herbicide which controls a range of broadleaf and grass weed seedlings as they emerge. It will also control very young weeds (up to 3 cm) that are present at time of application. It is effective through root uptake from the soil as well as foliar uptake.


Bruno has a relatively short persistence in the soil and as a consequence is unlikely to cause damage to susceptible crops following in the rotation.


Do NOT apply Bruno to soils with a high sand or gravel content e.g. sand or sandy loam soils. Bruno is not recommended for use on the Mallee soils of Victoria and South Australia. The activity of Bruno' may be reduced in soils of a very high organic matter or clay content. Bruno may be used in conventional sowing or in direct drill and retained stubble situations. For best results, weeds should be young and actively growing. The smaller the weed, the more effective the treatment. Where possible, the seed bed should be free of weeds and large clods.


Best results are obtained if irrigation is applied immediately after spraying. Under dry conditions there is no root uptake and results, especially against grass weeds and wireweed, may be poor.


Pre-planting applications of Bruno should preferably be made IMMEDIATELY prior to planting to ensure maximum residual control. Effective weed control may last from 4 to 10 weeks depending on soil temperature, soil moisture, soil microbial organisms, soil pH, soil leaching and factors affecting Bruno volatility.


Bruno is NOT recommended for control of heavy infestations of annual ryegrass and wireweed unless used in a mixture with trifluralin. Temporary crop damage (yellowing) may occur, particularly where Bruno is applied to crops grown on sand over clay (duplex) soils.




For pre-emergence applications, except in WA, weed control is generally most effective when Bruno is applied immediately after sowing and not incorporated.


Bruno should be applied uniformly by ground boom sprayer fitted with Fan Jets fully calibrated to ensure even application. Bruno should not be applied by aircraft. Spray volume is not critical but a rate of between 80 and 200 litres per hectare, at a speed of 10 to 15 kph, is suggested. If using lower spray volumes, nozzle output should not exceed 600 mL/minute. Product performance is likely to be reduced if spray equipment does not have continuous agitation during filling and constant agitation and spray pressure during the application process. When spraying, avoid overlapping of the spray bands, and shut off spray boom while starting, turning slowly or stopping. Failure to observe these procedures will cause higher rates of application on some areas resulting in crop damage. It is recommended that spraying be carried out from end to end rather than around the paddock.


Plants damaged by wheel tracking may be more susceptible to herbicide damage.




Shake or roll the container several times before measuring out product to ensure that the ingredients are well mixed. There is no need for pre-mixing. Add the product to the half filled spray tank while agitating. Continue to agitate while topping up the tank and during spraying. Reseal partly used container immediately after use.



Add the required quantity of Bruno to water in the spray tank and mix thoroughly. Maintain agitation during mixing and application



Bruno is compatible with both trifluralin and triallate. Where annual ryegrass and wireweed are present a Bruno trifluralin mixture may be used. Bruno may be mixed with triallate if wild oats are a problem weed.


Incorporation should be carried out according to the trifluralin and triallate label recommendations respectively. Where a range of depths of incorporation is indicated, these mixtures should be incorporated as shallow as possible. Heavy rain following deep incorporation (more than 5 cm deep) may result in BrunoTM being leached below the layer of germination for shallow germinating weeds (e.g. wild mustard, deadnettle). For this reason, application of Bruno.o" separately is always preferable. Where BrunoTM is incorporated alone, this should be to a depth of 2 cm only.

Where weeds have become too advanced for control prior to sowing, Bruno may be applied with a knockdown herbicide. Bruno may be used with glyphosate and a paraquat/diquat mix. When mixing glyphosate with Bruno it is necessary to add crystalline ammonium sulphate (2)/0 W/V) according to the directions on the glyphosate label.




Do NOT apply by aircraft.


Do NOT use on dry sown peas.


Do NOT use on sand or sandy loam soils as crop damage may result.


Do NOT spray when dry conditions prevail.


Do NOT apply to weeds or crops which are stressed by dry or cold weather, water-logging, disease or mechanical damage.


Do NOT apply post-emergence in conditions of very high humidity.


Do NOT apply post-emergence if rain is likely within 8 hours.


Do NOT use wetting agents with post-emergence applications.




Warning Bruno Herbicide is a member of the triazine group of herbicides. Bruno has the photosynthesis inhibition mode of action. For weed resistance management, Bruno is a Group C Herbicide. Some naturally-occurring weed biotypes resistant to Bruno and other Group C 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 Bruno or other Group C herbicides.


Since the occurrence of resistant weeds is difficult to detect prior to use, H&M NuChem Aus. Pty. Ltd. accepts no liability for any losses that may result from the failure of Bruno to control resistant weeds.


Protection of wildlife, fish, crustaceans and environment

Do NOT contaminate ponds, waterways, irrigation channels or drains with the product or used container.


Protection of crop, native and other non-target plants

Do NOT overlap spray bands as double dosage may harm the crop and other non-crop vegetation.


Do NOT allow spray drift on to susceptible crops.


Do NOT apply in high winds.


Safety Directions


Product is poisonous if absorbed by skin contact or inhaled or swallowed. Avoid contact with eyes and skin and clothing. Do NOT inhale spray mist. If product or spray on skin immediately wash area with soap and water. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water.



Store in the closed, original container, in a well-ventilated area, building or room, as cool as possible, away from children, animals or fodder. Do NOT store for prolonged periods in direct sunlight. Do NOT store with fertilisers, insecticides, fungicides and seeds. Protect product from frost.



For containers of 20 litres or less, rinse container until wash water is clear. Add rinsings to spray tank. Do NOT dispose of undiluted chemicals on-site. Break, crush or puncture and bury empty containers in a local authority landfill. If not available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, vegetation and roots. Empty containers and product should NOT be burnt.
