Herbicide to control broadleaf weeds before sowing of cereals and pastures

What is 2,4-D Amine 625 used for?

2,4‑D Amine 625 is a selective Group I herbicide used for controlling broadleaf weeds in fallow paddocks, before direct drilling or sowing of cereals and pastures, and in established cereal crops, pastures, sugar cane, peanuts and certain non‑agricultural areas when used as directed. It contains 625 g/L 2,4‑D present as the dimethylamine and diethanolamine salts.

2,4‑D Amine 625 controls a wide range of broadleaf weeds, including common problem species such as capeweed, wild radish, wild turnip, various thistles, Paterson’s curse, dock, doublegee, cape tulip and other weeds listed in the Directions for Use. The exact weeds controlled, and the best rate and timing, depend on the crop or pasture, the state, and the growth stage of both crop and weeds, so you must follow the weed tables on the Application Guide and Directions for Use for your specific situation.

2,4‑D Amine 625 can be used:

  • In fallow and stubble situations before sowing.
  • Before direct drilling or sowing of winter cereals and pastures.
  • In cereal crops such as wheat, barley, oats, cereal rye, triticale and millet.
  • In pastures, including spray‑graze programmes.
  • In sugar cane and peanuts, under specific timing and rate restrictions.
  • In certain non‑agricultural situations such as rights‑of‑way and industrial areas, as per the Directions for Use.

Always check that your intended crop, situation and state are covered in the current Directions for Use before applying.

Yes. 2,4‑D Amine 625 can be used in fallows, stubble sprays and conservation tillage situations before sowing or direct drilling of cereals, grain legumes, canola and pastures where these uses are listed. You must observe the specified plant‑back periods and any additional restrictions for particular crops, states or dryland pre‑emergent uses.

In some pre‑sowing and fallow situations, 2,4‑D Amine 625 may be tank‑mixed with other herbicides such as chlorsulfuron or paraquat‑based products (for example Sprayquat) as examples only where grasses are present and such mixtures are allowed. It may also be used in combination with other herbicides (for example certain dicamba or diuron products) where this is supported by the Directions for Use and the partner label.

Always check both product directions for the specific crop, rate, timing and tank‑mix compatibility before mixing and applying.

2,4‑D Amine 625 is a phenoxy herbicide and can cause severe damage to native vegetation and susceptible crops such as cotton, grapes, tomatoes, oilseed crops and ornamentals if spray drifts off target. Do not apply in a manner that may cause off‑target drift, do not spray unless wind speed at the application site is between 3 and 20 km/h, and do not apply under hazardous surface temperature inversion conditions. You must also observe any specified buffer distances and equipment requirements for boom spraying or aerial application given in the Directions for Use.

When opening containers, preparing spray or handling undiluted concentrate, you must wear chemical‑resistant waterproof clothing over normal clothing, a washable hat, elbow‑length chemical‑resistant gloves, impervious footwear and a full face‑piece respirator with an organic vapour/gas cartridge or canister.

For application:

  • With enclosed‑cab boom spray equipment with air filtration, or for aerial application, wear cotton overalls buttoned to the neck and wrist (or equivalent clothing) and elbow‑length chemical‑resistant gloves.
  • With open‑cab boom spray equipment or hand‑held equipment, wear chemical‑resistant waterproof clothing over normal clothing, a washable hat, elbow‑length chemical‑resistant gloves and a full face‑piece respirator.

After use, wash exposed skin and contaminated clothing as directed in the safety directions.

For pasture and cereal crops, stock must not graze or be fed cut fodder from treated areas for 7 days after application. In fallow situations, treated areas should not be grazed, cut or cultivated for at least 21 days after spraying. For sugar cane, workers must not hand‑harvest for at least 1 day after application, and if early re‑entry is required before spray deposits have dried, suitable clothing and water‑resistant footwear should be worn as specified.

Store the product in the closed, original container in a cool, well‑ventilated area, and do not store it for prolonged periods in direct sunlight. Triple‑rinse containers before disposal, adding rinsings to the spray tank, and do not dispose of undiluted chemical on site. Clean containers with the drumMUSTER logo that are dry and free of residues may be recycled through an approved programme; otherwise dispose of empty containers at an approved waste management facility, or in a disposal pit set up in accordance with local regulations where this is permitted.

2,4-D Amine 625 is used in peanuts to control broadleaf weeds and certain grass weeds in band-sprayed and overall pre-emergent programmes in approved regions. Uses are subject to specific timing restrictions and usage conditions, so always consult Appendix 1 and the Directions for Use before applying in peanuts.

In peanuts, this product controls broadleaf weeds (except Noogoora burr) and grass weeds (except Mossman burr) when used at the correct rate and timing. The choice between band spraying and overall spraying, and the rate within the range, depends on whether the crop has emerged, the weed spectrum, soil and seasonal conditions, and the timing rules for your region.

Situation / Crop Target Weeds State / Region Rate / Ha Critical Comments
Peanuts – band spray after planting Broadleaf weeds (except Noogoora burr) QLD & NT (as per Directions for Use) 1.8L – 3.6L / Ha (band equivalent) Lower rate: apply as a band spray as soon as possible after planting in a 55cm band over the seed row. Ensure accurate band width and nozzle setup so the band rate matches the intended per-hectare dose. Usage restrictions and timing rules apply – see Appendix 1 for regional timing for dryland and irrigated peanuts.
Peanuts – overall pre-emergent spray Grasses (except Mossman burr) and broadleaf weeds listed for this use QLD & NT (as per Directions for Use) Within 1.8L – 3.6L / Ha range as directed Higher rate: apply as an overall spray after planting and before crop emergence. Some crop damage may occur if heavy rain falls between application and crop emergence. Follow Appendix 1 timing restrictions for specific regions (for example Cape York, Northern Gulf and Northern Territory) and ensure the soil surface is even and free from large clods at application.

Important notes:

  • Usage restrictions and timing rules apply in peanuts; always consult Appendix 1 before spraying.
  • Do not apply to peanuts outside the listed regions or time windows in the Directions for Use.
  • Monitor crops closely where heavy rain occurs between application and emergence, as some crop damage may occur.
  • Always use this Application Guide together with the full Directions for Use and Appendix 1 to confirm the correct rate, spray volume, band width, timing and any regional limitations.

2,4-D Amine 625 can be used as a harvest aid or salvage spray in winter cereals to help desiccate broadleaf weeds prior to harvest in approved situations. This use is restricted to specific growth stages and rates, and is not a substitute for normal in-crop weed control.

The harvest aid application targets surviving broadleaf weeds late in the season to assist with harvesting and reduce contamination from problem species. Timing is critical – sprays must only be applied once the crop has reached the dough stage, and all withholding periods and harvest intervals must be observed.

Situation / Crop Target Weeds State Rate / Ha Critical Comments
Harvest aid / salvage spray – winter cereals Desiccation of broadleaf weeds in winter cereals All States (where listed) 1.2L – 1.7L Apply after the crop reaches the dough stage, as a harvest aid or salvage spray to desiccate surviving broadleaf weeds. Do not apply earlier than the specified growth stage. Observe all withholding periods and any specific harvest or grazing intervals given in the Directions for Use before cutting or grazing treated crops.

Important notes:

  • Use only as a salvage or harvest-aid treatment in winter cereals, not as a routine in-crop spray.
  • Apply strictly after the dough stage as specified; earlier applications may damage yield or quality.
  • Observe all label restraints, spray drift requirements and withholding periods before harvest or grazing.
  • Always use this Application Guide together with the full Directions for Use to confirm the correct rate, timing, and any harvest or grazing intervals for your situation.

2,4-D Amine 625 is used in established pastures to control a range of broadleaf weeds and thistles, including through spray-graze programmes in southern states. These uses rely on both correct spraying and follow-up grazing pressure, and are subject to specific usage restrictions and timing rules, so always consult Appendix 2 and the Directions for Use before applying to pastures.

In pastures, target weeds include Amsinckia, capeweed, doublegee, mustards, Paterson's curse, wild turnip, wild radish, docks, geranium, erodium and a range of annual and spear thistles, as listed in the Directions for Use. Effective control depends on weed growth stage, correct rate selection, and maintaining the recommended high stocking rates after spraying.

Situation / Crop Target Weeds State Rate / Ha Critical Comments
Pastures – spray-graze programme (SA) Amsinckia, thistles, capeweed, doublegee, mustards, Paterson's curse, wild turnip, wild radish, docks, geranium, erodium SA only 560mL / Ha Apply from 6 weeks after the opening autumn rains and continue until the end of August. Seven days after spraying, stock the paddock at 4–5 times the normal rate, preferably with sheep, and maintain this level of grazing for around 6 weeks or until the pasture shows signs of overgrazing. Then return to normal stocking levels. See Appendix 2 for full spray-graze timing guidance.
Pastures – spray-graze (VIC & TAS) Annual thistles, capeweed, doublegee, mustards, Paterson's curse, turnip, saffron thistle, spear thistle, geranium, slender thistle VIC & TAS only Within label rate range (refer to Table 3) Apply to actively growing weeds at the recommended growth stage as per Table 3, then implement high stocking rates in the following spring to prevent weeds from flowering. Repeat spray-graze treatments may be required for 2–3 years to achieve complete control. See Appendix 2 for application and timing restrictions for pastures.
Pastures – spray-graze (WA) Amsinckia, seedling docks, capeweed, doublegee, mustard, wild radish, wild turnip, Paterson's curse, annual thistles, spear thistle, saffron thistle WA only 600mL – 800mL / Ha (up to 1.2L for some thistles) Apply to actively growing weeds at the stages specified in Table 3. For saffron thistle, apply at about 1.2L/Ha at the end of September when plants are running up to flower. Sub‑clovers may be damaged at this rate and use is not recommended for all medic pastures. Heavy stocking on young melons sprayed with 1.6L/Ha plus 800mL/Ha and 1% oil provides effective control. Follow all usage restrictions and spray-graze notes in Appendix 2.

Important notes for pastures and spray-graze:

  • Spray-graze programmes can increase the amount of poisonous plants eaten by stock (for example Caltrop, capeweed, Paterson's curse, variegated thistle), and deaths can result from causes such as nitrate poisoning; use care when planning grazing.
  • With Paterson's curse, preferably graze stock soon destined for slaughter and avoid extended grazing; avoid grazing with young or breeding stock and do not graze horses or pigs on Paterson's curse.
  • Always follow Appendix 2 for application and timing restrictions for pastures, including recommended stocking rates and duration.
  • Always use this Application Guide together with the full Directions for Use and Appendix 2 to confirm the correct rate, spray volume, timing, grazing strategy and any regional limitations.

2,4-D Amine 625 is used in non-crop situations such as agricultural non-crop areas, commercial and industrial sites, roadsides, rights-of-way and other non-agricultural areas to control a range of broadleaf weeds. These uses help manage problem weeds in fence lines, around buildings, in transport corridors and in other areas where crop selectivity is not required.

Target weeds in non-crop areas include thistles, capeweed, Paterson's curse, wild radish, wild turnip, docks and other broadleaf species listed in the Directions for Use, as well as Pimelea spp. in specific districts. Rates and timing vary with the weed species, growth stage and the sensitivity of nearby crops, pastures and native vegetation, so always follow the Directions for Use carefully.

Situation / Use Area Target Weeds State / Region Rate / Ha Critical Comments
Agricultural non-crop areas, commercial and industrial areas, roadsides and rights-of-way Broadleaf weeds including thistles, capeweed, Paterson's curse, wild radish, wild turnip, docks and other species listed for non-agricultural areas All States where use is permitted Within label rate range (refer to Table 3 and weed table) Apply to actively growing weeds, selecting the rate according to weed species, size and density. Use calibrated ground equipment and avoid drift onto sensitive crops, pastures and native vegetation. Observe all spray drift restraints, buffer zones and no-spray areas specified for non-agricultural uses.
Non-agricultural areas – Pimelea spp. Pimelea species (as listed in the Directions for Use) Relevant districts only (refer to label) Up to 800mL / Ha (as directed) Apply to actively growing Pimelea plants at the growth stages specified for your district. Consult local advice where Pimelea is a serious problem and follow any specific regional guidance on timing and pasture management after spraying. Avoid grazing stock on treated areas until Pimelea plants have sufficiently broken down, as per the Directions for Use.

Important notes for non-crop and non-agricultural areas:

  • Always observe spray drift restraints, buffer zones and no-spray areas when treating roadsides, rights-of-way and other public places, and comply with any local government or authority requirements for weed control in public areas.
  • Take particular care near sensitive crops, pastures, waterways and native vegetation, as 2,4-D can cause severe damage to susceptible species such as cotton, grapes, tomatoes, oilseeds and ornamentals.
  • When treating Pimelea or other poisonous plants, follow all grazing and re-entry directions in the label to protect livestock.
  • Always use this Application Guide together with the full Directions for Use (including Table 3 and the weed table) to confirm the correct rate, spray volume, timing and any regional or access restrictions.
