Overview A pre-emergent and post-emergent herbicide for the control of annual grasses and broadleaf weeds in a range of crops and Pinus radiata plantations and for use in triazine tolerant canola.
Chemical Group triazine
General Instructions DO NOT APPLY MORE THAN 6 LITRES PRODUCT/HA/YEAR EXCEPT IN FORESTRY SITUATIONS
This product can be used both pre- and post-emergent to selectively control weeds in the crops listed in the Directions for Use Table and in Pinus radiata plantations. It can also be used to control weeds in Triazine Tolerant Canola varieties. Established perennial species will not be controlled at the rates recommended. Duration and effectiveness of control depends on the amount of chemical applied, soil type, rainfall, weed species and other conditions. Sufficient moisture (either rainfall or irrigation) is required to move the product into the root zone of weeds to make the product effective. This should occur within 10 days of application to ensure product effectiveness.
DO NOT apply more than 6 litres per hectare per year for all crops except forestry.
DO NOT apply more than 9 litres per hectare per year in forestry situations in sandy soils and soils classed as highly erodible and not more than 16 litres per hectare per year for clay loams and heavier textured soils.

Integrated Weed Management Strategy for TT Canola
The use of this product in TT Canola is subject to an Integrated Weed Management Strategy for the use of triazine herbicides in TT Canola.
The strategy encompasses:
- Integrated Weed Management;
- the specific management of crop plant volunteers and outcrossing to other plants; and
- triazine herbicide residue management (agronomic and environment).
Compliance with registered label directions and adoption of the principles outlined in the Strategy will assist with implementation of crop management practices that minimise the development of herbicide resistance in treated weeds, reduce the levels of triazine residues in the environment, and manage volunteer plants and outcrossing. Copies of the Strategy are available from your Sipcam representative or by contacting Sipcam Australia Pty Ltd Pty Ltd, Level 1, 1 Malop Street Geelong, Vic 3220.
Where specific information and farm management assessment is required to assist with application of Integrated Weed Management programs on-farm, particularly in adapting strategies to local conditions, then specific expert advice should be obtained from an appropriate agronomist, consultant, chemical supplier or Departmental adviser.
To minimise herbicide resistance:
Avoid dry sowing in heavily weed infested paddocks. Wait for a weed germination after the opening rains in weedy paddocks. Use a pre-plant knockdown or cultivation. No weeds should be allowed to survive at this stage. Adapt the weed control program to the anticipated weed spectrum and pressure
Broadleaf Weeds and Ryegrass: Use Simazine 500 g/L Herbicide or Sipcam Atrazine 500 SC Herbicide plus trifluralin pre-emergence. A follow-up with a Group A herbicide (if Ryegrass is susceptible) or Sipcam Atrazine 500 SC Herbicide may be necessary.
Broadleaf Weeds only: Use Sipcam Atrazine 500 SC Herbicide post-emergence.
- DO NOT use Simazine 500 g/L Herbicide or Sipcam Atrazine 500 SC Herbicide if the area to be treated had a triazine herbicide applied to it last season.
- Watch for escapes, especially in paddocks with a long history of Group C herbicide use.
- DO NOT use Group C herbicides in consecutive years.

Resistant Weeds Reporting
Growers should collect plant or seed samples where weeds that are normally susceptible to atrazine and simazine may be resistant, get them tested and seek professional advice.
To avoid Triazine carry-over:
On acid soils (pH less than 6.5) - The maximum rate of use Simazine 500 g/L Herbicide or Sipcam Atrazine 500 SC Herbicide or a combination of the two products to be applied to the crop during the growing season is 4 L/ha.
On alkaline soils (pH greater than 6.5) - The maximum rate of Simazine 500 g/L Herbicide or Sipcam Atrazine 500 SC Herbicide or a combination of the two products applied to be applied to the crop during the growing season is 2 L/ha.
Post-emergence use - It is recommended that Sipcam Atrazine 500 SC Herbicide only be used, and at rates of 2 L/ha or less, on both acid or alkaline soils.

Warning
Sorghum, Broom Millet, Saccaline
Heavy rain immediately after application may result in excessive concentrations of herbicide in the seed furrow, encouraging crop injury. This is most likely to occur in pre-plant or pre-emergence applications using rates in excess of 3.6 L/ha. To avoid the likelihood of herbicide injury use technique (a), (b) or (d) in the Time of Application table. DO NOT use as a pre-emergence application in the wet season in the northern irrigation areas of Western Australia. When sowing is made on the flat avoid application to ridged soil. Applying the total amount of product as a pre- emergence application will increase the risk of crop injury in the event of heavy rain after application.
Maize, Sweet Corn
For post-emergence application add crop oil at the rate of 5.5 L/ha if grass weeds are a problem. Ensure that the mixture is continually agitated. DO NOT apply mixtures of crop oil to stressed crops, inbred lines or breeding stock as injury may occur. If only broadleaf weeds are a problem, add 135 mL of a 100% non-ionic surfactant per 100 L of spray mixture.

Mixing
DO NOT mix, load or apply this product within 20 m of any well, sink hole, intermittent or perennial stream. Stir the product or invert the container prior to use in case settling has occurred in storage. Partially fill the spray tank with water and maintain agitation while adding the required quantity of Sipcam Atrazine 500 SC Herbicide. Agitation should continue after filling and during spraying. If spray is allowed to stand, agitate thoroughly before resuming spraying.

Compatibility
This product is compatible with Glyphosate 360 and Glyphosate 450, paraquat, paraquat/diquat mixtures and amitrole. It is advisable that a small scale compatibility test be carried out prior to tank mixing with other products. In sugar cane only, the addition of Sodium 2,4-D will assist in short term suppression of Nutgrass and other sedges.

Application
Application can be made by low volume boom or by aircraft (except in TT Canola). Suggested minimum volumes of spray mixture per hectare are:
Boom: Pre-Plant/Pre-emergence - 55L ; Post emergence - 110L
Air: Pre-Plant/Pre-emergence - 15L ; Post emergence - 22L
Application can be made as an overall spray or as a band spray. Minimum band width should be 30 cm. DO NOT use human flaggers in aerial spraying, unless protected by engineering controls such as enclosed cabs.
TT Canola - DO NOT apply TT Canola by aircraft. Apply only with a low volume boom sprayer with a 60 m buffer zone downwind of treated fields to natural or impounded lakes or dams, and a 20 m buffer zone for any well, sink hole, intermittent or perennial stream. Apply only to areas where run-off is unlikely to occur or where run-off may be captured by farm earthworks.
Incorporation (Pre-plant and at sowing application)
This product acts mainly by root absorption. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the weed root zone. Sufficient rain or irrigation to thoroughly wet the soil through the weed root zone should occur or be made immediately after application to provide appropriate weed control. Delay in activation of this product may result in some weed growth. In flood or furrow irrigation situations complete and continued activation of the product due to a thin hard band of dry soil on the surface during or after irrigation. Mechanical incorporation after application, using light harrows to incorporate the product into the soil not more than 4 cm deep is required to ensure the irrigation water activates the product. Always apply the product to an even unridged seedbed.
Time of Application
For dryland and irrigated Sorghum, Broom Millet, Saccaline, Maize and Sweet Corn.

Restraints DO NOT apply to waterlogged soil.
DO NOT apply if heavy rains or storms that are likely to cause surface runoff are forecast within two days of application.
DO NOT irrigate to the point of runoff for at least 2 days after application.
DO NOT use as a pre-emergence application in sorghum, broom millet, or saccaline during the wet season in the Northern Irrigation areas of Western Australia.
DO NOT apply product to any drainage line. Drainage lines show evidence of the action of periodically flowing water (for example, gravel, pebble, rock or sand bed scour hole or nick point) and/or an incised channel at least 30cm deep. DO NOT handle, mix, apply or conduct testing operations in areas susceptible to runoff where drainage results in rapid entry into waterways, particularly where no specific and effective action has been taken to prevent runoff into waterways. These areas may include areas mounded perpendicular to the contour, roads, access tracks, snig tracks, and compacted log dumps.
TT canola: DO NOT use or apply this product post-emergence on raised beds or where furrows have been created in the soil for the purpose or holding or channelling water.
SOIL MOISTURE: This product requires rainfall or irrigation to move it down into the weed root zone to make it effective. Sufficient rain or irrigation to thoroughly wet the soil through the weed root zone should occur or be made within 10 days after spraying.
Resistance Warning Sipcam Atrazine 500 SC Herbicide is a member of the triazines group of herbicides. Sipcam Atrazine 500 SC Herbicide has the inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management Sipcam Atrazine 500 SC Herbicide is a Group C Herbicide. Some naturally occurring weed biotypes resistant to Sipcam Atrazine 500 SC Herbicide 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 Sipcam Atrazine 500 SC Herbicide or any other Group C herbicide. Since the occurrence of resistant weeds is difficult to detect prior to use, Sipcam Pacific Australia Pty Limited accepts no liability for any losses that may result from the failure of Sipcam Atrazine 500 SC Herbicide to control resistant weeds. Any incidents of resistance must be reported to Sipcam Pacific Australia Pty Ltd.
Protection of wildlife, fish, crustaceans and environment DO NOT mix/load or apply product within 20m of any well, sink holes, intermittent or perennial streams or river. DO NOT apply this product within 60m of natural or impounded lakes or dams. DO NOT use in channels or drains. DO NOT apply under meteorological conditions or from equipment which could be expected to cause drift of this product or spray mix into adjacent areas, particularly wetlands, waterbodies or watercourses. DO NOT contaminate streams, rivers or waterways with the chemical or used containers. This product is very highly toxic to algae and aquatic macrophytes.
Protection of crop, native and other non-target plants Do not spray foliage of desirable plants. Do not apply high rates of application to heavier soils if roots of desirable shrubs and trees are near the surface. Do not use in channels or drains. Do not use near newly planted shrubs, young ornamentals or species with shallow roots eg Prunus species or trees in sandy porous soils. Do not apply under weather conditions or from spraying equipment that may cause spray to drift onto nearby susceptible plants/crops, cropping land or pastures. Do not apply or drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend or in locations where the chemical may be washed or moved into contact with their roots. Do not plant crops other than those recommended on this label for at least 6 months following treatments at rates up to 2.5L per hectare and for 18 months following treatments of 2.5L to 6.0L per hectare. Do not apply in excess of 5.9L product/ha in any one year, except in forestry situations.
