Atraquest 900 WG Herbicide (Atrazine)

Tips For Use

General Instructions:

The maximum rate of atrazine application in all crops except plantation forestry is limited to an amount of product equivalent to 3 kg a.i. Atrazine per hectare per year.

Do not exceed this limit, especially when applying an atrazine herbicide post-emergence, where an atrazine herbicide has been applied pre-emergence.

The maximum rate of application in plantation forestry is an amount of product equivalent to 4.5 kg a.i. Atrazine per hectare per year in sandy soils and those defined as highly erodible, and a product equivalent to 8 kg a.i. Atrazine per hectare per year in clay loam and heavier textured soils.

• Application:
  • Always apply the product to an even, unridged seedbed.
• Aerial application:
  • With aerial application, the need for good soil moisture at the time of application and follow-up rain or irrigation within 10 days is most critical.
  • Apply 20 to 30 L/ha.
  • Do not use human flaggers in aerial spraying, unless protected by engineering controls such as enclosed cabs.
• Ground application:
  • Application can be made as an overall or band treatment.
  • Minimum band width should be 30 cm.
  • Apply 50 to 100 L/ha.
• TT-Canola:
  • Do not apply to TT-Canola by aircraft.
  • Apply only with a low 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 runoff is unlikely to occur or where runoff 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 the product may result in some weed growth.
• In flood or furrow irrigation situations, complete and continued activation of the product may not occur due to a thin 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.

Soil Moisture: 

• The product requires rainfall or irrigation to move it down through the soil 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.

Mixing Directions:

• Fill tank 60 – 80% full with clean water before adding Atraquest 900 WG. Begin agitating tank contents vigorously and continue agitation during the entire mixing and spraying operations.
• Pour the required amount of Atraquest 900 WG steadily into the tank. Allow vigorous bypass agitation to disperse the product completely. Do not dump product into the tank all at once.
• After adding the required quantity of Atraquest 900 WG and obtaining complete dispersion, continue to fill the tank to the desired level for spraying. Thorough agitation of the tank contents should continue during the entire spraying operation.

The Spray solution should not be left standing in the tank or spray boom lines overnight.

Restraints:

• Do not apply to waterlogged soil.
• Do not apply if heavy rains or storms that are likely to cause run-off are forecast within two days of application.
• Do not irrigate to the point of run-off for at least two 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 the product to any drainage line. Drainage lines show evidence of the action of periodically flowing water (for example, gravel, pebble, rock and sand bed, scour hole or nick point) and/or an incised channel at least 30 cm deep.
• Do not handle, mix, apply or conduct testing operations in areas susceptible to run-off where drainage results in rapid entry into waterways. These areas include roads, access tracks, snig tracks and compacted log dumps where no specific action has been taken to prevent run-off into waterways, or areas mounded perpendicular to the contour, roads, access tracks, snig tracks and compacted log dumps.
• Do not use a knapsack sprayer for application in Eucalypts and Pinus radiata plantations.

TT-Canola:

• Do not use or apply this product post-emergence on raised beds or where furrows have been created in soil for the purposes of holding or channelling water.

Crop Rotation:

• Do not plant crops other than those recommended on this label for at least 6 months following treatments at rates up to 1.4 kg/ha and for 18 months following treatments of
  1.4 to 3.3 kg/ha.

Precaution: Re-entry Period:

• Do not enter treated areas without protective clothing until the spray has dried.

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.
• Do not apply product, 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.

Protection of Wildlife, Fish, Crustaceans and Environment:

• Do not apply this product within 60 m of natural or impounded lakes or dams.
• Do not use in channels and drains.
• Do not apply under weather conditions or from spraying equipment which may cause drift of this product or spray mix onto 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.

Storage:

• Store in the closed, original container in a dry, cool, well-ventilated area out of direct sunlight.

Safety Directions:

• Avoid contact with eyes and skin. 
• Do not inhale dust or spray mist. 
• When preparing and using the prepared spray wear, use elbow-length PVC gloves.
• After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water.
