Gesaprim Granules Herbicide acts mainly through root absorption, its effectiveness depends on the occurrence of control rainfall or irrigation to move it down into the weed zone. Duration and effectiveness of control depend on the amount of chemical applied, soil type, rainfall and particular weed species.

The application of Gesaprim Granules Herbicide is by incorporation into the soil (pre-plant and at sowing applications).  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. A Delay in the 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. Always apply the product to an even unridged seedbed.

The active ingredient in Gesaprim Granules Herbicide, Atrazine, is a herbicide of the triazine class and is used to stop pre and post-emergence broadleaf and grassy weeds in crops such as sorghum, maize, sugarcane, lupins, pine, and eucalypt plantations, and triazine-tolerant canola.  Atrazine continues to be one of the most widely used herbicides in Australian agriculture.

Tips For Use

Restraints:

  • Do not use it as a pre-emergence spray on light sandy soils.
  • Do not use on weeds over 4 cm tall.
  • Do not apply to waterlogged soil.
  • Do not apply if heavy rains or storms that are likely to cause runoff are forecast within 2 days of application.
  • Do not irrigate to the point of runoff for at least 2 days after application.
  • Do not use a pre-emergence application in sorghum, broom millet or saccaline during the wet season in the northern irrigation areas of WA.
  • 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.
  • Do not apply product to any drainage line. Drainage lines show evidence of the action of periodically flowing water (eg gravel, pebble, rock or 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 a 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.

Soil moisture:

  • Gesaprim Granules 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.

General Instructions:

  • Gesaprim Granules is a pre-emergence and post-emergence herbicide that controls weeds from seed and weed seedlings. However, established perennial species, large annuals, and large broadleaf weeds are not satisfactorily controlled at the rates recommended.
  • It acts mainly through root absorption, its effectiveness depends on the occurrence of control rainfall or irrigation to move it down into the weed zone. Duration and effectiveness of control depend on the amount of chemical applied, soil type, rainfall and particular weed species.
  • The maximum rate of atrazine application in all crops except plantation forestry is limited to an amount of product equivalent to 3 kg ai atrazine/ha 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 ai atrazine/ha per year in sandy soils and those defined as highly erodible, and product equivalent to 8 kg ai atrazine/ha per year in clay loam and heavier textured soils.

Precautions:

  • Re-entry period – Do not enter treated areas without protective clothing until spray has dried.

Storage:

  • Store in the closed, original container in a cool, well ventilated locked area. 
  • Do not store for prolonged periods in direct sunlight.

Safety Directions:

  • Avoid contact with eyes and skin. 
  • Do not inhale dust or spray mist. 
  • When preparing spray and using the prepared spray, wear:
    • cotton overalls buttoned to the neck and wrist (or equivalent clothing),
    • a washable hat, and
    • elbow-length PVC gloves.
  • If using a hand directed sprayer, wear in addition: waterproof trousers and boots.
  • After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day’s use, wash gloves.

First Aid:

  • If poisoning occurs contact a doctor or Poisons Information Centre. Phone Australia 131 126.
  • For further information, refer to the Safety Data Sheet (SDS).
