Gesaprim Granules Herbicide – Atrazine

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:
