DIRECTIONS FOR USE
Restraints

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 as a pre-emergence application in broom millet, saccaline or sorghum 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 channeling 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 runoff 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 runoff into waterways, or areas mounded perpendicular to the contour, roads, access tracks, snig tracks and compacted log dumps.
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.

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. 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.

Resistant Weeds Warning
GESAPRIM GRANULES 900 WG Herbicide is a member of the triazine group of herbicides and has the inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management this product is a Group C herbicide. Some naturally occurring weed biotypes resistant to GESAPRIM GRANULES 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 GESAPRIM GRANULES or other Group C herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Syngenta Australia Pty Ltd accepts no liability for any losses that may result from the failure of GESAPRIM GRANULES to control the resistant weeds.
Advice as to strategies and alternative treatments that can be used should be obtained from your local supplier, consultant, local Department of Agriculture, Primary Industries Department or a Syngenta representative.
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. Any incidents of resistance must be reported to Syngenta, phone 1800 067 108.
To minimise herbicide resistance
- Avoid dry sowing in heavily weed infested paddocks. Wait for 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 Gesatop or GESAPRIM plus trifluralin pre-emergence. A follow-up with a Group A herbicide (if Ryegrass is susceptible) or GESAPRIM may be necessary.
Broadleaf weeds only: Use GESAPRIM post-emergence.
- DO NOT use GESAPRIM or Gesatop 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.
To avoid triazine carry-over
On acid soils (pH less than 6.5): The maximum rate of GESAPRIM or Gesatop or a combination of the 2 products to be applied to the crop during the growing season is 2.2 kg/ha.
On alkaline soils (pH greater than 6.5): The maximum rate of GESAPRIM or Gesatop or a combination of the 2 products to be applied to the crop during the growing season is 1.1 kg/ha.
Post-emergence: It is recommended that GESAPRIM only be used, and at rates of 1.1 kg/ha or less, on both acid or alkaline soils.

Integrated Weed Management Strategy for TT-Canola
An Integrated Weed Management Strategy for TT-Canola (the Strategy) has been developed by Syngenta with the assistance and agreement of the Canola Association of Australia. The Strategy outlines recommendations, measures and options for weed management, including management of herbicide resistance in weed populations. The Strategy is available from a Syngenta representative and the Canola Association of Australia. A program has been developed that outlines sound agronomic practices and integrated weed management programs designed to optimise the performance of TT-Canola. It is advised that consultation on IWM be undertaken with an accredited agronomist prior to use of GESAPRIM GRANULES on TT-Canola.

Important: Use may not control canola escapes or weedy canola relatives if triazine tolerant. Syngenta, the Canola Association of Australia, neighbouring land managers and growers should be notified of suspected incidents of resistance.

DO NOT mix, load or apply this product within 20 m of any well, sink hole, intermittent or perennial stream.

Mixing
This product must be mixed with water and applied by suitable spray equipment.
- Fill vat no more than 25% full with clean water before adding GESAPRIM GRANULES. Begin agitating vat contents vigorously and continue agitation during entire mixing and spraying operations.
- Pour required amount of GESAPRIM GRANULES steadily into vat. Allow vigorous bypass agitation to completely disperse product. DO NOT dump product into vat all at once.
- After adding required quantity of GESAPRIM GRANULES and obtaining complete dispersion, continue to fill vat to desired level for spraying. Thorough agitation of the spray liquid should continue during the entire spraying operation.
Note: Spray solution should NOT be left standing in the vat overnight.

As formulations of other manufacturers' products are beyond the control of Syngenta and water quality varies with location, all mixtures should be tested prior to mixing commercial quantities.

Summer Crops
Heavy rains immediately following an application tend to result in excessive concentrations of herbicide in the seed furrow, thus encouraging possible crop injury. This is most likely to occur when a pre-plant or pre- emergence application is made using rates in excess of 2 kg/ha. To avoid the likelihood of herbicide injury follow time of application (a), (b) or (d) listed below.
Time of application
Broom millet, maize, saccaline, sorghum, sweet corn
Pre-plant or pre-emergence applications are preferred where grasses are the major problem.
- Pre-plant application followed by post-emergence application: Apply after establishment of the seed bed and up to 2 weeks prior to sowing. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist. If using this technique on irrigated crops, then a post-emergence spray must be applied as soon as possible after the crop has emerged and has developed 2 to 3 leaves.
- At sowing application followed by a post-emergence application: Apply at or immediately after planting and before crop and weeds emerge. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist. If using this technique on irrigated crops, then a post-emergence spray must be applied as soon as possible after the crop has emerged and has developed 2 to 3 leaves.
- At sowing application: Apply at or immediately after planting and before crop and weeds emerge. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist.
- Post-emergence application: Application must be made to seedling broadleaf weeds and grasses when they are not more than 1 cm high. Normally the crop is then at the 2 to 3 leaf stage. For best results, the soil should be moist and rain or irrigation should follow application. Add a non-ionic surfactant for all post-emergence applications in broom millet, saccaline and sorghum, and a crop oil at the recommended rate to the spray mixture for maize and sweet corn.

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.
