SUBTERRANEAN CLOVER, ESTABLISHED LUCERNE, PERENNIAL GRASS PASTURES
Weeds: Rat's Tail Fescue, Sand Fescue, Squirrel-tail Fescue, Vulpia (Silvergrass)

Rate/ha: 830 mL to 1.3 L
Critical Comments: Apply 6 to 10 weeks after emergence of the pasture, but not before the 3rd trifoliate leaf stage of subterranean clover. Best results are obtained from application to young, well grazed and actively growing plants. Some damage to subterranean clover may occur especially at the higher rates. DO NOT apply to sandy soils and use the lower rates on light textured soils. Apply under moist soil conditions, rain following application enhances results. DO NOT apply to stressed plants. Insect infestations should be controlled and subterranean clover allowed to recover before the GESATOP 600 SC is applied. DO NOT use herbicides for broadleaf weed control within 3 weeks of application.
State: NSW, Vic, ACT only
Rate/ha: 830 mL to 1.25 L plus 100 to 160 mL Gramoxone® 250 Herbicide
State: SA only
Rate/ha: 625 to 830 mL plus 100 to 160 mL Gramoxone 250
Critical Comments: Apply 6 to 10 weeks after emergence of the pasture, but not before the 3rd trifoliate leaf stage of subterranean clover. Best results are obtained from application to young, well grazed and actively growing plants. However, the addition of Gramoxone 250 improves the control of well established plants. Add a non- ionic surfactant at 0.2% v/v (200 mL/100 L).
Under conditions of good soil moisture, control of other grasses and some broadleaf weed seedlings may occur. DO NOT apply to sandy soils and use the lower rates on light textured soils. Apply under moist conditions, rain following application enhances results. DO NOT apply to stressed plants. Insect infestations should be controlled and subterranean clover allowed to recover before the GESATOP 600 SC plus Gramoxone 250 is applied. DO NOT use herbicides for broadleaf weed control within 3 weeks of application.

Weeds: Rat's Tail Fescue, Vulpia (Silvergrass)
State: WA only
Rate/ha: 625 to 830 mL
Critical Comments: Apply within 8 weeks of emergence of subterranean clover and grasses. Under conditions of good soil moisture control of other grasses and some broadleaf weeds may occur. Ensure that there is a good stand of subterranean clover present before spraying. Use the lower rate on light textured soils. DO NOT use with broadleaf weed herbicides within 3 weeks of using GESATOP 600 SC. DO NOT tank mix with other herbicides or add crop oils or wetting agents. DO NOT use on medics, or red or white clover. DO NOT overlap when spraying, otherwise damage may be observed.

GENERAL INSTRUCTIONS
GESATOP 600 SC is a pre-emergence herbicide which selectively controls certain broadleaf weeds and grasses in almonds (SA only), asparagus, berry fruit, canola (triazine tolerant varieties only), chickpeas, citrus, faba beans, gladioli, hops, lupins, pome fruit, roses and vineyards. In other crop areas, applied at higher rates, it will provide long control of a wide range of weeds and grasses. Established perennial species are not satisfactorily controlled.
Since the product enters weeds mainly through their roots, its effectiveness depends on rainfall or irrigation after application to move it down into the weed root zone.
Duration and effectiveness of control depends on the amount of chemical applied, soil type, rainfall and particular weed species. When susceptible weeds start to appear uniformly, the GESATOP 600 SC residue has probably dissipated.

Resistant Weeds Warning
Flowable GESATOP 600 SC Liquid 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 is a Group C herbicide. Some naturally occurring weed biotypes resistant to GESATOP 600 SC 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 GESATOP 600 SC 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 GESATOP 600 SC 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.
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 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 3.3 L/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 1.7 L/ha.
Post-emergence use: It is recommended that Gesaprim only be used, and at rates of 1.7 L/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 GESATOP 600 SC on TT-Canola.

Mixing
Settling may occur after storage for some weeks. Stir product or invert container several times before opening. Pour the product into the spray vat through a strainer to remove any dry particles or flakes, which can occasionally occur under hot storage conditions. Add the full quantity of GESATOP 600 SC to the partly filled spray tank while agitating. Fill tank and agitate to ensure thorough mixing. Continue agitation while spraying. Agitate vigorously from the bottom if allowed to stand. Reseal part used container immediately.

Compatibility
GESATOP 600 SC is compatible with Gesagard 500 SC. It can also be applied with Gramoxone 250, Reglone® Non-Residual Herbicide, Roundup* or Spinnaker*, provided the mixture is agitated. If allowed to stand, agitate vigorously.

Application
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.
