GENERAL INSTRUCTIONS
RELYON SIMAGEN 900 WG HERBICIDE is a pre-emergent herbicide, which is most effective when applied to bare, moist soil. Because it acts mainly through the roots of weeds, best results are obtained when rain or irrigation move the herbicide down to the root zone within two weeks of application. The duration and effectiveness of control depends on the amount applied, the type of soil, intensity of leaching and species of weeds present.

Integrated Weed Management Strategy for TT-Canola
An Integrated Weed Management Strategy for TT-Canola (the Strategy) has been developed and funded by the Canola Association of Australia in co-operation with certain companies. The Strategy is available from 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 RELYON SIMAGEN 900 WG HERBICIDE on TT-Canola.

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 RELYON SIMAGEN 900 WG HERBICIDE or Atrazine 900WG Herbicide plus Trifluralin pre-emergence. A follow-up with a Group A herbicide (if ryegrass is susceptible) or Atrazine 900WG Herbicide may be necessary.

  • Broadleaf Weeds only: Use Atrazine 900WG Herbicide post-emergence.

• DO NOT use Atrazine 900WG Herbicide or RELYON SIMAGEN 900 WG HERBICIDE 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 Atrizinr 900WG Herbicide or RELYON SIMAGEN 900 WG HERBICIDE or a combination of the two products to be applied to the crop during the growing season is 2.2kg ai/ha. On alkaline soils (pH greater than 6.5) – The maximum rate of Atrazine 900WG Herbicide or RELYON SIMAGEN 900 WG HERBICIDE or a combination of the two products to be applied to the crop during the growing season is 1.1kg ai/ha. Post-emergence use - It is recommended that RELYON SIMAGEN 900 WG HERBICIDE only be used, and at rates of 1.1kg ai/ha or less, on both acid or alkaline soils.

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.

MIXING

• Part fill tank with CLEAN water (50%).

• Commence vigorous agitation.

• Add granules steadily. DO NOT dump.

• Ensure complete dispersion before filling to volume with water.

• Continue agitation during spraying.

• DO NOT leave spray solution in tank overnight.

APPLICATION
Use a boom sprayer or a knapsack sprayer for small areas. 50–200L of mixture per hectare should be applied with the boom, and a minimum equivalent to 500L per hectare through the knapsack sprayer. Clean spray equipment immediately after use using Spray-Sure Spray Tank Cleaner.

TT-Canola: Application
DO NOT apply to TT-canola by aircraft. Apply only with a low boom sprayer with a 60m buffer zone downwind of treated fields to natural or impounded lakes or dams, and a 20m buffer zone for any well, sink hole, intermittent or perennial stream. Apply only to areas where run-off is unlikely to occur to where run-off may be captured by farm earthworks.

COMPATIBILITY
This product may be mixed with amitrole, Atrazine 900WG Herbicide, diuron, glyphosate, diquat and paraquat-diquat mixtures. Because products may vary from time to time, a small scale compatibility test should be carried out before mixing in the spray tank. For residual control of annual weeds in non-crop areas, pome and citrus and vineyards, mixtures of this product and glyphosate may be used. Half fill the spray tank with clean water before adding this product at the recommended rate and mix thoroughly. Then add 360g/L glyphosate product at 3L/ha or 700mL/100L and the remaining water. Maintain adequate agitation and use the mixture promptly. DO NOT use lower rates of glyphosate (360g/L) where control of perennial weeds is desired.

Araucaria, Corymbia, Eucalyptus and Pinus Plantations:
Field trials and use experience has indicated that the following species are tolerant. Test tolerance before treating other species.

SOIL MOISTURE
If sufficient rain to thoroughly wet the soil through the weed root zone has not fallen within 14 days of application, water in with the equivalent of 13mm of rain. If applied under dry conditions and irrigation is not available, mechanical incorporation to a depth of not more than 4cm within 7 days of sowing may assist results.

Resistance Warning: RESISTANT WEEDS WARNING
GROUP C HERBICIDE RELYON SIMAGEN 900 WG HERBICIDE is a member of the Triazines group of herbicides. Simazine has the inhibitors of photosynthesis at photosystem II mode of action. For weed resistance management Simazine is a Group C herbicide. Some naturally occurring weed biotypes resistant to Simazine 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 Simazine or other Group C herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Nutrien Ag Solutions Limited accepts no liability for any losses that may result from the failure of Simazine to control resistant weeds.
