| Overview |
A pre-emergent and post-emergent herbicide for the control of annual grasses and broadleaf weeds in a range of crops, Pinus radiata plantations and for use in triazine tolerant canola. |
| Chemical Group |
triazine |
| General Instructions |
This product can be used both pre and post emergent to selectively control weeds in the crops listed in the directions for use table and in
Pinus radiata plantations. It can also be used to control weeds in Triazine Tolerant Canola varieties Established perennial species, large
annual and large broadleaf weeds will not be controlled at the rates recommended. Duration and effectiveness of control depends on the amount
of chemical applied, soil type, rainfall, weed species and other conditions.
Sufficient moisture (either rainfall or irrigation) is
required to move the product into the root zone of weeds to make the product effective. This should occur within 10 days of application to
ensure product effectiveness.
The maximum rate of application in all crops except forestry will be 3.0 kg ai per hectare per year (ie 3.3
kg product per hectare per year). The maximum rate in plantation forestry will be 4.5 kg ai/ha per year (5 kg product per hectare per year) in
sandy soils and those defined as highly erodible, and 8 kg ai/ha per year (8.9 kg prodUct per hectare per year) in clay loams and heavier
textured soils.
Integrated Weed Management Strategy for TT Canola
The use of this product in TT canola is subject to an 'Integrated Weed Management Strategy' for the use of triazine hel1licides in TT canola. The Strategy encompasses:' Integrated Weed Management' the specific management of crop plant volunteers and outcrossing to other plants; and triazine hel1licide residue management (agronomic and environment). Compliance with registered label directions and adoption of the principles outlined in the Strategy will assist with implementation of crop management practices that minimise the development of herbicide resistance in
treated weedSj reduce the levels of triazine residues in the environment; and manage volunteer plants and outcrossing. Copies of the Strategy are available from Sipcam representatives or by contacting Sipcam Pacific Australia Ply Ltd, Suite 11, 23-31 Gheringhap Street, Geelong VIC
3220 phone: (03) 5223 3746 or fax (03) 52233756. Where specific information and farm management assessment is required to assist with
application of Integrated Weed Management programs on-farm, particularly in adapting strategies to local conditions, then specific expert
advice should be obtained from an appropriate agronomist, consultant, chemical supplier or Departmental adviser. To minimise herlJicide
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 Sipcam Simazine 900 WDG or Sipcam Atrazine 900WG plus trifluralin
pre-emergence. Afollow-up with a Group Ahel1licide (if ryegrass is susceptible) or Sipcam Atrazine 900WG may be necessary. Broadleaf Weeds
only: Use Sipcam Atrazine 900WG post-emergence.
- DO NOT use Sipcam Atrazine 900WG or Sipcam Simazine 900 WDG if the area to be treated had
atriazine hertlicide applied to it last season.
- Watch for escapes, especially in paddocks with a long history of Group Chel1licide
use.
- DO NOT use Group Chel1licides in consecutive years. Resistant Weeds Reporting
Growers should collect plant or seed samples where
weeds that are normally susceptible to atrazine and sirnazine may be resistant, get them tested and seek professional advice.
To avoid
Triazine carry-over:
On acid soils (pH less than 6.5) - The maximum rate of Sipcam Sirnazine 900 WDG or Sipcam Atrazine 900WG or a
combination of the two products to be applied to the crop during the growing season is 2.2 kg/ha.
On allealine soils (pH greater than 6.5)
- The maximum rate of Sipcam Simazine 900 WDG or Sipcam Atrazine 900WG or a combination of the two products to be applied to the crop during
the growing season is 1.1 kg/ha.
Post-emergence use - It is recommended that Sipcam Atrazine 900WG only be used, and at rates of 1.1 kg/ha
or less, on both acid or alkaline soils.
Mixing
Do not mix/load or apply within 20m of any well, sink hole, intermittent or perennial stream. Partially fill the spray tank with water and
maintain agitation while adding the required quantity of Sipcam Atrazine 900WG. Ensure thorough mixing and agitate while spraying. If spray is
allowed to stand, agitate thoroughly before resuming spraying. If spray is allowed to stand, agitate thoroughly before resuming spraying.
Compatibility
This product is compatible with 2,4-0 Amine, diuron, paraquat and paraquatldiquat mixtures. It is advisable that a small scale compatibility
test be carried out prior to tank mixing with other products. In sugar cane only, the addition of Sodium 2,4-D will assist in short term
suppression of Nutgrass and other sedges.
Warning
Sorghum, Broom millet, saccaline
Heavy rain immediately after application may result in excessive concentrations of hel1licide in the seed
furrow, encouraging crop injury. This is most likely to occur in pre-plant or pre-emergence applications using rates in excess of 2kg/ha. To
avoid the likelihood of herbicide injury use technique (a), (b) or (d) in the Method of Application table.
Do not use as a pre-emergence
application in the wet season in the northern irrigation areas of Western Australia. When sowing is made on the flat avoid application to
ridged soil. Applying the total amount of product as a pre-emergence application will increase the risk of crop injury in the event of heavy
rain after application.
Maize, Sweet Corn
For post-emergent application add crop oil at the rate of 5.5Uha if grass weeds are a
problem. Ensure that the mixture is continually agitated. Do not apply mixtures of crop oil to stressed crops, inbred lines or breeding stock
as injury may occur.
If only broadleaf weeds are a problem, add 135mL of a 100% non-ionic surfactant per 100L of spray mixture.
Application
Application can be made by low volume boom or by aircraft. (except in TT canola). DO NOT use human f1aggers in aerial spraying, unless
protected by engineering controls such as enclosed cabs. Suggested minimum volumes of spray mixture per hectare are:
Boom:
Pre-plant I
Pre-emergence 55L
Post Emergence 110L
Air:
Pre-Plantl Pre-Emergence 15L
Post Emergence 22L
Application can be made as an
overall spray or as a band spray. Minimum band width should be 30cm. TT canola - DO NOT apply to TT canola by aircraft. Apply only with a low
volume 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 or where run-off may be captured by
farm earthworks.
Incomoratjon (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 thororouhly 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 this product may result in some weed growth. In flood or furrow irrigation situations complete and continued activation of the
product due to athin hard 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 em deep is required to ensure the irrigation water activates the product.
Always apply the product to an even unridged seedbed.

DO NOT use as a pre-emergence application in sorghum, broom millet, or saccaline during the wet season in the Northern irrigation areas of Western Australia.
SOIL MOISTURE: This product requires rainfal or irrigation to move it down 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. |
| Resistance Warning |
Sipcam Atrazine 900WG Herbicide is a member of the triazines group of herbicides. Sipcam Atrazine 900WG Herbicide has the inhibitor of photosynthesis at photosystem II mode of action. For weed resistance management Sipcam Atrazine 900WG Herbicide is a Group C Herbicide. Some naturally occurring weed biotypes resistant to Sipcam Atrazine 900WG Herbicide 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 Sipcam Atrazine 900WG Herbicide or any other Group C herbicide. Since the occurrence of resistant weeds is difficult to detect prior to use, Sipcam Pacific Australia Ply Umited accepts no liability for any losses that may result from the failure of Sipcam Atrazine 900WG Herbicide to control resistant weeds. RE-ENTRY PERIOD - Do not enter treated areas without protective clothing until spray has dried. |
