GENERAL INSTRUCTIONS
ACP Terbuthylazine 875 WG Herbicide can be used to selectively control weeds in the crops listed in the directions for use table and on fallows prior to establishing crops as directed in Fallows section below. When applied pre-emergence, the product is mainly absorbed through the roots. Weeds buried by cultivation may not be effectively controlled. Heavy rainfall on light soils may cause movement of the herbicide out of the weed seed zone, resulting in reduced weed control. Do not apply to recently burnt stubble/trash. After burning, rainfall or cultivation is required to allow ACP Terbuthylazine 875 WG Herbicide to reach the soil and not be irreversibly bound by ash. Sufficient rainfall (20 to 30 mm either rainfall or irrigation) to wet the soil through the weed root zone is necessary within 2 to 3 weeks of application to make the product effective. Delay in activation of this product may result in some weed growth. Results can be variable if seasonal conditions are dry prior to sowing and crops are sown into a dry or low moisture seedbed. Where soil has a high potential for leaching, heavy rainfall between application and crop emergence may result in crop damage from movement of herbicide into the crop seed zone. 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 4cm deep is required to ensure the irrigation water activates the product. Always apply the product to an even un-ridged seedbed. Dense weed populations and multiple germinations (especially Wild radish) may require both a pre-emergent and post emergent herbicide treatment (only one being ACP Terbuthylazine 875 WG Herbicide) to give acceptable control.

APVMA Compliance Instructions for Mandatory COARSE or Larger Droplet Size Categories
Important Information
These instructions inform users of this chemical product how to lawfully comply with the requirement of COARSE or larger spray droplet size category for spray application. Spray droplet size categories are defined in the ASAE S572 Standard (newer name may also be shown as ASABE) or the BCPC guideline. Nozzle manufacturers may refer to one or both to identify droplet size categories, but for a nozzle to comply with the requirement, the manufacturer must refer to at least one. Complying with the label requirement to use a specific droplet size category means using the correct nozzle that will deliver that droplet size category under the spray operation conditions being used. The APVMA has approved only the following specific methods for choosing the correct nozzle. Use one of the methods specified in these instructions to select a correct nozzle to deliver a COARSE or larger droplet size category. The use of this product in TT canola is subject to the current approved “Integrated Weed Management Strategy for the use of triazine herbicides in TT canola”. The Strategy encompasses: Integrated Weed Management; the specific management of crop plant volunteers and outcrossing to other plants; and triazine herbicide 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 weeds; reduce the levels of triazine residues in the environment; and manage volunteer plants and outcrossing. 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 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.

• DO NOT use ACP Terbuthylazine 875 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.

Resistant Weeds Reporting
Growers should collect plant or seed samples where weeds that are normally susceptible to atrazine, simazine and terbuthylazine may be resistant, get them tested and seek professional advice.

MIXING
Do not mix or load within 20m of any well, dam, intermittent or perennial stream. Partially fill the spray tank with water and maintain agitation while adding the required quantity of ACP Terbuthylazine 875 WG Herbicide. Agitation should continue after filling and during spraying. If spray is allowed to stand, agitate thoroughly before resuming spraying.

COMPATIBILITY
This product is compatible with Acclaim® Herbicide, Starane Advanced Herbicide, Strada® Herbicide, Dual Gold Herbicide, Hasten* Spray Adjuvant, BS1000 non-ionic surfactant, Uptake* Spraying Oil, trifluralin, 2,4-D amine, Tordon75D, glyphosate, Roundup Ready Herbicide with Plantshield by Monsanto, Panida Grande, paraquat and paraquat/ diquat mixtures**. Refer to the label of the knockdown herbicide for specific weed by rate recommendations. Some reduction in control may be observed on some weeds compared to the application of knock-down herbicides alone, particularly on large weeds. It is advisable that a small scale compatibility test be carried out prior to tank mixing with other products. Read and follow all label directions, restraints, plant-back periods, withholding periods, regional use restrictions and safety directions for the tank mix products.

APPLICATION
DO NOT apply when wind speed is less than 3 and greater than 20 kilometres per hour or during weather conditions when surface temperature inversions can develop. Apply by ground boom only in a minimum of 50L/ha. Use only COARSE spray quality according to ASAE S572 definition for standard nozzles.

Pre-Sowing
ACP Terbuthylazine 875 WG Herbicide can be applied to either cultivated or un-worked soil up to 7 days prior to sowing. If cultivated, the soil should be relatively level before spraying and after sowing. For best results, apply to moist soil immediately before sowing and incorporate with combine or air-seeder which provides full soil disturbance to incorporate the ACP Terbuthylazine 875 WG Herbicide evenly. Pulse crops must be sown to at least 5cm. Where the crop is sown with minimum-tillage sowing equipment (fitted with knife points or blades less than 12mm wide and generally placed on 20cm tyne spacing) poor weed control may result in the furrows. For crop safety, maintain slow to moderate speed to avoid leaving deep furrows and avoid throwing soil into adjacent furrows. Sowing with disc seeds may lead to unacceptable crop damage in Pulse crops. At the higher rates in Pulse crops, avoid over-lapping sprays and spraying-out corners. Heavy rain after application onto ridged soil in particular may cause crop damage from ACP Terbuthylazine 875 WG Herbicide washed into the seed furrow.

Post Sowing Pre Emergence (PSPE)
Pulse crops must be sown to at least 5cm. Apply within 2 days of sowing to soil which is relatively flat after the sowing operation. Heavy rain after application onto ridged soil in particular may cause crop damage from ACP Terbuthylazine 875 WG Herbicide washed into the seed furrow. At the higher rates in Pulse crops, avoid over-lapping sprays and spraying-out corners. In Pulse crops sowing with disc seeders may lead to unacceptable crop damage.

Post Emergence
ACP Terbuthylazine 875 WG Herbicide can be applied to triazine tolerant canola up to 6-leaf stage and sorghum up to 5-7- leaf stage of the crop. Always add Hasten at 500mL/100L water.

Resistant Weeds Warning
ACP Terbuthylazine 875 WG Herbicide is a Group C herbicide belonging to the triazines group which is an inhibitor of photosynthesis at photosystem II. For weed resistance management ACP Terbuthylazine 875 WG Herbicide is a Group C Herbicide. Some naturally occurring weed biotypes resistant to ACP Terbuthylazine 875 WG Herbicide and other triazine 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 ACP Terbuthylazine 875 WG Herbicide or any other Group C herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Australis Crop Protection Pty Ltd accepts no liability for any losses that may result from the failure of ACP Terbuthylazine 875 WG Herbicide to control resistant weeds.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT
Very toxic to aquatic life. DO NOT contaminate wetlands or watercourses with the product or used containers. After application of ACP Terbuthylazine 875 WG Herbicide, DO NOT irrigate crop to the point of run-off, unless it can be retained on farm.

TT canola: DO NOT use or apply this product post-emergence on raised beds or where furrows have been created in the soil for the purpose or holding or channeling water. DO NOT use in channels or drains.

PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS
DO NOT apply or drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend or in locations where the chemical may be washed or moved into contact with their roots. DO NOT apply on sites where surface water from heavy rain can be expected to run off to areas containing, or to be planted with susceptible crops or plants. DO NOT plant crops other than those recommended on this label for at least 6 months following the most recent application of up to 1.2 Kg per hectare.
