ARCHER

APVMA Code :52139 Active Constituent(s): 300g/Lclopyralid(present as the triisopropanolamine salt)

Registered For Commercial Use Domestic Use Overview Archer is an ideal herbicide for the control of certain hard-to-kill broadleaf weeds and volunteer crops. It can be used during early crop development (from the 2-leaf stage), and is soft on all major cereal and canola varieties due to excellent selectivity. Archer is compatible with a wide range of selective grass and broadleaf herbicides, making weed control even more cost-effective with one-pass application.  Recommended Uses Archer may be used for pre-sowing, post-sowing pre-emergence, early and late post-emergence weed control in barley, oats, triticale, wheat; post-emergence control in canola, pastures, fallow land, forests, Pinus radiata plantations, rights-of-way and industrial situations. Refer to label for all instructions and directions for use. Benefits Prevents weed competition during early crop development; Excellent selectivity (soft an cereals and canola); Compatible with a wide range of selective grass and broadleaf herbicides; May also be used in combination with knockdown herbicides before sowing cereals (WA only). Mode of Action Archer belongs to a group of herbicides called pyridines. Archer works by disrupting plant cell growth. It translocates quickly throughout the plant and roots, accumulating in areas of high metabolic activity. This attribute enables Archer to effectively control even deep-rooted plants. Archer disrupts water intake, metabolism and translocation of nutrients. Plant leaves wither and lose their ability to function. Above ground portions dry up and die, and below ground, growing roots are destroyed and regrowth prevented. Target plants do not die immediately but they do stop growing and competing with the crop. General Instructions Mixing Half fill the spray tank with water and add the required quantity of Archer and complete filling. Agitate continuously to ensure thorough mixing before and during application. Only mix sufficient chemical for each day's work. Tank mixtures: Wettable powder or dry flowable formulations should be added to the spray tank first, followed by suspension concentrates (flowables), aqueous concentrates (Archer) and the emulsifiable concentrate formulation (eg. Verdict* 104 or MCPA LVE). Compatibility Archer is compatible with the following: BROADLEAF HERBICIDES: Starane, Associate/Brushkiller, Bromicide 200, Bromicide MA, Lusta, Nufarm Flowable Diuron, Nufarm Glyphosate CT, Credit plus Bonus, Roundup^ PowerMAX, Roundup CT, Weedmaster Duo, Nufarm MCPA 500, Nufarm LVE MCPA, Nuquat 250, Spray-Seed, terbutryn, Amicide 625. GRASS HERBICIDES IN CEREAL CROPS: Nugrass, Grasp, Puma (Grasp and Puma for wild oat control only) GRASS HERBICIDES ON BROADLEAF CROPS: Asset Application BOOM SPRAYING CROPS and PASTURES Apply Archer in sufficient water to obtain good coverage. If should be applied by an accurately calibrated ground rig or aircraft, delivering 200 to 300 micron droplets and not less than 50 L/ha water volume for boom sprayers or not less than 20 L/ha for aerial applications. Hardhead thistle - Use a spray volume of 200 to 250 L/ha of water. Silver wattle - Use a spray volume of 150 to 200 L/ha of water by ground boomspray and a minimum spray volume of 50 L/ha by aircraft. BOOM SPRAYING PLANTATION TREES: Appy ARCHER in sufficient water to obtain good coverage. It should be applied by an accurately calibrated ground rig or aircraft, delivery 200 to 300 micron droplets and not less than 50 L/ha water volume for boom sprayers or not less than 20 L/ha for aerial application. HIGH VOLUME HAND GUN Apply the recommended mix to give full coverage of leaves and stems through a No. 6-8 tip at 700 to 1500 kPa. Spray volume for effective coverage of dense two metre high silver wattle should be 30 to 40 litres of spray per 100 m2 (10 x 10) of infestation. For larger areas an equivalent would be 3000 to 4000 litres per infested hectare. Cleaning Cleaning Spray Equipment Rinse water should be discharged onto a designated disposal area or, if this is unavailable, onto unused land away from desirable plants and water courses. Partial Cleaning (before spraying other labelled or tolerant crops) After using Archer, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose. Quarter fill the tank with clean water and circulate through the pump, line, hoses and nozzles. Drain and repeat procedure twice. Complete Cleaning (before spraying susceptible crops) After using Archer, empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose. Quarter fill the tank with clean water and circulate as above, then drain. Quarter fill the tank again and add an alkaline detergent such as Nufarm Spraymate Tank & Equipment Cleaner according to the label directions and circulate throughout the system for at least fifteen minutes. Drain, remove filters and nozzles and clean separately. Rinse inside the tank thoroughly using a pressure hose and flush the system with clean water. Plant Back Period PLANTBACK PERIODS FOR SOUTHERN AUSTRALIA WINTER DOMINANT RAINFALL AREAS (Sth NSW, VIC, SA, WA): Required rain - A minimum 25 mm rain event in the post harvest summer to autumn period, with a subsequent extended period of at least 1 week where the top 10 cm of the soil stays moist is required to enable breakdown of soil residues. Fastest residue breakdown will occur under good soil moisture and warm conditions, which promote microbial activity. Where significant rain (>25 mm) has fallen in summer to autumn, with soil wetting for at least one week, the following plantback periods apply (table). PLANTBACK PERIODS FOR NORTHERN AUSTRALIA SUMMER DOMINANT RAINFALL AREAS (Nth NSW, QLD): Required rainfall before plantback: If planting susceptible summer crops - at least 100mm rain If planting susceptible winter crops - at least 150mm rain This rain or irrigation should wet the soil for extended periods (at least one week) this is essential for breakdown of soil residues prior to planting susceptible crops. If planting a cereal or canola crop - at least 50 mm of rain or irrigation is required to enable soil wetting for at least one week. Where these requirements have been met the following plantback periods apply (table). Note: Susceptible crops should not be sown for at least 2 years where Archer Herbicide at more than 300mL/ha has been used in northern Australia. View Document Protect Property DO NOT apply under weather conditions, or from spraying equipment that may cause spray drift onto nearby susceptible plants/crops, cropping lands or pastures. Composts and mulches - DO NOT apply Archer Herbicide to crops or pastures that will be used for the production of compost or mulches or mushroom substrate. Such compost or mulch made from plant material treated with Archer may cause damage to susceptible crops and plants. Susceptible crops and plants include, but are not limited to chickpeas, clover, cotton, faba beans, field peas, fruit trees, lentils, lupins, lucerne, medics, ornamentals, potatoes, safflower, tomatoes, vegetables, grape and kiwifruit vines, vetches, and wattles. Field peas, faba beans, lentils and vetches are particularly susceptible and should not be sown the season following an application of Archer at 500 mL/ha. Where Archer residue carry over from use rates of less than 500 mL/ha is suspected and susceptible crops are to be planted, test the treated area as follows: - Field bioassay - where rain allows, plant a small area of the susceptible crop 4 to 6 weeks before desired planting data and take note of any symptoms of injury. If any herbicide symptoms are observed, only plant either canola or a cereal (see recommendation for northern and southern Australia below). - Pot bioassay - where not practical to do field bioassay, plant a small number of seeds of the susceptible crop into pots containing soil from the treated field. Do this 4 to 6 weeks before desired planting date. If any herbicide symptoms are observed, only plant either canola or cereal (see recommendation for northern and southern Australia below). Stubble from treated crops - ensure that harvesters effectively spread crop straw and DO NOT leave a heavy 'header trail' after harvest. Burn (if legal in the area), bale and remove, slash or incorporate stubble as soon as practical after harvest and as long as possible before planting next year to allow microbial breakdown of any residues in straw. Heavy stubble loads may carry more residue into the following season. Where heavy stubble burdens and/or nonwetting soils exist and less than recommended rain amount have occurred from application to planting the susceptible crop (see below), only plant a winter or summer cereal or canola. Planting crops following use of Archer herbicide in previous crop - planting crops 'dry' without significant rain (see below) in the 'autumn break' increases the risk of injury to susceptible crops. This practice should be avoided, or only plant a winter or irrigated summer cereal crop or canola. In severely dry conditions, where less than 30% of average annual rainfall and/or less than the minimum rain (see below) has fallen between application and planting the next year, only plant a winter or irrigated summer cereal or canola. Restraints CROPS, PASTURES AND FALLOW LAND DO NOT apply to weeds which may be stressed (inactive growth) due to prolonged periods of extreme heat or cold, moisture stress (water logging or drought) or previous herbicide treatment as reduced levels of control may result. DO NOT spray if rain is likely within 3 hours. DO NOT apply immediately before sowing susceptible crops, or sow susceptible crops into paddocks treated the previous year with Archer until after the required plantback period has elapsed (see PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS section). DO NOT compost material from treated plants or crops before reading the PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS section. FORESTS DO NOT apply to weeds which may be stressed (inactive growth) due to prolonged periods of extreme heat or cold, moisture stress (water logging or drought) or previous herbicide treatment as reduced levels of control may result. DO NOT spray if rain is likely within 3 hours. Resistance Warning Archer Herbicide is a member of the Pyridine group of herbicides. Archer Herbicide has the disrupter of plant cell growth mode of action. For weed resistance management, Archer Herbicide is a Group I herbicide. Some naturally occurring weed biotypes resistant to Archer Herbicide and other Group I 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 Archer Herbicide or other Group I herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Nufarm Limited accepts no liability for any losses that may result from the failure of Archer Herbicide to control resistant weeds. Protection of wildlife, fish, crustaceans and environment Archer has low toxicity to fish, birds, honey bees, livestock, earthworms and aquatic organisms, however, DO NOT contaminate water with chemical or used container. Safety Directions May irritate the eyes and skin. Avoid contact with eyes and skin. DO NOT inhale the spray mist. When preparing the spray, wear elbow-length PVC gloves and a face shield. After use and before eating, drinking or smoking, wash hands, arms and face thoroughly with soap and water. After each day's use, wash face shield and contaminated clothing. Storage Store in the closed, original container in a cool, well-ventilated area. Do not store for prolonged periods in direct sunlight. Disposal Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemicals on site. If recycling, replace cap and return clean containers to recycler or designated collection point. If not recycling, break, crush or puncture and bury empty containers in a local authority landfill. If no landfill is available, bury the containers below 500 mm in a disposal pit specifically marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt. SMALL SPILL MANAGEMENT Wear appropriate clothing whilst cleaning up small spills, (see SAFETY DIRECTIONS). Apply absorbent material such as earth, sand or clay granules to the spill. Sweep up material for disposal when absorption is complete. Dispose of the contaminated material in accordance with STATE and/or LOCAL REGULATIONS. Product details last updated on 22 Jun 2009
