ASSOCIATE

APVMA Code :46361 Active Constituent(s): 600g/kgmetsulfuron-methyl

Registered For Commercial Use Domestic Use Overview Associate is an easy to handle, measure and mix, highly active dry flowable formulation for the control of many broadleaf weeds in winter cereals. It can be applied any time from the three-leaf stage of the crop - when weeds are young and actively growing - to before booting. Associate is compatible with a wide range of grass and broadleaf herbicides, making weed control even more cost-effective with one-pass application. Recommended Uses Associate may be used in wheat, barley, triticale and cereal rye applied either alone or in mixtures post-crop and weed emergence. Associate may also be used with glyphosate herbicide for fallow pre-plant knockdown weed control. Refer to label for all instructions and directions for use. Benefits Highly active dry flowable granular formulation; Disperses quickly and completely in the spray tank; Broad spectrum broadleaf weed control in cereals; Compatible with certain grass and broadleaf herbicides; Compatible with knockdowns in fallow pre-plant situations. Mode of Action Associate belongs to a group of herbicides called sulfonylureas. Associate works by rapidly inhibiting plant cell division and plant growth. Chemical Group sulfonylurea General Instructions Associate is a selective systemic herbicide which is adsorbed through the roots and foliage with rapid translocation acting by inhibiting cell division in meristems thus stopping growth. Some crops are extremely sensitive to low concentrations of this product. See "Sprayer Clean-up" section. Where treatment is delayed or where weeds are not actively growing due to adverse conditions, results may be slow to appear and weeds may only be stunted or suppressed. Instructions specific for cereals: With the exception of the preplant weed control recommendations, apply at the early post emergence stage of the crop (3 leaf to before booting) when weeds are small (i.e. no greater than 5cm in height or diameter) and actively growing. Best weed control is obtained when rainfall wets the soil to a depth of 5 to 7.5cm within 4 weeks of application. Where treatment is delayed or where weeds are not actively growing due to adverse conditions, results may be slow to appear and weeds may be only stunted or suppressed (eg. Indian Hedge Mustard). Associate will remain in the soil for a period of time (see Crop Rotation Recommendations). The persistence of Associate in the soil is dependent on various environmental conditions e.g. soil pH, temperature, soil moisture and organic matter. Wet, warm, acid soils high in organic matter favour breakdown of Associate in the soil. It should be noted that Associate does not provide a commercially acceptable level of soil residual weed control. Crops other than wheat, barley, triticale and cereal rye may be extremely sensitive to low concentrations of Associate residues in the sprayer or in the soil. See "Sprayer Clean-up" and "Crop Rotation Recommendations". The recommendation of the addition of Associate to Nufarm Glyphosate CT and Weedmaster 600 CT as a pre-plant knockdown is to enhance the control of certain broadleaf weeds (e.g. doublegee, sorrel, erodium, clover, medic and soursob) and to help prevent (or at least minimise) the risk of resistant weeds occurring. Its purpose is not to provide residual control of weeds. Instructions specific for brush and herbaceous weed control: Apply when bushes/plants are actively growing. Where treatment is delayed or bushes/plants are not actively growing due to adverse conditions (such as a period of prolonged dry weather) or if partial spray coverage occurs, results may be slow to appear and subsequent regrowth may occur. Should regrowth occur, re-treatment at the recommended rate is advised. Re-treatment of blackberries should only be undertaken once regrowth has reached one (1) metre tall - this may not be until two (2) years after the initial application. For control of bushes previously sprayed with other brush control herbicides or for bushes which may have been burned or slashed ensure two (2) years has elapsed. Due to the widespread picking of blackberries by the public, it is recommended that the product is not applied to bushes bearing mature fruit. Instructions specific for treatment of pasture or pasture renovation: Allow weeds to recover from grazing before application. Docks and Sorrel in particular require fresh leaf growth for adequate uptake of chemicals. Legumes will be removed from pasture if oversprayed with Associate. Some grasses will be damaged in pasture sprayed with the product and biomass production may be reduced for several months. Associate used on established Perennial Phalaris and/or established Perennial Cocksfoot may cause temporary yellowing and some stunting. Associate can severely damage Annual and Perennial Ryegrass. Associate does not control/damage Silvergrass (Vulpia spp.), Brome Grass (Bromus spp.) or Winter grass (Poa spp.). Sorrel seedlings may germinate after the break in the following year, particularly after cultivation. The ungerminated clover seed bank is not affected by Associate application. Clover vigour is often increased in the year following application where seed banks are reasonable. The seed set of clover in the year Crop Safety DO NOT use in winter cereal crops undersown with legume pasture species, e. g. medics, clovers. DO NOT apply to wheat varieties King, Jacup, Milling and Harrier. Care should be taken if it is intended to apply Associate in the same season to a crop already treated with another sulfonylurea herbicide as crop damage may occur. Consult your local agronomist or Nufarm representative. DO NOT apply other sulfonylurea herbicides in a tank mix with Associate as a pre-plant application. Use of this product on land having a soil pH of 5.5 or less may result in some crop retardation, particularly if the crop is stressed - see comment in point below. DO NOT apply to crops that are stressed by any cause (such as severe weather conditions, drought, waterlogging, excessive soil acidity or alkalinity, poor nutrient status, disease, nematode or insect damage) as crop injury may result. When treatment is followed by severe stress (such as drought, prolonged cold, waterlogging or frosty conditions) crop yellowing and growth retardation may occur. Crops normally recover without loss in yield. Disease, nematode or insect damage following application may also result in crop injury. Spray Preparation Associate is a dry flowable formulation to be mixed with water and applied as a spray. Partially fill the spray tank with water. Using the Associate measuring cone provided, measure the amount of Associate required for the area to be sprayed. Add the correct amount of Associate to the spray tank with the agitation system engaged. Top up to the correct volume with water. THE MATERIAL MUST BE KEPT IN SUSPENSION AT ALL TIMES BY CONTINUOUS AGITATION. When prepared spray solution has been allowed to stand, thoroughly re-agitate before using. In tank mixes Associate must be in suspension before adding the companion herbicide or surfactant. For application of Associate in liquid fertiliser, slurry the Associate in water then thoroughly mix the slurry into the liquid fertiliser. Check compatibility before mixing Associate in fertiliser solutions. DO NOT add a surfactant/wetting agent. Compatibility Associate is compatible with the commonly used broadleaf herbicides Agtryne*, Bromicide MA, Kamba 500, Broadstrike, Eclipse, Nufarm Diuron (liquid Flowable and 900DF), Igran/ Terbutryn 500, Jaguar*, Lontrel*/Archer?, Nufarm LVE MPCA, Nufarm MCPA 500, Metribuzin, Starane*, Nugrex/ Tigrex*, Tordon*242, Tordon*75-D, Nufarm Trooper, Nufarm Amicide 625 and non-selective glyphosate herbicides (e.g. Glyphosate CT and Roundup PowerMAX). Associate is compatible with the commonly used insecticides chlorpyrifos and omethoate (e.g. Comrad). Some increased temporary crop yellowing may occur when Associate is applied as a tank mix with these insecticides. To extend the weed range, add Nufarm MCPA 500, Nufarm Amicide 625, Nufarm Diuron (Flowable and DF) and Terbutryn at label rates (Vic. only). The compatibility of Associate with grass herbicides varies between products and weed species (refer following table). View Document Mixtures NOTES ON ASSOCIATE/DICLOFOP METHYL BASED PRODUCTS OR ASSOCIATE/TRISTAR MIXTURES. -Nufarm Associate Herbicide and diclofop methyl based products or Tristar Advance can be tank mixed, but when this mixture is used, some reduction in grass weed control can be expected. -For heavy infestation of grass weeds, control may be inadequate - Vic. and Tas. only. -Significant reduction in grass weed control should be expected - SA only. -Nufarm Associate Herbicide and diclofop methyl based products or Tristar Advance are not a recommended mixture because they result in significant reduction in grass weed control and/or crop damage - WA only. -Consult company representatives for further information or advice. Use of Surfactant/Wetting Agent Instructions specific for cereals: Always add a nonionic surfactant (1000g. ac/L) at 100mL/100L of final spray volume (0.1% volume/volume). The use of spraying oils is not recommended. Note: Do not add a surfactant/wetting agent when Associate is tank mixed with Nufarm Terbutryn/ Igran or Nufarm Diuron (Flowable and DF). Instructions specific for brush and herbaceous weed control: If a specific surfactant/wetting agent is not listed in the Directions for Use table, or when mixing glyphosate use a non-ionic surfactant (1000 gac/L) at 100mL/100L of final spray volume (ie 0.1% volume/volume). When an organosilicone penetrant (Pulse) is recommended in the Directions for Use table and with all gasgun applications, use 10mL/5L or 200mL/100L of final spray volume (ie 0.2% volume/volume). When a mineral spray oil (eg Caltex Sprayplus*) is recommended in the Directions for Use table, use 1L/100L of final spray volume (ie 1% volume/volume). Instructions specific for treatment of pasture and pasture renovation: Always add a non-ionic surfactant a (1000g ac/L) eg Chemwet 1000 at 200mL/100L of final spray volume (0.2% volume/volume). Boom Spray Application Use a boom spray property calibrated to a constant speed and rate of delivery to ensure thorough coverage and a uniform spray pattern. Adjust boom height to ensure correct spray overlap. Avoid spraying where drift can go onto crops, are likely to be planted to crops and non target pastures as injury may occur. Avoid overlapping and shut off spray booms while starting, turning, slowing or stopping as injury to the crop may result. Cereals: Apply a minimum of 50L prepared spray/ha. Pasture: Apply a minimum of 70L prepared spray/ha. Other use patterns: Apply in a minimum of 150L prepared spray/ha. Increase to 200L prepared spray/ha or more in dense stands. Aerial Application Avoid spraying in still conditions and in winds likely to cause drift onto adjacent sensitive crops or fallow areas likely to be planted to these crops - see Crop Rotation Recommendations. Turn off spray boom whilst passing over creeks and dams. DO NOT apply when a temperature air inversion is likely to occur. Use of Micronair equipment is not recommended due to greater drift potential. Apply in a minimum of 20L/ha water. Application in a higher water volume of 30L/ha will improve the reliability of weed efficacy. Other use patterns: - helicopter only Apply in a minimum of 100L per ha on Blackberries or 60L per ha on Mimosa pigra and up to 200L prepared spray/ha. Higher water volumes may be necessary to ensure adequate coverage where bushes are large and terrain is steep. Spray with a properly calibrated helicopter using the half overlap opposite pass technique. Handgun Application Pastures and Other use patterns Spray foliage and canes until wet. Ensure coverage is uniform and complete. Use pressures of 550-750 kPa (80 - 100psi) depending on target species and size of bush. Use larger nozzles and higher pressures for largest bushes. Example: Size No. 4 or 5 spray nozzle: small individual bushes or broadleaf weeds - less than 1m high Size No. 5 or 6 spray nozzle: medium sized bushes - 1.2m high Size No. 7 or 8 spray nozzle: large bushes 2-3m high or of a large diameter Note: Use large spray nozzle/high volume for blackberry regrowth. Spray using a wide cone setting as much as possible. Use even, side-by-side spray pattern moving up from the base to the top of the bush as leaves are wet. For blackberries, do not ignore runners to the side or the top of the bush and ensure spray penetrates larger bushes to wet foliage and canes. Gas Gun Application Pastures and Other use patterns Apply to ensure good coverage of all foliage is achieved. The use of a suitable marker dye is recommended. eg Spraymate Spray Marker Dye. SPRAYER CLEAN-UP Immediately after spraying thoroughly remove all traces of Associate from mixing and spray equipment as follows: 1. Drain tank, then flush tank, boom and hoses with clean water for a minimum of 10 minutes. 2. Fill the tank with clean water then add 300mL household chlorine bleach (containing 4% chlorine) per 100L of water. Flush through boom and hoses then allow to stand for 15 minutes with agitation engaged, then drain. 3. Repeat step 2. 4. Nozzle and screens should be removed and cleaned separately. To remove traces of chlorine bleach, rinse the tank thoroughly with clean water and flush through hoses and boom. Caution DO NOT use chlorine bleach with ammonia. All traces of liquid fertilizer containing ammonia, ammonium nitrate or ammonium sulphate must be rinsed with water from the mixing and application equipment before adding chlorine bleach solution. Failure to do so will release a gas with a musty chlorine odour which can cause eye, nose, throat and lung irritation. DO NOT clean equipment in an enclosed area. Crop Rotation The use of Associate may prevent early reestablishment of legumes and grasses after treatment. The period that residues persist in the soil will vary according to site conditions such as climate, soil pH, presence of soil microorganisms, soil temperature, soil moisture and the rate used. Breakdown is fastest in warm wet acid soil and slower in cold dry alkaline soils. Land previously treated with Associate should not be rotated to crops other than those listed in the table following. Tolerance of other crops (grown through to maturity) should be determined on a small scale before sowing into larger areas. The Associate treated area may be replanted to any of the specified crops after the interval indicated in the following table: View Document View Document Restraints DO NOT store a suspension of Associate for more than two days otherwise significant breakdown will occur. DO NOT apply to crops under stress. DO NOT store tank mixes of Associate. DO NOT apply if rainfall is expected within 2 hours (for Woody Weeds 4 hours). DO NOT use on furrow or flood irrigated crops. DO NOT apply before the three leaf stage of the crop when used for post emergent weed control. DO NOT treat newly sown pastures as severe damage may occur. DO NOT use on pasture seed crops. DO NOT apply to weeds that are under stress or not actively growing. Resistance Warning Nufarm Associate Herbicide ("Associate") is a member of the Sulfonylureas group of herbicides. Associate has the inhibitors of acetolactate synthase mode of action. For weed resistance management Associate is a Group B herbicide. Some naturally-occurring weed biotypes resistant to Associate and other Group B herbicides of acetolactate synthase 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 Associate or other Group B herbicides. Some populations of Annual Ryegrass and a few broadleaf weeds are already known to be resistant to Associate and other ALS inhibitor herbicides. Since the occurrence of resistant weeds is difficult to detect prior to use, Nufarm Australia Limited accepts no liability for any losses that may result from the failure of Associate to control resistant weeds. To prevent, or at least minimise the risk of resistant weeds occuring, use Associate in tank mixes (if appropriate) and/or rotations with herbicides having different modes of action effective on the same weed species. Large numbers of healthy surviving weeds can be an indication that resistance is developing. Efforts should be taken to prevent seed set of these survivors. DO NOT apply Associate alone for fallow and preplant knockdown weed control. DO NOT make more than one application of an ALS inhibitor herbicide to a crop, either preplant, incorporated-by-sowing or post crop and weed emergence. If the user suspects that an ALS inhibitor resistant weed is present, Associate or other ALS inhibitor herbicides should not be used.Strategies to minimise the risk of herbicide resistance are available. Consult your farm chemical supplier, consultant, local Department of Agriculture or Primary Industries, or local Nufarm representative. Protection of wildlife, fish, crustaceans and environment DO NOT contaminate streams, rivers or waterways with the chemicals or used containers. Protection of crop, native and other non-target plants Injury to or loss of desirable trees or vegetation may result from failure to observe the following: 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 or allow spray to drift onto adjacent crops and non-target desirable plants, or onto agricultural land scheduled to be planted to other crops as injury to the crop may occur. Safety Directions May irritate the eyes and skin. Avoid contact with eyes and skin. Do not inhale dust and spray mist. After use and before eating, drinking or smoking wash hands, arms and face thoroughly with soap and water. Storage KEEP OUT OF REACH OF CHILDREN. Store in the closed, original container in a dry, cool, well ventilated area, out of direct sunlight. Disposal Triple or preferably pressure rinse containers before disposal. Add rinsings to spray tank. Do not dispose of undiluted chemical 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. Product details last updated on 01 Oct 2009
