Sprayer Cleanup Many plant species are sensitive to SUREFIRE METSULFURON METHYL HERBICIDE. For this reason it is important to thoroughly clean spray tanks after use as small quantities of product remaining in the tank may cause injury to desirable pastures and crops if the tank is used for other spraying procedures. The following method of tank cleanup should be used:

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 20L of water. Flush through boom and hoses then allow to stand for 15 minutes with agitation engaged, then drain.
3. Repeat step 2.
4. Nozzles and screens should be removed and cleaned separately.
5. To remove traces of chlorine bleach, rinse the tank thoroughly with clean water and flush through hoses and boom.

WARNING: DO NOT use chlorine bleach with ammonia. It is important that liquid fertilisers containing ammonia be rinsed from the application equipment before adding a chlorine bleach solution. If traces of ammonia are present it may react with the chlorine bleach releasing a gas with a musty chlorine odour which can cause eye, nose, throat and lung irritation. DO NOT clean equipment in an enclosed area.

PROTECTION OF WILDLIFE, FISH, CRUSTACEANS AND ENVIRONMENT DO NOT contaminate streams, rivers or waterways with the chemicals or used containers. DO NOT apply to weeds growing in or over water. DO NOT spray across open bodies of water.

PROTECTION OF LIVESTOCK There is a nil withholding period for this product in pasture situations and stock may continue to graze where the product has been used in pasture situations. It is recommended that stock is removed from the pasture for 3 days to ensure product efficacy. Certain plants such as bracken are naturally toxic to stock. When toxic plants are present, it is recommended that grazinging be delayed until complete browning of treated plants has occurred.

PROTECTION OF CROPS, NATIVES 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 measured or moved into contact with their roots. DO NOT apply under weather conditions, or from spray equipment, that may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures.

STORAGE AND DISPOSAL Keep out of reach of children. DO NOT store the prepared spray for more than 2 days. DO NOT store near meals with other products. Store in the closed, original container in a cool, well ventilated area away from children, animals, food and feedstuffs. Do not store for prolonged periods in direct sunlight. 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 empty containers and deliver for appropriate disposal at an approved waste management facility. If an approved waste management facility is not 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 in compliance with relevant Local, State or Territory government regulations. Empty containers and product should not be burnt.

SAFETY DIRECTIONS Harmful if swallowed. Will irritate the eyes and skin. Avoid contact with eyes and skin. When opening the container and preparing the spray wear elbow length PVC gloves and goggles. If applying by hand wear chemical resistant clothing, buttoned to the neck and wrist, a washable hat and elbow length PVC gloves. If product on skin, immediately wash area with soap and water.

Notes on SUREFIRE METSULFURON METHYL Herbicide/Diclofop-methyl mixtures: a) Some reduction in grass weed control can be expected b) In heavily weed infested areas control may be inadequate (Victoria and Tasmania only) c) Significant reduction in grass weed control should be expected (SA only) d) Mixtures of SUREFIRE METSULFURON METHYL Herbicide and diclofop-methyl are not recommended in WA as these mixtures will result in significant reduction in grass weed control and/or crop damage.

Spray Preparation The product is a dry flowable granule which must be mixed with clean water.

1. Partially fill the spray tank with water.
2. With the agitation system engaged, add the required amount of product (as per Directions for Use Table) to the tank using only the measuring device provided.
3. Add the remainder of the water.
4. Always maintain agitation to keep the product in suspension. If the spray solution is allowed to stand, thoroughly re-agitate before using. If tank mixing with another product, ensure AW Militia 600 WG is in suspension before adding the other product to the tank. If using in conjunction with liquid fertilisers, slurry the product in water before mixing the slurry into the liquid fertiliser. Do not add surfactants and check with the Department of Agriculture on compatibility.

Crop rotation recommendations Many crop species are sensitive to metsulfuron methyl. The minimum recropping intervals are given in the table below. DO NOT rotate crops other than those mentioned below to land previously treated with metsulfuron methyl. It is advisable to determine crop tolerance on a small scale before sowing larger areas.

• Soil pH is to be determined by laboratory analysis using the 1:5, soil: water suspension method. ** Including natural regeneration of medics and subterranean clover.

RESISTANT WEEDS WARNING GROUP B HERBICIDE

SUREFIRE METSULFURON METHYL HERBICIDE is a member of the sulfonylurea group of herbicides. The product has the inhibitor of the enzyme acetolactate synthase (ALS) mode of action. For weed resistance management the product is a Group B herbicide. Some naturally occurring weed biotypes resistant to the product and other Group B 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 this product or other Group B herbicides.

GENERAL INSTRUCTIONS - CEREAL CROPS SUREFIRE METSULFURON METHYL HERBICIDE is a selective herbicide which can be used in cereal crops at the early post emergence stage of the crop (3 leaf to before booting stage). It may also be applied early in the crop for the control of weeds. Best results are obtained if weeds are small (no larger than 5cm in height or diameter) and actively growing. To achieve good weed control it is preferable that rainfall wets the soil to a depth of 5 to 7.5 cm within 4 weeks of application. If application is not made when conditions and weed growth are optimum, results may be slow to appear and some weeds may only be suppressed or stunted. For post emergent application, the product will remain in the soil for a period of time. The soil persistence will depend on environmental conditions such as soil pH, moisture, temperature and soil organic matter. Breakdown is faster in warm, wet acid soils and slowest in alkaline, cold, dry soils. This product does NOT provide acceptable residual control.

Crop Safety • Do not apply to the wheat varieties Miling, Jacup, King or Harrier • Do not apply to crops undersown with legumes, as legumes will be seriously affected by the product. • Should the crop have been treated with another sulfonylurea herbicide e.g. chlorsulfuron, consult your local representative or Department of Agriculture before application of SUREFIRE METSULFURON METHYL HERBICIDE as crop injury may occur. • Do not apply to crops that are stressed by any factor such as adverse environmental conditions, waterlogging, drought, frost, poor nutrient status, extreme acid or alkaline soil conditions, insect or nematode damage. Crop injury may occur if the product is applied to these crops. If the crop is stressed after application of the herbicide, temporary and slow growth may occur but the final yield is normally unaffected as the crop will recover. Application to soils with pH 5.5 or less may result in some crop retardation, especially if the crop is stressed.

Application Equipment For control of weeds in winter cereal crops the product may be applied by ground or air. Ground spraying Ensure the boom is properly calibrated to a constant speed or rate of delivery for thorough coverage and uniform spray pattern. Avoid overlapping and shut off boom while starting, turning, slowing or stopping as injury to the crop may occur. Apply in a minimum of 50L prepared spray/ha. Aerial spraying Apply in a minimum of 20 L/ha. Application in higher water volumes may improve weed control reliability. Direct spraying in conditions which favour drift can cause damage to susceptible crops, or in winds likely to cause drift onto sensitive crops or fallow areas to be planted to sensitive crops. Turn off boom when downwind, near trees, water or waterways. The use of Micronair equipment is not recommended as the fine droplets emitted may lead to spray drift. NOTE: DO NOT apply tank mixes with diuron by aerial application.

Add of Surfactant/Wetting Agent Always add a non-ionic surfactant/wetting agent at the rate of 0.1% (active constituent) of final spray volume. The use of spraying oils is NOT recommended. NOTE: DO NOT add a surfactant/wetting agent when tank mixing with terbutryn or diuron.

TANK MIXES WITH DIURON Read and follow all label directions including restraints, spray drift restraints, mandatory no-spray zones, critical comments, withholding periods, regional use restraints and safety directions for the tank mix products.

Compatibility SUREFIRE METSULFURON METHYL HERBICIDE is compatible with most commonly used broadleaf herbicides including: 2,4-D Amine, bromoxynil/MCPA, clopyralid (500 g/L), diflufenican/MCPA ester, LVE MCPA, LVE MCPA amine, MCPA/picloram K salts, terbutryn, terbutryn/ MCPA K salt, broadstrike, dicamba, diuron flowable, Eclipse, fluroxypyr, glyphosate, Jaguar, Lontrel, metribuzin. The product is also compatible with commonly used insecticides such as chlorpyrifos and Omethoate. Some temporary crop yellowing may occur with these mixtures. Other mixtures should be tested on a small scale before large areas are treated. NOTE: The compatibility of SUREFIRE METSULFURON METHYL HERBICIDE with grass herbicides varies between products and weed species (refer table below). DO NOT mix with Mataven¹.

GENERAL INSTRUCTIONS BRUSH APPLICATIONS, ESTABLISHED PASTURES AND PASTURE RENOVATION

SUREFIRE METSULFURON METHYL HERBICIDE is a selective herbicide which is rapidly absorbed by roots and leaves. • Always add a surfactant/wetting agent. • Best results are achieved when: o Application is made to actively growing plants which are not stressed by any factors such as dry weather conditions, waterlogging etc. Application to weeds that are not actively growing due to adverse conditions may result in weeds only being stunted or suppressed. o Plants to be treated must be thoroughly covered. This is essential to achieve maximum herbicide uptake • Regrowth may occur if the product is applied when plants are stressed or if complete spray coverage is not achieved. If regrowth does occur, re-treatment at the rates recommended on this label is recommended. For blackberries re-treatment should only be undertaken if plants are at least 1 m tall. This may not be until 2 years after the initial application. • Legumes will be removed from pasture if oversprayed with SUREFIRE METSULFURON METHYL HERBICIDE. • If weeds have been previously sprayed with other herbicides or if the weeds have been burned or slashed ensure if green regrowth appears treating with SUREFIRE METSULFURON METHYL HERBICIDE. • It is recommended that this product not be applied to bushed bearing mature blackberries due to the collection of bleached ripe for food purposes. • Introduced grass species may be severely damaged if oversprayed. • Legumes are extremely sensitive to SUREFIRE METSULFURON METHYL HERBICIDE and will be removed from the pasture if over sprayed. • Some grasses will be damaged in pasture sprayed with this product and biomass reduction may be reduced for limited months. • Some temporary yellowing and some stunting may occur when used on perennial phalaris and established perennial cocksfoot. • ALL grasses and legumes can be damaged and or removed by a SUREFIRE METSULFURON METHYL HERBICIDE/Glyphosate mixture. • The following weeds will be controlled: barley grass (Hordeum leporinum), brome grass (Bromus unioloides), Silvergrass (Vulpia spp.), winter grass (Poa annua). • Best results will be achieved if weeds are allowed to recover from grazing prior to herbicide application to allow for adequate uptake of the product. Sorrel and docks particularly require new leaf growth.

INSTRUCTIONS SPECIFIC TO ESTABLISHED PASTURES AND PASTURE RENOVATION • Some sorrel seedlings may germinate after the break in the following year. • Ungerminated clover will not be affected but seed set in the year following application will be significantly reduced. • If oversprayed the damage it may be necessary to re-sow clover. • For Pasture Topping situations this product may be mixed with glyphosate but ensure crop rotation recommendations are observed. Refer to the directions for use for each target weed on each product label.

Spray Preparation SUREFIRE METSULFURON METHYL HERBICIDE is a dry flowable granule which must be mixed with clean water. Always add a wetting agent/surfactant. (See "Use of surfactant/wetting agent" below)

1. Partially fill the spray tank with water.
2. With the agitation system engaged, add the required amount of product (as per the Directions for Use table) to the tank using only the measuring device provided.
3. Add the remainder of the water.
4. Always maintain agitation to keep the product in suspension. If the spray solution is allowed to stand, thoroughly re-agitate before using. If tank mixing with another product, ensure SUREFIRE METSULFURON METHYL HERBICIDE is in suspension before adding the other product to the tank. If using in conjunction with liquid fertilisers, slurry the product in water before mixing the slurry into the liquid fertiliser. Do not add surfactants and check with the Department of Agriculture on compatibility.

Use of Surfactant/Wetting Agent The use of a SUREFIRE METSULFURON METHYL HERBICIDE alone - it is important that a surfactant/wetting agent is ALWAYS used with this product. If no specific wetting agent/surfactant is recommended in the Directions for Use table, use a non-ionic surfactant (100%) at 100 mL/100L of final spray volume.

---

• 14 - - 11 -

SUREFIRE METSULFURON METHYL HERBICIDE tank mix with glyphosate - Use a non-ionic surfactant when mixing with glyphosate. In some tank mix situations the use of an organosilicone penetrant (eg PCT REACTOR) is recommended. This recommendation must be strictly followed in order to achieve adequate weed control.

Gas Gun Applications - An organosilicone penetrant (eg PCT REACTOR) should be added at the rate of 10 mL/5L or 200 mL/100 L of final spray volume. Where a mineral spray oil is recommended use 1L/100L of final spray volume (ie 1% volume/volume). A non-ionic surfactant should still be used with this mixture. Always read the instructions on the companion product label when tank mixing.

Application Equipment SUREFIRE METSULFURON METHYL HERBICIDE may be applied by air, hand gun, boom spray or gas gun according to the Directions for Use table. Hand Gun - Ensure complete and uniform coverage of all canes and foliage. Pressures of 550-750 kPa (80-100 psi) are recommended depending on the type of nozzles and target plants. As an example: Use No.4 or 5 spray nozzle for individual bushes or broadleaf weeds less than 1m high. Use No. 6 or 5 spray nozzle for bushes 1-2m high and No. 7 or 8 spray nozzle for large bushes 2-3m high or for bushes with a large diameter. When using 3g SUREFIRE METSULFURON METHYL HERBICIDE + 400 mL of Surefire Glyphosate 360 Herbicide application of greater than 400 L/ha of water may assist penetration. NOTE: For blackberry regrowth use the large spray nozzle/high water volume with as wide a cone setting as possible. Use even, side by side spray pattern moving from the base of the top of the bush. For blackberries it is important that runners at the side and top of the bush are treated and that spray penetrates larger bushes to the wet foliage of canes.

Boom Spray - Ensure the boom is properly calibrated to a constant speed or rate of delivery for thorough coverage and uniform spray pattern. Flat fan-type spray pressures of 280 to 280 kPa are recommended. Adjust the boom height to ensure correct spray overlap. Apply in a minimum of 150L prepared spray/ha. Increase to 200L/ha or more for dense stands.

Gas Gun - Ensure thorough coverage. The use of a suitable dye is recommended to allow the operator to see which plants have been treated.

Aerial Application (Helicopter only) - Use a properly calibrated helicopter using the half overlap opposite pass techniques. Apply in a minimum of 100L/ha on blackberries or 60L per ha on Mimosa pigra and up to a maximum of 200L prepared spray per hectare. Use a VMD of 300 microns. High temperatures and/or low humidity may cause excessive evaporation of droplets and may reduce results. Where bushes are large and or terrain is steep higher water volumes are necessary to ensure adequate coverage. Avoid spraying in conditions which favour temperature inversions or in still conditions. Turn off spray booms whilst passing over creeks, dams or waterways. Avoid spraying where drift can move onto crop areas that are likely to be planted to crops and non target pastures as injury may occur. Do not apply when wind gusts are exceed 10-15 km/hour or in conditions (e.g. pigra).

Tank Mixtures with Surefire Glyphosate 360 Herbicide: In certain situations such as the presence of harder to kill species or in follow-up treatment situations a tank mix with Surefire Glyphosate 360 Herbicide may provide improved weed control (see Directions for Use table).

Compatibility This product is compatible with glyphosate formulations and commonly used pasture herbicides such as MCPA Amine, MCPA Ester, 2,4-D Amine, dicamba, Clopyralid 300, Fluroxypyr 200, and commonly used insecticides such as chlorpyrifos and omethoate. Always refer to the companion product label for instructions/ restraints.

CROP ROTATION RECOMMENDATIONS Many crop species are sensitive to metsulfuron methyl. The product is broken down in the soil mainly by chemical hydrolysis and to a lesser degree by soil microbes. Other factors which affect breakdown are soil pH, soil moisture and temperature. Breakdown is faster in warm, wet acid soils and slowest in alkaline, cold, dry soils.

Legumes will be removed from pasture if they are over sprayed with the product.

Other species which are sensitive to metsulfuron methyl are: Canola, Canola, Cereal Rye, Chickpeas, Faba Beans, Japanese Millet, Linseed, Lupins, Lucerne, Maize, Medics, Panorama Millet, Peas, Safflower, sorghum, soybeans, sub clover, sunflower, triticale, white, wheat French millet.

The area sprayed with SUREFIRE METSULFURON METHYL HERBICIDE may be replanted to the specified pasture species after the interval in the following table.

(a) Sub Clover varieties: Junee, Karridale, Seaton Park, Trikkala (b) Tolerance of species should be determined on a small scale before sowing commercial areas

• Soil pH is to be determined by laboratory analysis using the 1:5, soil: water suspension method.

For rates higher than 15g/ha the following applies: • For soils with pH less than 6.5, a bioassay should be conducted at least 1-2 months before over-sowing the treated areas with grasses or legumes. It is suggested that small areas be oversown 1-2 months prior to the planned time for sowing to check for possible harmful residual. • For soils with pH greater than 7 DO NOT replant until a company representative has been contacted.

APPLICATION IN WINTER CEREAL CROPS DIRECTIONS FOR USE: RESTRAINTS: DO NOT apply to crops under stress. DO NOT apply if rainfall is expected within 2 hours. DO NOT store the prepared spray for more than 2 days. DO NOT treat weeds that are under stress. DO NOT apply to crops before the three leaf stage when used post emergent. DO NOT use on flood or furrow irrigated crops.
