General Instructions

Directions for Use

BEFORE using Fumaphos you should consider the following: Timing of treatment - If it will be necessary to move grain/commodity before the Total Fumigation Period has expired, then fumigation should NOT be commenced. Movement of treated commodities or empty containers during application, fumigation exposure or ventilation risks exposure of transport and handling workers and the public to harmful levels of phosphine and is contrary to label instruction. The Total Fumigation Period is the sum of the time required for Exposure to phosphine and the time needed to ventilate the grain. A shortened Exposure Period will not be effective for storage pest control and a reduced Ventilation Period poses a serious risk of phosphine gas poisoning to workers and bystanders. In addition a Withholding Period of two days is required after completion of ventilation before the grain is allowed to be used for human consumption or for animal feed. See Notes 4 & 5 for a detailed description of the Minimum Exposure Period and the Ventilat ion Period. Safety and handling of Phosphine Products - Phosphine is a highly dangerous fumigant and fumigation should only be undertaken in situations where the safety of workers and the public can be ensured. Observe all RESTRAINTS, PRECAUTIONS and instructions on the label.

Notes

NOTES: 1) FUMIGATION WILL CONTROL ALL STAGES OF INSECTS ONLY IN STRUCTURES/ENCLOSURES THAT ARE WELL SEALED*. Wel l sealed structures/enclosures are fumigation chambers, well sealed silos, sheds and buildings, and other fumigation enclosures made gas-tight with gas-proof sheeting. Well sealed means permanent sealing of porous surfaces, seams and cracks and temporary sealing of intake and/or outlet valves, doors, fan housings, windows and hatches. For further information, see appropriate industry advisory documents such as Grains Research and Development Corporation 'Advice' sheet '$ealed $ilos $ave', available from State Departments of Agriculture or Primary Industries. Increasing the application rate will not compensate for gas lost from an unsealed enclosure.

NOTE: STRUCTURES MUST BE WELL SEALED. IF THEY ARE NOT, FUMIGATION WILL NOT GIVE ADEQUATE C ONTROL, AND WOULD BE CONTRARY TO LABEL DIRECTIONS.

2) STORAGE PESTS include: lesser grain borer, cadelle, cigarette beetle, confused flour beetle, dried fruit beetle, flat grain beetle, merchant grain beetle, red-legged ham beetle, rustred flour beetle, saw-toothed grain beetle, skin and hide beetle, spider beetles, warehouse beetle, Angoumois grain moth, Indian meal moth, Mediterranean flour moth, mottled grain moth, raisin moth, tobacco moth, tropical warehouse moth, psocids, stored products mites, bean weevil, coffee bean weevil, granary weevil, maize weevil, pea weevil and rice weevil. Approved treatment dosages will also kill any cockroaches, rats and mice present.

3) PHOSPHINE APPLICATION RATES are based on the internal volume of the structures to be fumigated; they apply equally to full or partly filled or empty structures and they apply to all commodities. The commodity equivalent rates (g/tonne) should only be used when the commodity stowage factor is known; they apply only when the storage structures are full or nearly full or when part-filled structures are dosed on the tonnage equivalents of their internal volumes. The calculated commodity equivalent dosage must be based on the rate per volume. The application rate of 1.5 g phosphine per 1 metre3 is equivalent to: Capacity of fumigation enclosure/ Number tablets

tonnes wheat/bushels/cubic metres

20 /730 /27 /40(120g)

50 /1830 /65 /100(300g)

100 /3660 /130 /200(600g)

300 /11000 /375 /600(1800g)

4) MINIMUM EXPOSURE PERIODS are needed to allow products to react to completion and to expose insects for long enough to kill all stages. A SHORTENED EXPOSURE PERIOD CANNOT BE COMPENSATED FOR BY INCREASED DOSAGE. Insect death and reaction of the tablets are both slower at lower temperatures. Temperatures specified are those within the commodity to be fumigated. The minimum exposure period should start from time of completion of application of product.

5) VENTILATION PERIOD - ON COMPLETION OF EXPOSURE PERIOD:

Ventilation of structures is complete only when phosphine concentrations measured at appropriate locations in the enclosure and work area are below the Threshold Limit Value - Time Weighted Average (TLV-TWA) exposure standard of 0.3 ppm. The following are minimum ventilation periods required and may need to be increased to ensure the exposure standard is not exceeded.

Minimum Ventilat ion Periods:

Structures, including bunker storages, containing treated commodities:

a) Without through flow (i.e. access only through the headspace): not less than 5 days

b) With through flow and natural draught (wind): For structures of 300 tonnes or greater capacity: 2 to 5 days depending on size. For structures of less than 300 tonnes capacity: 2 days

c) With through flow and forced draught (flash-proof fan) operated 2 hours on and 2 hours off: not less than 1 day.

Tobacco: In bales: not less than two days. In cases and hogsheads: not less than 3 days.

Empty Buildings and Enclosures:

a) Without through flow: 5 days

b) With through flow and natural draught (wind): For structures of 300 tonnes or greater capacity: not less than 2 days, depending on structure size, openings and prevailing wind speed. For structures of less than 300 tonnes capacity: 2 days.

c) With through flow and forced draught (flash-proof fan) operated 2 hours on and 2 hours off: 1 to 2 days depending on size of structure.

Fumaphos releases phosphine gas when exposed to air. Phosphine penetrates throughout the commodity to kill eggs, larvae, pupae and adult stages of storage pests in sealed enclosures, but some eggs, pupae and adults will survive in unsealed enclosures (see Note 1 above). Protect by sealing or otherwise, sensitive electrical and electronic equipment (computers, meters, switches, fire alarm systems, etc.) containing copper/copper alloy components, photographic film or copy paper. Phosphine corrodes copper based materials.

Application

Fumigation of Commodities in Silos and Bulk Storages: Place the tablets in a single layer and separated from the commodity e.g. on non-flammable trays/sheets which are evenly spread on the commodity surface inside the storage.

Fumigation of Commodities under Gas Proof Sheeting: Place tablets spaced from each other on non-flammable sheets/trays evenly distributed between and/or alongside stacked commodities in a manner that allows free circulation of gas. Ensure that the sheeting is sealed in a gas-tight manner after application.

Fumigation of empty storages/enclosures: Place tablets spaced from each other on nonflammable sheets/trays evenly spread in the enclosure; with application starting at the furthest point from the exit door. Ensure the enclosure is made gas-tight. Lock and seal exit door after application.

Insecticide Resistance Warning

For insecticide resistance management Fumaphos is a group 8B insecticide. Some naturally occurring insect biotypes resistant to Fumaphos and other Group 8B insecticides may exist through normal genetic variability in any insect population. The resistant individuals can eventually dominate the insect population if Fumaphos or other Group 8B insecticides are used repeatedly. The effectiveness of Fumaphos on resistant individuals could be significantly reduced. Since occurrence of resistant individuals is difficult to detect prior to use, National Fumigants Pty Ltd accepts no liability for any losses that may result from the failure of Fumaphos to control resistant insects. Application of Fumaphos in unsealed storages/ enclosures and use of low dose rates and shortened exposure periods is contrary to label instruction and will contribute to development of resistance.

Restraints

DO NOT fumigate in inhabited buildings.

DO NOT fumigate in work situations where there is a risk that phosphine gas could leak from fumigation enclosures into working areas.

DO NOT use on commodities, or in empty containers, railcars or vessels that are in transit or likely to be in transit during the Exposure and/or Ventilation Periods.

DO NOT use in road transport vehicles (including a truck or road hauled container).

DO NOT heap tablets. Heaped tablets limit gas release.

DO NOT add water to the tablets.

DO NOT use when the commodity temperature is less than 15C or the relative humidity within the structure is less than 25% or, with raw cereal grains, the moisture content is less than 9%.

DO NOT apply in structures that are not well sealed.

DO NOT apply as a surface-only treatment in a structure whose height exceeds twice its width, unless the structure/enclosure has a gas recirculation device fitted.

Protection of wildlife, fish, crustaceans and environment

This product is highly toxic to wildlife. Dangerous to fish. DO NOT contaminate streams, rivers or waterways with the chemical or used containers.

Safety Directions

Very dangerous. Product releases dangerous phosphine gas slowly in moist air and immediately if wet. Can kill if inhaled or swallowed. DO NOT inhale dust or vapour. Avoid contact with eyes and skin. Open container in the open air. Keep away from water and liquids. Keep away from naked flames. Forms toxic gas. Use the entire contents in one operation; if not possible, seal container thoroughly with waterproof adhesive tape or airtight closure. Wash hands after use. When opening the container or using the product wear elbow length PVC gloves and full face piece respirator with combined dust and gas cartridge (canister) or supplied air respirator. After each days use wash gloves and respirator (if rubber wash with detergent and warm water).

Storage

Store Fumaphos in the closed, original container in a cool, dry, well ventilated locked area, out of the reach of children and unauthorised persons and away from all dwellings, animals, food, feedstuffs, seed and fertilisers. DO NOT store or carry container in vehicle cabins (this includes glove compartments, luggage compartments or other common air-spaces). Keep away from water and liquids. Water and many liquids cause immediate release of phosphine from the product. Uncontrolled release of phosphine may result in fire or explosion and release of gas will pose a serious risk of injury to workers and bystanders.

Disposal

After fumigation with the product on trays/sheets remove the spent tablets and ensure residual phosphide is destroyed before disposal, e.g. by swamping with dilute acid or soapy water in open air until bubbling ceases. Dispose of deactivated residues below 500 mm in an approved disposal pit specifically marked and set up for this purpose, clear of waterways, desirable vegetation and tree roots. Triple rinse the empty containers with soapy water to ensure residual phosphide is destroyed. Dispose of rinsings in an approved disposal pit. Destroy empty containers by breaking, crushing or puncturing them. Dispose of the containers at a local authority landfill. If no local authority landfill is available, bury the containers below 500 mm in an approved disposal pit. DO NOT burn empty containers or product.

Precautions

Precaution

Show the following warning sign prominently at all approaches to every fumigation site. "DANGER - POISON GAS - KEEP AWAY"

Keep animals, children and unauthorised persons away from the area under treatment until the area is shown to be free from phosphine as indicated by a gas measuring device.

Warning

Containers must be opened in the open air. Whilst opening containers take care and point containers away from the face and body, as under certain conditions possible buildup of gas may result in flash flame upon exposure to air. Application rates higher than label directions and contrary to label instruction could cause the gas concentrations to reach the lower flammability level which is 1.79% by volume (17,900 parts per million). When used according to the label directions, the amount of gas produced remains far below the lower flammability level.

Re-entry Period

After application, wait until the Exposure Period has passed, then thoroughly ventilate for the required Ventilation Period and to the required Standard. Reentry to fumigation areas is not recommended until measuring device(s) indicate that they are free of phosphine. The use of gas detection tubes or other measuring devices is recommended for monitoring gas levels in fumigation areas as phosphine gas may still be present even after treated commodities have been removed and fumigation areas ventilated. DO NOT re-enter a storage after application has commenced or once treated grain/commodity has been emptied without wearing a full face respirator with particulate (P1) and phosphine gas filter cartridge (canister) or self-contained breathing apparatus, until a measuring device indicates that it is free of phosphine or the Total fumigation period (minimum exposure period plus ventilation period) has elapsed.

APVMA Code :61143 Active Constituent(s): 500g/Latrazine

Registered For Commercial Use Domestic Use Overview Controls weeds and grasses in sorghum, maize, sugarcane, lupins, TT-canola and other crops. Chemical Group triazine General Instructions ATRAZINE 500 is a pre- and post-emergent herbicide which will selectively control: - weeds and grasses in sorghum, maize, sweet corn, sugar cane, lupins, broom millet, saccaline and forage sorghum - mintweed in established lucerne - Brome Grass in sirocco phalaris, demeter fescue and currie cocksfoot grass seed crops - provide control of weeds and grasses growing on a fallow in a conservation tillage system. Established perennial species are not satisfactorily controlled at the rates recommended. Duration and effectiveness of control depends on the amount of chemical applied, soil type, rainfall and particular weed species. DO NOT apply more than 6 litres per hectare per year for all crops except forestry. DO NOT apply more than 9 litres per hectare per year in forestry situations in sandy soils and soils classed as highly erodible and not more than 16 litres per hectare per year for 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 herbicides in TT-canola. The Strategy encompasses: - Integrated Weed Management; - the specifi c 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. Copies of the Strategy are available from a Ospray representative. It is advised that consultation be undertaken with an appropriate agronomist, consultant or Departmental adviser prior to the use of ATRAZINE 500 on TT-Canola. To minimize herbicide 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 (simazine 500 g/L) or (atrazine 500 g/L) plus trifl uralin pre-emergence. A follow-up with a Group A herbicide (if ryegrass is susceptible) or atrazine 500 g/L may be necessary. Broadleaf Weeds only: use atrazine 500 g/L post-emergence. - DO NOT use atrazine 500 g/L or simazine 500 g/L 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. Resistance Weed Reporting Growers should collect plant or seed samples where weeds that are normally susceptible to atrazine and simazine 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 atrazine 500 g/L or simazine 500 g/L or a combination of the two products to be applied to the crop during the growing season is 4 L/ha. On alkaline soils (pH greater than 6.5) - The maximum rate of atrazine 500 g/L or simazine 500 g/L or a combination of the two products to be applied to the crop during the growing season is 2 L/ha. Post-emergence use - It is recommended that atrazine 500 g/L only be used, and at rates of 2 L/ha or less, on both acid or alkaline soils. Mixing Settling may occur after storage for some weeks. Stir product or invert container several times before opening. Pour the product into the spray vat through a strainer to remove any dry particles or fl akes, which can occasionally occur under hot storage conditions. Add the full quantity of ATRAZINE 500 to the partly fi lled spray tank while agitating. Fill tank and agitate to ensure thorough mixing. Continue agitation while spraying. Agitate vigorously from the bottom if allowed to stand. Reseal partly used container immediately. DO NOT mix or load this product within 20 m of any well, sink or hole or intermittent perennial, stream or river. Application Ground application: application can be made as an overall or band treatment. Minimum band width should be 30 cm. Apply 50 to 100 litres total spray volume per hectare. Aircraft application: with aircraft application the need for good soil moisture at the time of application and follow up rain or irrigation within 10 days is most critical. Apply 20 to 30 litres total spray volume per hectare. DO NOT use human flaggers when applying by aircraft, unless protected by engineering controls such as enclosed cabs. TT-Canola: DO NOT apply to TT-canola by aircraft. Apply only with a low boom sprayer with a 60 m buffer zone downwind of treated fi elds to natural or impounded lakes or dams, and a 20 m 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. Timing TIME OF APPLICATION (sorghum, maize, broom millet, saccaline, sweet corn) Pre-plant or pre-emergence applications are preferred where grasses are the major problem. (a) Pre-plant application - followed by post-emergence application. Apply after establishment of the seedbed and up to two weeks prior to sowing. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist. If using this technique on irrigated crops then a post-emergence spray must be applied as soon as possible after the crop has emerged and has developed 2 to 3 leaves. (b) At sowing application - followed by a post-emergence application. Apply at or immediately after planting and before crop and weeds emerge. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist. If using this technique on irrigated crops then a post-emergence spray must be applied as soon as possible after the crop has emerged and has developed 2 to 3 leaves. (c) At sowing application. Apply at or immediately after planting and before crop and weeds emerge. Application should preferably be made to moist soil and rain or irrigation should follow application. Mechanical incorporation may also assist. Note: applying the total amount as a pre-emergent application increases the risk of crop damage. (d) Post-emergence application Application must be made to seedling broadleaf weeds and grasses when they are not more than 1 cm high. Normally the crop is then at the 2 to 3 leaf stage. For best results the soil should be moist and rain or irrigation should follow application. Add a non-ionic surfactant (100 %) at a rate of 135 mL per 100 L of spray solution, for all post- emergent applications in sorghum, broom millet and saccaline, and 5.5 L/ha of crop oil for maize and sweet corn. See Warning above. Incorporation: If applied to dry soil harrow to incorporate the product into the soil not more than 4 cm deep. Note: should weeds develop after a pre-plant or pre-emergence application a shallow cultivation may assist. Avoid deep cultivation which may throw untreated soil over the sprayed area, as this may seriously reduce weed control. Compatibility Compatible with glyphosate, atrazine, ametryn, diuron, Primatol† Z, dicamba, diquat/paraquat mixtures, hexazinone. In sugar cane only the addition of sodium 2,4-D will assist in short term suppression of Nutgrass and other sedges. Restraints DO NOT plant crops other than those recommended on this label for at least 6 months following treatments of this product at rates of up to 2.5 litres per hectare and for 18 months following treatments of 2.5 to 6.0 litres per hectare. DO NOT apply to waterlogged soil. DO NOT apply if heavy rains or storms that are likely to cause run-off are forecast within two days of application. DO NOT irrigate to the point of run-off for at least two days after application. 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. DO NOT use a knapsack sprayer for application in eucalypts and Pinus radiata plantations. DO NOT use or apply this product post-emergence in triazine tolerant (TT) Canola on raised beds or where furrows have been created in soil for the purposes of holding or channeling water. DO NOT apply product to any drainage line. Drainage lines show evidence of the action of periodically fl owing water (for example, gravel, pebble, rock and sand bed, scour hole or nick point) and/or an incised channel at least 30 cm deep. DO NOT handle, mix, apply or conduct testing operations in areas susceptible to run-off where drainage results in rapid entry into waterways, particularly where no specifi c and effective action has been taken to prevent run-off into waterways. These areas may include areas mounded perpendicular to the contour, roads, access tracks, snig tracks, and compacted log dumps. Resistance Warning Ospray ATRAZINE 500 Flowable Herbicide is a member of the triazine group of herbicides and has the inhibitors of photosynthesis at photosystem II mode of action. For weed resistance management, this product is a Group C herbicide. Some naturally occurring weed biotypes resistant to ATRAZINE 500 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 ATRAZINE 500 or other Group C herbicides. Since the occurrence of resistant weeds is diffi cult to detect prior to use, Ospray Pty. Ltd. accepts no liability for any losses that may result from the failure of ATRAZINE 500 to control the resistant weeds. Advice as to strategies and alternative treatments that can be used should be obtained from your local supplier, consultant, local Department of Agriculture, Primary Industries Department or a Ospray representative. Any incidents of resistance must be reported to Ospray Pty. Ltd. Protection of wildlife, fish, crustaceans and environment DO NOT contaminate streams, rivers or waterways with the chemical or used containers. This product is very highly toxic to algae and aquatic macrophytes. DO NOT apply this product within 60 m of natural or impounded lakes or dams. DO NOT use in channels or drains. DO NOT apply under meteorological conditions or from spraying equipment which could be expected to cause drift of this product or spray mix into adjacent areas, particularly wetlands, water bodies or watercourses. Protection of crop, native and other non-target plants DO NOT apply under weather conditions or from spraying equipment which may cause spray to drift onto nearby susceptible plants/crops, cropping lands or pastures. DO NOT apply or drain or fl ush 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 plant crops other than those recommended on this label for at least 6 months following treatments at rates up to 2.5 litres per hectare and for 18 months following treatments of 2.5 to 6.0 litres per hectare. DO NOT use in channels or drains. DO NOT spray foliage of desirable plants. DO NOT apply high rates of application to heavier soils if roots of desirable shrubs and trees are near the surface. DO NOT use near newly planted shrubs, young ornamentals or species with shallow roots. DO NOT plant crops other than those recommended on this label for at least 6 months following treatments at rates up to 2.5 litres per hectare and for 18 months following treatments of 2.5 to 6.0 litres per hectare. Safety Directions Avoid contact with skin and eyes. DO NOT inhale spray mist. When preparing spray and using the prepared spray wear elbow-length PVC gloves. After use and before eating, drinking or smoking wash hands, arms and face thoroughly with soap and water. After each days use wash gloves. 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 (contact drumMuster Collection agency or Local Council for collection sites). If not recycling, break, crush, or puncture and bury empty containers in a local authority landfi ll. If no landfi ll is available, bury the containers below 500 mm in a disposal pit specifi cally marked and set up for this purpose clear of waterways, desirable vegetation and tree roots. Empty containers and product should not be burnt. For refi llable containers, empty contents fully into application equipment. Close all valves and return to point of supply for refill or storage. Precautions Warning Sorghum, broom millet, saccaline Heavy rain immediately after application may result in excessive concentrations of herbicide 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 3.6 L/ha. To avoid the likelihood of herbicide injury use techniques (a), (b) or (d) in the Time of application section. 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 fl at 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 a rate of 5.5 L/ha 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 135 mL of 100% non-ionic surfactant per 100 L of spray mixture. Summer crops Heavy rains immediately following an application tend to result in excessive concentrations of herbicide in the seed furrow, thus encouraging possible crop injury. This is most likely to occur when a pre-plant or pre-emergence application is made using rates in excess of 3.6 litres per hectare. To avoid the likelihood of herbicide injury follow Time of Application (a), (b) or (d) listed below. Re-entry Period DO NOT enter treated areas without protective clothing until spray has dried.
