General Instructions

Uses

Ospray Diquat 200 Herbicide is an aqueous solution of diquat, a non-volatile herbicide with unique properties. It very quickly kills green growth with which it comes into contact and is particularly effective against broadleaved weeds. It is inactivated on contact with the soil and crop roots and seeds below the soil remain unharmed. It can be safely applied around bushes and trees which have no green bark. It is non-volatile, easily mixed with water and active at low concentrations.

Resistant Weeds Warning

Ospray Diquat 200 Herbicide is a member of the bipyridl group of herbicides. The product has the inhibitor of photsynthesis at photosystem I mode of action. For weed resistance management, the product is a Group L herbicide.

Some naturally-occurring weed biotypes resistant to the product and other inhibitors of Group L 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 inhibitors of Group L 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 this product to control resistant weeds.

Mixing

Add the required quantity of Ospray Diquat 200 Herbicide to water in the spray tank and agitate to give even mixing. Agitate again if left standing. Use clean water only, as suspended soil particles in dirty water will interfere with herbicidal action.

WETTING AGENT

Ospray Diquat 200 Herbicide contains no wetting agent and a non-ionic wetting agent must be added to the spray mixture unless otherwise specified. Add Agral at the rate of 200 mL/100 L or Wetter 1000 at 160 mL/100 L of prepared spray unless otherwise specified.

Application

For best results, an even and complete coverage and good penetration of the spray into the target foliage is necessary. Best results will be obtained when application is made in dull weather or at the end of the day. Ospray Diquat 200 is rapidly absorbed and is not affected by rain falling shortly after application.

Application Rates

Use the higher rates specified in the Directions for Use for dense or weedy crops. For application to seedling weeds, Ospray Diquat 200 Herbicide is generally recommended at 1.4L/ha and Paraquat 250 Herbicide at 1.2L/ha. Use Ospray Diquat 200 Herbicide at 2.8 to 4L/ha and Paraquat 250 Herbicide at 1.6 to 3.2L/ha when weeds are at the older stages of growth. Paraquat 250 Herbicide is preferred where grasses are dominant and Ospray Diquat 200 Herbicide where there are mainly broadleaf weeds.

Boom Spraying

A boom sprayer fitted with flat fan nozzles is preferred to ensure even coverage and to minimise drift. The boom should be set at sufficient height above the crop to provide a complete double overlap of the flat spray pattern. Spray drop arms on booms are useful for dense crops such as potatoses. A minimum  spray volume of 100L/ha is recommended. Aim for a spray quality in the fine to medium range, ie a VMD droplet size of 200 to 250 µm. Generally a flat fan nozzle operated at 200 to 300 kPa is preferred.

High Volume Spot Spraying

Hand-held equipment use 250ml of product per 100 L of water and spray to visible wetness (about 700 to 1000L/ha). Use 50ml product plus 30ml Agral per 15 litre knapsack.

Aerial Application

Flying height, pressure, nozzle size and positioning on the aircraft should be such as to minimise spray drift. Apply 30 to 60 L of spray per hectare. Avoid spraying in high winds or under temperature inversion conditions. Wash any spillage during filling of the aircraft and make sure there are no leaks in the spraying system. Inspect the aircraft regularly for signs of corrosion and ensure the paintwork is in good condition.

Caution - Use By Aircraft

Although this product is no different in drift behaviour from other chemicals, it has a rapid spotting effect on green foliage and, as with all herbicides; special care must be taken to avoid drift onto adjacent crops. Aircraft operators must not apply during periods of thermal (temperature) instability, and should avoid wind conditions and flying heights conducive to drift.

Weed Control In Row Crops, Vegetables And Market Gardens

Pre-planting and pre-crop emergence:

To control weeds in seed beds before sowing, or post-sowing seed crop emergence, apply as a blanket spray with this product using boom spray equipment or knapsack sprayers.

Post-emergence inter-row weed control:

Use shielded nozzles for rapid control of weeds in inter-row spaces of row crops, after crop seedlings have emerged, or when transplanted crops are established. Direct the spray so that it does not touch the crop.

Pre-harvest crop desiccation:

Green crop foliage and weeds can seriously interfere with harvesting operations of a number of crops.  This product can be used to facilitate harvesting by desiccating weeds, accelerating the drying of crops and reducing the moisture content of seeds. Drying costs are reduced, harvesting delays and associated risks are avoided.

WARNING

Markers - If possible, fixed markers should be used. Human markers are not recommended unless flaggers are protected by engineering controls such as vehicles with cabs.

Compatibility

This product mixes readily with Paraquat 250 Herbicide, the soil residual herbicides Atrazine granules, Diuron WG, Simazine Granules and other 200 g/L Paraquat products, where prolonged weed control is required as well as a quick knockdown.

Restraints

DO NOT apply with misting machines or CDA applicators.

DO NOT spray when weeds are under drought stress or when covered with dust or soil.

Grazing: DO NOT GRAZE OR CUT SPRAYED VEGETATION FOR STOCK FOOD FOR 1 DAY AFTER APPLICATION.

Harvest:

Cotton, dry beans, mung beans, asparagus, hops, orchards and vineyards, row crops, vegetables and market gardens, oats, wheat and winter cereals: - NOT REQUIRED WHEN USED AS DIRECTED

Lentils, chickpeas and faba beans - DO NOT HARVEST FOR 2 DAYS AFTER APPLICATION

Pigeon peas, canola,sunflowers, soybeans, sugarcane - DO NOT HARVEST FOR 4 DAYS AFTER APPLICATION

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.
