General Instructions

 

Ospray Spray-Out 250 Herbicide quickly kills a wide range of annual grasses, broadleaf weeds and some perennial grasses when sprayed directly onto the leaves. The active ingredients are rapidly and tightly absorbed by clay and silt particles in the soil and DO NOT leave any effective soil residues. Thus crops sown almost immediately after spraying are not affected by the chemicals, nor are weed seeds which germinate after spraying.

 

Where insect pests are anticipated use recommended insecticide treatment. Regular checks should be made before and after sowing.

 

Suitable residual herbicides can be tank mixed with Ospray Spray-Out 250 to provide extended in-crop weed control in fallows and subsequent cops. Read label recommendations of the respective residual herbicides prior to their use, and observe precautions against use of residual herbicides before planting susceptible cops. See compatibility statement on this label for compatibility of Ospray Spray-Out 250 with other herbicides.

 

Mixing

 

The recommended rate of Ospray Spray-Out 250 should be added to water in the spray tank and agitated to give even mixing. Agitate again if left standing.

 

Water Volume

It is essential to obtain good leaf coverage with the spray and the following volumes are recommended (see label))

 

Note:

(1) If the volume is increased above 100 L/ha additional wetter should be added at the rate of 200 mL of Agral/ 100 L or 120 mL BS1000 per 100L of additional water.

(2) Water should be clean and free from clay, silt and algae. Providing it meets with requirement, saline water, water collected from roofs, bore water, dam water and water from creeks may be used.

 

Application

 

(1) Boomspray Use only through a properly calibrated boomspray which should be fi tted with fl at fan jets and adjusted to a height to give at least double overlap of the pray at the top of the weeds being sprayed. Spraying pressures should be in the range of 240 to 280 kPa. Speed of travel should be in the range of 6 to 10 km/hr. It is essential that a good marking system be used. If a disc marker is used it must be mounted so as to turn the soil back on to the area sprayed.

 

Direct Drilling Procedure (1)

Use of Ospray Spray-Out 250 in crop establishment with no working before sowing.

 

Step Critical Comments

  1. Burn If possible crop stubble or pasture trash should be burnt early to avoid problems at sowing. Can also promote weed seed germination.
  2. Shallow cultivation - optional

    Should be carried out on opening rains to a depth of no more than 2 cm. This will encourage early even germination of weeds particularly annual grasses.
  3. Heavily graze paddocks continuously from germination

    This prepares the paddock for spraying by keeping the pasture short and open and at the same time restricts the development of the weed roots which will assist seed bed formation.
  4. Remove stock 2 to 3 days before spraying

    Allow the weeds to freshen up - important for maximum uptake of Ospray Spray-Out 250. Spraying can, however, take place immediately after stock removal provided there is suffi cient leaf cover and the pasture is not dusty.
  5. Spraying with a boom spray Accurate application and full spray cover are essential to give weed control. Note limitations as outlined under Directions for Use.
  6. Sow 3 to 5 days after spraying A rigid tyne spring release combine is preferred to ensure adequate penetration. Points should not be worn. The combine must be level and set to work 3 to 5 cm and sow seed at recommended depth. Use standard seed and fertiliser rates. When harrowing is considered necessary use trailing harrows. Sowing can commence one hour after spraying and should be completed within 7 days. Where heavy weed growth is present a better seed bed will result if sowing is delayed for 3 to 5 days.

 

Direct Drilling (Sod Seeding) Procedure - Rice (2)

 

Step Critical Comments

  1. Graze pasture heavily Allow pasture to green up before spraying, generally about 1 week. Watering may be required. When rice follows a cereal crop, the stubbles should be burnt well in advance of the anticipated date of sowing to allow weeds to germinate prior to spraying.
  2. Spray the paddock before or after direct drilling - Use 1.6 to 3.2L Ospray Spray-Out 250 per hectare. Use 1.7 to 2.2 L/ha for weeds, particularly Barnyard Grass, on rice stubbles after burning. Use 2.2 L/ha for well grazed pastures plus 500 mL Banvel 300/ha as a tank mix for clover dominant pastures. Up to 3.2 L/ha may be required where the pasture has not been properly managed prior to spraying. Use approximately 100L clean water/ha per cm growth.
  3. Direct drill rice Drill at 2 to 3 cm depth within a few hours of spraying. Do not delay for more than a few days after spraying. Spraying may be carried out after drilling.

Crop Establishment

Crop Establishment with a Cultivation AFTER Spraying. Crop Establishment Procedure (3)

 

Step Critical Comments

  1. Graze paddocks continuously from germination This prepares the paddock for spraying by keeping the pasture short and open and at the same time restricts the development of the weed roots, which will assist seed bed formation.
  2. Remove stock 2 to 3 days before spraying. Allows the weeds to freshen up - important for maximum uptake of Ospray Spray-Out 250. Spraying can take place immediately after stock removal provided there is suffi cient leaf cover and the pasture is not dusty.
  3. Spray with a boom spray Accurate application and full spray cover are essential to give weed control. Note limitations as outlined under 'Directions for use'.
  4. Cultivate Between 1 hour and 7 days after spraying. When dense weed growth is present implement penetration and resulting seed bed may be improved if cultivation commences 3 to 5 days after spraying. It is not necessary to cultivate deeper than sowing depth. Use scarifi er or combine with heavy harrows.
  5. Sow at the recommended seed and fertiliser rates and depth. Crop Establishment with a Cultivation BEFORE Spraying. Crop Establishment Procedure (4)

 

Step Critical Comments

  1. Graze Graze pasture or stubble to keep growth of weeds down to a minimum following the autumn break.
  2. Cultivate 4 to 6 weeks prior to the anticipated sowing date Cultivate after autumn rains when conditions are suitable to produce a seed bed and before heavy weed growth develops. A scarifi er and heavy harrows should be used with the aim of killing existing weed growth and leaving the seed bed in a level condition. It is not necessary to cultivate deeper than the sowing depth.
  3. Wait Wait 4 to 6 weeks to allow a full germination of weeds. Graze if necessary.
  4. Remove stock 2 to 3 days before spraying Allow the weeds to freshen up - important for maximum uptake of Ospray Spray-Out 250.
  5. Spray with a boom spray Accurate application and full spray cover are essential to give weed control. Note limitations as outlined under 'Directions for Use'.
  6. Sow Between one hour and 7 days after spraying, sow crop in the normal manner. Sow at recommended seed and fertiliser rates and depth.

NOTE: Where heavy weed growth is present at spraying, a better seed bed will result if sowing is delayed for 3 to 5 days.

 

NOTE: For on the farm advice and assistance, contact your dealer or Ospray Representative.

 

General Application Information

 

CONTROL OF WEEDS AFTER CROP HARVEST AND IN CULTIVATED AND NON-CULTIVATED FALLOWS - NORTHERN NEW SOUTH WALES AND QUEENSLAND ONLY

 

Use Ospray Spray-Out 250 for weed control after cereal harvest procedure (5)

 

New Zealand Spinach, Bladder Ketmia and Milk Thistle are often present after cereal harvest. They can be controlled by the application of 1.6 to 2.4 litres/hectare of Ospray Spray-Out 250 in at least 100 litres of clean water. Use a properly calibrated boom sprayer. Ensure that the boom is set for double overlap at the top of the weed canopy. The weed species must be free from dust and actively growing. They should not be shielded from the spray by stubble or trash. The use of a straw spreader at harvest is recommended.

 

Use of Ospray Spray-Out 250 for the control of weeds during the fallow. Procedure (6)

 

Weeds must be controlled during the fallow to conserve moisture. While cultivation can eliminate weeds it also exposes the soil to moisture loss. In addition, repeated cultivations destroy soil structure, reduce organic matter and stubble cover. This leads to the formation of hard pans, soil crusts and increases the risk of erosion. Under moist soil conditions weeds are frequently transplanted and not killed, weed growth holds the soil in clods. Ospry Spray-Out 250 provides an economical and reliable alternative for fallow weed control.

 

For use in fallows to be planted to sugar cane and for weed control prior to planting sugar cane refer to the specifi c section of the label.

 

a) Seedling Weeds:

Seedling weeds should be sprayed with 1.0 to 3.2 litres/hectare Ospray Spray-Out 250 in 50 to 100 litres of clean water (see Directions for Use table). Some diffi cult to control weeds may require a second application 7 to 21 days later, or control may be assisted by a following cultivation.

 

b) Advanced weed growth:

While some advanced weeds will be controlled by a single application of Ospray Spray-Out 250 many species will require a follow-up cultivation to complete the kill. Ospray Spray-Out 250 rapidly desiccates plant material and causes weed roots to loosen their grip on the soil. The results are improved incorporation of plant material, a reduced number of large clods and a more reliable weed kill even in moist soil. Use the recommended rates of Ospray Spray-Out 250 in 100 to 200 litres of clean water.

 

Control of transplanted weeds:

Weeds transplanted by unsuccessful cultivation present an extremely diffi cult problem. If there is a risk that cultivation will result in weeds being transplanted (particularly under moist soil conditions) it is recommended that the weeds be sprayed with Ospray Spray-Out 250 prior to cultivation (see previous section). Weeds partly covered by soil and clods provide poor conditions for successful chemical weed control. The best results will be achieved by allowing the weeds to make some regrowth to provide an adequate chemical targets. Apply the highest rate of Ospray Spray-Out 250 preferable spraying in the late afternoon or early evening.

 

Use of Ospray Spray-Out 250 for the control of seedling weeds immediately before sowing. Procedure (7)

 

a) Sowing with full disturbance (full combine)

The cultivation action of the combine aids in weed kill. Use 0.8 to 2.4 litres of Ospray Spray-Out 250 depending upon weed species (see Directions for Use table). Sowing should commence within 7 days of spraying.

 

b) Sowing with minimum disturbance (row crop, no-till planters):

A higher rate of Ospray Spray-Out 250 is recommended due to the absence of cultivation. Use Ospray Spray-Out 250 at 1.0 to 3.2 litres per hectare in Southern Australia; 1.2 to 3.2 litres per hectare in Northern Australia (Qld, Nthn NSW & NT only).

Resistance Warning

 

Ospray Spray-Out 250 Herbicide is a member of the bipyridyls group of herbicides. Ospray Spray-Out has the inhibitors of photo-synthesis at photosystem I mode of action. For weed resistance management Ospray Spray-Out is a Group L herbicide. Some naturally occurring weed biotypes resistant to Ospray Spray-Out and other 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 Ospray Spray-Out or other Group 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 Ospray Spray-Out to control resistant weeds.

 

Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with the chemical or used containers. This formulation should not be applied on or near water which is used for human consumption, livestock watering or irrigation purposes or water used for commercial or recreational fishing.

 

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.
