General Instructions




- Follow any regional restrictions, and all directions and restrictions on the label, of any chemical mixed with Ospray Pickout Herbicide (eg. 2,4-D Amine).


- Ospray Pickout Herbicide is compatible with the following herbicides:

2,4-D Amine, DP 600, Metsulfuron methyl, Glyphosate 450, Starane 200, Glyphosate 490


- Ospray Pickout Herbicide is compatible with the following adjuvants, as per Directions for Use:

Uptake, Pulse, non-ionic surfactant (1000g/L)




- Mix only with water


- Half fill the spray unit with water, and add the required amount of Ospray Pickout Herbicide. Add the remaining water with the agitator running. If required, then add spray oils or wetters (surfactants). Maintain mechanical or by-pass agitation in the spray tank during spraying. Only mix sufficient solution for immediate daily use and avoid storing.





Weeds need to be actively growing for herbicides to have optimum effect. Delay treatment until all regrowth has had time to grow to approximately 1 metre in situations which have been bulldozed, slashed, burnt, ploughed or areas having a previous chemical treatment.


A - High Volume Spraying

- Thorough coverage of foliage to the point of run-off is essential, however, avoid excess spraying which is wasteful of chemical.


Hand Gun

- Apply the recommended mix to give full coverage of leaves and stems through a No.6 to 8 tip at 700 to 1500kPa (400 to 500kPa for St John's wort).

- A spray volume of 3000 to 4000L per infested hectare of 1 to 2 metre high blackberry (30 to 40L/100m2) should be used.

- Use 2000L of spray mixture/ha of Galenia infestation (ie. 20L/100m2 infested area).



- Apply the recommended spray mix to give full coverage of leaves and stems. The final volume of application should be similar to hand gun.

- A spray volume of 3 to 4L/10m2 infested area should be used.

- A spray volume of 2L/10m2 should be used for an area infested with Galenia.


B - Aerial Application

- Apply in 200L of water/ha using an aircraft to apply 100L per pass on a double overlap pattern using nozzle configurations to product droplets of 250 to 350 micron diameter.

- The potential for damage from drift can be greatly reduced by avoiding unsuitable spraying conditions and using spray pressure and nozzles to minimise the production of small droplets.

- DO NOT spray when wind exceeds 15km/hr and/or air temperature reaches 35C.


C - Controlled Droplet Application (CDA)

- Results similar to high volume spraying can be obtained used Micron Herbi or similar equipment. Select a nozzle to give a flow rate of 2mL/sec and sweeping action of approximately 1m/sec to ensure a droplet density of 20/cm2. Use a marking agent, as recommended by the equipment manufacturers, to check spray coverage. Also, consult directions provided by CDA unit.


D - Low Volume High Concentrate Application Techniques

- Good control will be achieved, similar to high volume application, where bush size enables good coverage of entire bush. Use a marking agent, as recommended by the equipment manufacturers, to check spray coverage.

- Gas Powered Gun: Apply 50mL shots to obtain uniform coverage of 4 to 5m2 of surface area of bush. This relates to 20 droplets/cm2 of leaf surface.

- Sprinkler Sprayer: This technique involves using a micro sprinkler that is connected to a hollow fibreglass rod attached to a pneumatic knapsack sprayer. Use at low pressures (50 to 200kPa) and apply with a slow sweeping action over the top of the plants ensuring even coverage on the leaves.


E - Boom Application

- Application in a minimum spray volume of 200L/ha for Galenia and St John's wort and 600L of water/ha for Sicklepod. Flat fan nozzles are recommended, using pressure in the range of 200-300kPa. Boom height must be set to ensure double overlap of nozzle patterns.




A - Boom Application

- Application of Ospray pickout Herbicide in a minimum spray volume of 50L/ha is recommended. Flat fan nozzles are recommended, using pressure in the range of 200-300kPa. Boom height must be set to ensure double overlap of nozzle patterns.


B - Blanket Wiper Application

- Blanket needs to be made from durable and wettable material with a rigid backing.

- Blanket should be rigidly mounted behind motorised vehicle (eg. tractor, 4-wheel drive vehicle) and set low but never touching the ground. The chemical solution should be fed to the blanket at a flow rate sufficient to keep the blanket wet but not dripping. In thick patches the blanket may require more frequent solution recharge (rewetting).

- Ideally, a scraper bar should be mounted in front of the blanket in order to scrape or damage the bark (but not sever the stems) prior to the blanket wiping the stems. 


Sprayer Cleanup


- After using Ospray Pickout Herbicide, empty spray unit completely and drain the whole system. Thoroughly wash inside the unit using a pressure hose. Drain the spray unit, and clean any filters in the tank, pump, lines, hoses and nozzles.


- After cleaning the spray unit as above, quarter fill with clean water and circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.



- Before spraying cotton and other sensitive crops with equipment that has been used to apply Ospray Pickout Herbicide, see PROTECTION OF CROPS, NATIVE AND OTHER NON-TARGET PLANTS section.


- Wash the tank and rinse the system as above. Then quarter fill the tank and add an alkali detergent (eg. liguid SURF, OMO, OMOMATIC, DRIVE at 500mL/100L of water or the powder equivalent at 500g/100L of water) and circulate throughout the system for at least 15 minutes.


- Drain the whole system. Remove filters and nozzles and clean them separately. Finally flush the system with clean water and allow to drain.


Rinse water should be discharged onto a designated disposal area or, if this is unavailable, onto unused land away from desirable plants and watercourses.


Minimum Recropping Periods

View Document




DO NOT apply to weeds which may be stressed (not actively growing) due to prolonged periods of extreme cold, moisture stress (water-logged or drought affected), poor nutrition, presence of disease, damage or previous herbicide treatment, as reduced levels of control may result.


DO NOT spray if rain is likely within one hour or if foliage is wet from rain or dew.


DO NOT burn off, cut or clear blackberry or other woody weeds for at least six months after spraying.


DO NOT apply by aerial application in wind in excess of 15 km/hr and air temperatures above 35C.


In areas prone to flooding treatment should commence after any annual flooding as such areas flooded within 9 months following application may have reduced results.


Resistance Warning


Ospray Pickout Herbicide is a member of the pyridines group of herbicides. The product has the disrupters of plant cell growth mode of action. For weed resistance management, the product is a Group I herbicide.


- Some naturally occurring weed biotypes resistant to the product and other Group I 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 the product or other Group I herbicides.


Since the occurrence of resistant weeds is difficult to detect prior to use, Ospray Pty Ltd accepts no liability for any losses that may result from the failure of the product to control resistant weeds. Strategies to minimise the risk of herbicide resistance are available. Contact your farm chemical supplier, consultant, local Department of Agriculture, or local Ospray representative.


Protection of wildlife, fish, crustaceans and environment

DO NOT contaminate streams, rivers or waterways with chemical or used containers.


Protection of crop, native and other non-target plants

- Crops susceptible to Ospray Pickout Herbicide include, but are not limited to: peas, lupins, lucerne, navy beans, peanuts, soybeans and other legumes, cotton, flowers, fruit, hops, ornamentals, shade trees and Pinus spp., potatoes, safflower, sugar beet, sunflowers, tobacco, tomatoes, vegetables and vines.


- Ospray Pickout Herbicide is damaging to susceptible crops during both growing and dormant periods. Grasses are normally unaffected and establish quickly after treatment.


- Picloram, one of the active constituents in this product, can remain in the soil for extended periods depending on soil type and application rate, rainfall, temperature, humidity, soil moisture and soil organic matter.


- DO NOT apply under weather conditions, or from spraying equipment, that may cause spray drift onto nearby susceptible plants/crops, cropping lands, pastures, waterways or native vegetation.


- DO NOT allow physical spray drift onto waterways, native vegetation and susceptible crops.


- DO NOT apply close to, or in areas, containing roots of desirable vegetation, where treated soil may be washed onto areas growing (or areas to be planted with) desirable plants.


- DO NOT apply on sites where surface water from heavy rain can be expected to run off to areas containing, or to be planted with susceptible crops or plants. DO NOT move soil, which may have been treated to areas where desirable plants are to be grown.
