General Instructions

 

Minimum Recropping Periods

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

 

DO NOT plant susceptible broadleaf crops within 12 months of applying the product. Cereal crops and grasses can be sown safely after using Cheminova Unleash Herbicide for in-crop weed control.

 

Mixing

 

Unleash Herbicide can be mixed with water only. Mix only sufficient chemical for each days use and avoid storing mix. Half fill the spray tank with water and add the required quantity of Cheminova Unleash Herbicide and complete filling. Agitate continuously to ensure thorough mixing before and during application.

 

Tank mixtures: Wettable powder or dry flowable formulations (e.g. water dispersible granules) should be added to the spray tank first, followed by suspension concentrates (flowables), water soluble salts and then emulsifiable concentrate formulations (e.g. Fluroxypyr 200). Add spraying oils and surfactants (wetters) last, if required.

 

Compatibility

Cheminova Unleash Herbicide is compatible with the following:

(Read and follow all label directions, restraints, plant-back periods, withholding periods and safety directions on the partner label as well as those on the Cheminova Unleash label).

 

Broadleaf Herbicides - Eclipse* Herbicide, , MCPA 500, Cheminova Clopyralid 300, MCPA LVE, metsulfuron methyl, Fluroxypyr 200.

 

Grass Herbicides - Diclofop methyl 375 (annual ryegrass only), Topik 240EC (wild oats and phalaris only)

 

Adjuvants - BS-1000 (when mixed with metsulfuron-methyl), Uptake* Spraying Oil (when mixed with Topik)

 

Insecticides - Le Mat, Rogor.

 

Unleash is not compatible with zinc products (such as Zinc dextrase and Zinc heptahydrate), copper salts (such as sulphate) and manganese sulphate. Do not use with hard water or water clarified with alum.

 

Application

 

A. Ground Application (Boom) - Apply Cheminova Unleash Herbicide with an accurately calibrated boom sprayer, in at least 50L/ha water. Flat fan nozzles are recommended using pressures in the range 200 to 300 kPa. Set the boom at a height to ensure a double overlap of the nozzle pattern.

 

B. Aerial Application - Apply in a minimum volume of 35 L/ha water. Use equipment calibrated to produce droplets with an average diameter (Volume Mean Diameter) of 200 - 250 microns. DO NOT apply when the temperature is above 30C, when there is no wind or when the wind is blowing towards susceptible crops.

 

Sprayer Cleanup

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

 

Rinsing : After using Cheminova Unleash Herbicide, empty the tank completely and drain the whole system. Thoroughly wash inside the spray unit using a pressure hose. Drain, and clean any fi lters in the tank, pump, lines, hoses and nozzles. After cleaning the tank as above, quarter fill with clean water and circulate through the pump, lines, hoses and nozzles. Drain and repeat the rinsing procedure twice.

 

Decontamination (before spraying cotton and other sensitive crops; see PROTECTION OF CROPS): Wash the tank and rinse the system as above. Then quarter fi ll the tank and add an alkali detergent ( e.g. liquid SURF., OMO. or DRIVE. ) at 500 mL/100L of water or the powder equivalent at 500g/100L and circulate throughout the system for at least 15 minutes. Drain the whole system. Remove fi lters and nozzles and clean them separately. Finally fl ush the system with clean water and allow to drain.

 

Restraints

 

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

 

DO NOT use in high winds.

 

DO NOT spray if rain is likely to occur within four hours.

 

DO NOT apply close to, or on areas, containing roots of desirable vegetation, where treated soil may be washed into areas growing, or to be planted to, desirable plants, or on sites where surface water from heavy rain can be expected to run off to areas containing, or to be planted to, susceptible crops or plants.

 

DO NOT move soil which may have been sprayed to areas where desirable plants are to be grown.

 

Resistance Warning

 

Cheminova Unleash Herbicide contains members of the pyridine and phenoxy groups 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 this product or other Group I herbicides. Since the occurrence of resistant weeds is diffi cult to detect prior to use, Cheminova accepts no liability for any losses that may result from the failure of this 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 Cheminova representative.

 

Protection of wildlife, fish, crustaceans and environment

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

 

Protection of crop, native and other non-target plants

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

 

- Crops and plants susceptible to Cheminova Unleash Herbicide include but are not limited to clovers, medics, lupins, peas and other legumes, cotton, fl owers, hops, grape and kiwifruit vines, ornamentals, potatoes, saffl ower, shade trees, sugar beet, tobacco, tomatoes, tree fruits and vegetables.

 

- DO NOT use on land to be cultivated for growing susceptible crops within 12 months of applying Cheminova Unleash. Susceptible crops and plants can be damaged by soil residues during both growing and dormant periods. In the season following application of this product the regeneration or establishment of sensitive legumes (clover, medics, peas, lupins) may be adversely affected by soil residues. Cereal crops and grasses can be sown safely after using Cheminova Unleash Herbicide.

 

- This product will kill legumes (clovers, medics) present in the crop at the time of spraying.

 

- DO NOT apply close to or on areas containing roots of desirable vegetation, where treated soil may be washed to areas growing, or to be planted to desirable plants, or on sites where surface water from heavy rain can be expected to run off to areas containing or to be planted to susceptible crops or plants.

 

- DO NOT move soil which may have been sprayed to areas where desirable plants are to be grown.

 

- Cereal crops may be reduced in height following use of this product. This height reduction is a normal response and does not represent any yield loss.

 

- DO NOT apply Cheminova Unleash Herbicide to crops or pastures, which are to be used for the production of compost or mulches for use with susceptible crops or plants. The use of straw, hay or other plant material treated with Cheminova Unleash Herbicide for composting or mulching susceptible crops may damage these crops.
