GENERAL INSTRUCTIONS
MINIMUM RECROPPING PERIODS following application in cereals and fallow
Aminopyralid and picloram remain active in the soil for extended periods depending on rate of application, soil type (clay  content), rainfall, temperature, humidity, soil moisture and soil organic matter. The following tables show plant-back periods to particular crops following application of FallowBoss TORDON Herbicide in Queensland and NSW.
Northern New South Wales & Queensland
Plant-back periods for rotational crops following application of FallowBoss TORDON Herbicide up to 700 mL/ha on black cracking clay soils. These plant-back periods are also required for fallow crops and are based on normal rainfall pattern. During drought conditions (or when rainfall is less than 100 mm for a period of 4 months or greater) the plant-back period may be significantly longer. Under such circumstances a soil bioassay is required, before planting the next crop.
MINIMUM RECROPPING PERIODS following application in pastures
Due to the wide variation in application rates and methods of application recommended for pastures a minimum or 12 months should elapse between application and planting a susceptible crop AND a soil bioassay should be conducted before sowing. A simple bioassay can be conducted by collecting at least 10 spade spits of soil to a depth of 200 mm from around the paddock and thoroughly mixing the soil together. Place some of this soil in a shallow container to a depth of 3-5 cm and sow 100 seeds of the susceptible plant to be grown (subterranean or white clover is a good indicator plant where it is not practical to use the susceptible plant) into the soil. Keep in a warm and well lit location and ensure the soil does not dry out. After crop emergence, check the number of plants that have germinated and seedling vigour.
Symptoms of FallowBoss TORDON Herbicide residues include non-germination or low plant emergence, leaf cupping,  leaf whitening, stem elongation and twisting. If these symptoms occur – do not grow the susceptible plant. Repeat the bioassay again after a further time interval.

MIXING
Mix only with water. It will not mix with oil or diesel fuel. Mechanical or by-pass agitation in the spray tank is recommended, and it should be maintained during spraying. Quarter fill the spray tank and add the required amount of herbicide in the following order: Wettable powder or water dispersible granules; suspension concentrates (atrazine flowable); aqueous concentrates (e.g. FallowBoss TORDON Herbicide, 2,4-D amine); emulsifiable concentrates and finally surfactant or crop oil.

ADJUVANTS
DO NOT add surfactants or crop oils (such as Uptake Spraying Oil) unless specifically recommended to do so in the DIRECTIONS FOR USE tables. Use only BS1000 Biodegradable surfactant or alternatives Chemwet 1000,  and Spreadwet 1000 Wetting Agent. Not all surfactants or crop oils are of equal quality. Dow AgroSciences does not support the use of alternative products other than those listed in the compatibility section.

APPLICATION
FallowBoss TORDON Herbicide may be applied by:
Ground boom. Apply in 50-100 L water/ha using a coarse spray through accurately calibrated equipment. Misting machines and boom jet sprayers should not be used for treating crops.
Aerial Application. Use accurately calibrated equipment to deliver not less than 20 L water/ha.

COMPATIBILITY
FallowBoss TORDON Herbicide is compatible with:
- atrazine (600 g/L flowable or an equivalent granular product)
- Dow AgroSciences Amine 625 (2,4-D)
- diquat
- metsulfuron-methyl
- glyphosate 450
- Ripper™ 480 (glyphosate)

CLEANING SPRAY EQUIPMENT
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 FallowBoss TORDON Herbicide, empty the tank completely and drain the whole system. Thoroughly wash inside the spray unit using a pressure hose. Drain, and clean any filters 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, NATIVES AND OTHER NON-TARGET PLANTS):
Wash the tank and rinse the system as above. Then quarter fill the tank and add a standard alkali based laundry detergent at 500 g (or mL)/100 L water and circulate throughout the system for at least 15 minutes. If using a concentrated laundry detergent use 250 g (or mL)/100 L water.
Do not use chlorine based cleaners.
Drain the whole system. Remove filters and nozzles and clean them separately. Finally flush the system with clean water and allow draining.

RESISTANT WEEDS WARNING
FallowBoss TORDON 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 difficult to detect prior to use, Dow AgroSciences Australia Limited 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 Dow AgroSciences representative.
