1 TECHNICAL MANUAL FASTER, STRONGER, LONGER THE FALLOW BOSS PROVIDING FAST KNOCKDOWN AND RESIDUAL CONTROL OF KEY BROADLEAF FALLOW WEEDS. Solutions for the Growing World

2 FASTER, STRONGER, LONGER FallowBoss TORDON provides fast knockdown and longer residual control of key fallow weeds including Fleabane Amaranthus Noogoora burr Thornapple Black bindweed Sow thistle And many more... FallowBoss contains three powerful active ingredients 2,4-D a foundation of modern agriculture Picloram the benchmark for hard to control weeds Aminopyralid strong new active that increases knockdown speed and reduces new weed germinations, especially under tough conditions. FallowBoss is registered for the control of flaxleaf fleabane and many other broadleaf weeds in winter cereals, winter fallow, summer fallow FallowBoss will NOT have an in-crop registration for summer cereals or sugar cane.

Aminopyralid is present in other Dow AgroSciences products that are used by growers where strong residual control is desired (for example Grazon Extra Herbicide and Hotshot Herbicide). Aminopyralid is what makes FallowBoss a stronger fallow product than the competition. BEST MANAGEMENT FOR FLEABANE. Dow AgroSciences supports the use of the double knock technique for fleabane control in fallow. Our trial work (and that of many others) confirms that a FallowBoss treatment followed -14 days with a Spray. Seed application can increase overall brownout and residual control, especially under difficult conditions. TORDON 75D a/ha STARANE ml/ha Control of flaxleaf fleabane, 28 days after application Fleabane plants were -15cm tall at application All treatments tank mixed with Glyphosate at 5 gai/ha +.2% v/v Chemwet (5 gai = 1.2 L/ha of a 4 g/l glyphosate)

Hotshot and Tordon 75-D are not registered for the control of fleabane in-crop.

See the label for further directions. The above tables display the differences between 75-D products and FallowBoss More work will be conducted this summer to determine if the above plantback periods can be reduced for FallowBoss. See the next page for other crops.

9 PLANTBACKS FOR RATES UP TO ML/HA 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 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 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.

These plantback periods are also required for fallow crops and are based on normal rainfall pattern. During drought conditions (or when rainfall is less than 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. CROPS PLANT-BACK PERIOD (MONTHS) Barley, Wheat 9 Canola 12 Chickpea, Faba bean, Field pea, Lucerne, Lupin, Medic, Subclover; Cotton NOTE: Before using FallowBoss TORDON Herbicide in tank mixes with other herbicides, check the plant-back information on all product labels. The most residual product, i.e. the product with the longest plant-back period, will determine the time between spraying and planting the next crop. It is recommended that a soil bioassay be conducted prior to planting a susceptible crop (see below for the method). Information presented in this brochure is to be used as a guide only and is not a substitute for the current full product label. Please read the product label before using FallowBoss TORDON Herbicide.
