Features

Broad spectrum broadleaf weed control (brassicas, fumitory, thistles, legumes, poppies, deadnettle and many more).

Paradigm has been found to be physically compatible with a wide range of products. LVE 600 MCPA is a recommended tank mix for most situations. However, a broad range of broadleaf herbicides have been tank mixed in field studies and demonstrations with no issues to date.
Apply with Uptake® Spraying Oil, BS1000® , Chemwet® 1000 or Spreadwet® 1000.

Refer to the product label for the full ist of products Paradigm is compatible with.

Paradigm is a multiple modes of action herbicide for broadleaf weed control in winter cereals. It combines two powerful actives:

Arylex (novel subclass of chemistry called arylpicolinates - Group 4) and
Florasulam (triazolopyrimidine sulfonanilide chemical family -Group 2).

This unique combination means that Paradigm controls weeds resistant to other herbicide modes of action, such as glyphosate and triazine herbicides, giving you peace of mind.

Paradigm can be applied from 3 leaf (GS 13) to flag leaf emergence. Ideal timing is as an early post emergence application on small actively growing weeds, with 300–600 mL LVE 600 MCPA (GS 13-37).

Paradigm can be tank mixed with fungicides early, even in barley, for one pass weed and disease control. Alternatively, it can be used late, with 2,4-D amine or Starane™ Advanced for late germinating weeds.
Paradigm is most effective on small (2 to 6 leaf) weeds. Please refer to the Paradigm Arylex active label for the particular weed growth stage.
Paradigm has full winter crop rotational flexibility with both actives having a short soil half-life. Breakdown is by microbial activity and there are no crop residues in hay crops or in straw baled after harvest

Application

Ground application: minimum spray volume of 80 L/ha
Aerial application: minimum spray volume of 40 L/ha

For most weeds the application rate of Paradigm Arylex active is 25 g/ha.
For weeds that require the addition of LVE 600 MCPA, the MCPA use rate is limited by the cereal crop growth stage. For detailed application rates consult the Paradigm Arylex active Label.

Best results are usually achieved when Paradigm application is made under conditions which favour rapid plant growth. Weed control may be reduced when plants are stressed by a range of factors including, but not limited to: drought, water logging, prolonged or severe frosts, sustained high or low temperatures, poor nutrition (including deficiency and trace element toxicity), root diseases or previous herbicide application.
Final weed control may be reduced when the soil remains moist for an extended period following application, especially when row spacings are wide and/or crops are uncompetitive.

Best results are usually achieved when applied to small (2 to 6 leaf) weeds and under good growing conditions. Only weeds that have emerged at the time of application will be controlled. Treatment of crops or weeds that are stressed must be avoided.
Control may be reduced where weed density is very high and limits spray coverage.

Please refer to the Paradigm Arylex active label for the particular weed growth stage.

Paradigm granules are highly soluble in water and will dissolve rapidly once added to fast moving water. Maintain agitation at all times including during mixing as well as spraying.The following order should be followed (wait until each formulation is mixed before adding the next one):

Quarter fill the spray tank while maintaining agitation.
Add Paradigm® granules, using the mixing procedure above.
Add LVE 600 MCPA (if required).
Add wettable powders, water dispersible granules or suspension concentrates.
Add other emulsified concentrates.
Fill the spray tank to half full. Then add non-ionic surfactants or Uptake® Spraying Oil.

For spray rigs that have limited bypass agitation: As for most granulated formulations, pre-dissolve Paradigm in a bucket before adding them to the main tank. Add Paradigm while stirring until the granules have dissolved.

Spray rigs with pre-mix hoppers: For spray rigs that have a drop-down chemical induction hopper, three-quarter fill this hopper with water and have the rinsing sprinkler operating. Add Paradigm and when dissolved, transfer this batch into the quarter filled main tank. Continue to rinse the hopper until the entire product has washed through.

Stewardship

Harvest: Not required when used as directed

Grazing/Stockfood: Do not graze or cut treated crops for stock feed for 2 weeks after application.

Livestock Destined For Export Markets: When Paradigm is used as directed and the above withholding period is observed, livestock commodities are considered acceptable for export. However, export requirements are subject to change. Consult your exporter for updated information about specific market requirements

Fodder intended for export: Some countries have limits on the level of residue acceptable in animal feeds. Please consult your exporter before using Paradigm on crops destined to be used for export fodder.

When using Paradigm in a tank mix with another product, observe whichever Harvest or Grazing/Stockfood withholding periods that is the longer of the products used. .

Paradigm has full winter crop rotational flexibility with both actives having a short soil half-life. Breakdown in the soil is via microbial activity, so quickest breakdown occurs in warm, moist soil which favours the highest microbial activity.
Plant back intervals may be extended when more than 50% of the required rainfall totals are intermittent, light rain, which does not maintain soil wetting for at least one week.

Winter Crops
Crops to be sown	Minimum time from application to planting	Minimum rainfall requirement from application to planting
Barley, triticale, wheat	1 week	None
Oats	6 weeks	25 mm
Sub-clover, canola, chickpeas, faba beans, field peas, lentils, lupins, medic, vetch	8 months	100 mm

Summer Crops
Crops to be sown	Minimum time from application to planting	Minimum rainfall requirement from application to planting
Maize, sorghum	4 months	100 mm
Mung beans	5 months	150 mm
All other summer crops including: Cotton, sunflowers, soybeans	6 months	150 mm

Care must be taken when applying Paradigm Arylex active to minimise spray drift. For more detailed information on spray drift management visit apvma.gov.au/spraydrift
In all cases droplet quality must be coarse or larger.
DO NOT apply when wind speed is less than 3 or more than 20 kilometres per hour as measured at the application site.
DO NOT apply during surface temperature inversion conditions at the application site.

Refer to the Paradigm Arylex active label for detailed information regarding aerial application as well as mandatory no spray zones for both ground and aerial applications.

If spraying cereals (wheat, barley, triticale, oats) water
rinse is sufficient.

Empty the tank completely and drain the whole system. Thoroughly wash inside the tank using a pressure hose, drain the tank and clean tank, pump, line and nozzle filters.
Quarter fill the tank with clean water and circulate through the pump, line, hoses and nozzles.
Drain and repeat procedure twice.

Paradigm is potentially damaging at low concentrations to a range of crops including legumes and canola. A complete decontamination is required before spraying sensitive crops.

Wash the tank and rinse as above.
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.

Crops susceptible to Paradigm include, but are not limited to, grain legumes (summer or winter), millets (Echinochloa spp.), lucerne, pasture legumes, cotton, fruit, hops, ornamentals, potatoes, safflower, beets, sunflower, tobacco, tomatoes, all vegetables and vines.
