Words: Arxada
Arxada continues to deliver new weed control solutions for farmers and growers in New Zealand.
After many seasons of field trials, followed by regulatory approvals, two new registrations have arrived!
In the past few months, Arxada has been granted registration of two new products for post plant pre-emerge applications for two new crops: Tango, for forage brassicas and peas, and Hustler, for maize grain and silage crops.
These new registrations are exciting because not only are these new options for farmers, but Arxada’s formulation and field science team have developed and trialed these products, using existing actives in the market which are now registered for new crops.
Hustler® contains 200g/L mesotrione plus 200g/L flufenacet in a suspension concentrate formulation, for selective post plant pre-emergence residual control of various grass and broadleaf weeds in grain and silage maize.
Flufenacet, in this formulation only, is a newly registered active ingredient for the maize market.
Historically used in other production crops in New Zealand, Arxada has conducted many seasons of trials with Hustler, co-formulated with mesotrione, which has demonstrated excellent crop safety and residual control of troublesome broadleaf weeds and grasses in maize crops at the pre-mergence stage.
These include barnyard grass, nightshades, redroot (amaranthus), speedwell, wireweed, and many more
This unique Hustler formulation of mesotrione and flufenacet together in the same drum, has an easy-to-use rate of 1L/ha.
Tango®, replacing Ombre®, contains 300g/L acetochlor plus 40g/L clomazone in a capsule suspension Encaps® formulation, for selective post plant pre-mergence weed control in forage brassicas, oil seed rape, seed brassicas and peas.
Acetochlor, in this formulation only, is a newly registered active ingredient for use in the various brassicas mentioned, and peas.
Weeds controlled at the pre-emergence timing include redroot (Amaranthus), barnyard grass, nightshades, chickweed, mayweed, shepherd’s purse, speedwell, summer grass and many more.
Replacing alachlor in Ombre with acetochlor in Tango has reduced the application rate from 4-5L/ha with Ombre, to 3-4L/ha with Tango.
Like Hustler, this newly-registered formulation has also been through rigorous field and storage testing, giving farmers confidence when using and storing the product.
For best results with these pre-emergence herbicides, or any product used at these stages, a well-cultivated seed bed should be prepared, free of clods and trash.
Follow up moisture is also required, either via rainfall or irrigation, to fully activate the product (refer to the label for specifics, and conditions to avoid).
Soil type and cation exchange capacity (CEC) should also be considered when using pre-emergent chemistry.
In the case of Tango, avoid use on very light soils (CEC20).
Weed control may be reduced on very heavy soils (CEC>30).
As always, please read and adhere to the label.
