New Registration Will Ease Pressure on Cereal Growers

Rexade herbicide with Arylex active was officially registered by the APVMA (Australian Pesticides and Veterinary Medicines Authority) late Friday April 28. Rexade will bring the concept of a ‘one pass’ cereal application to a new level, with cross-spectrum weed control and broad compatibility, along with a wide window of application.

“Cereal growers had a tough time last year, with continuing rain and wet paddocks hampering their ability to get multiple herbicide applications on their crops. In many regions they only had one chance to get their post-em sprays on their wheat” explained Dow AgroSciences Cereals Marketing Manager, Dan Dixon. “Those farmers and agronomists who trialled Rexade were able to get all of their grass and broadleaf herbicides on in one application. Rexade has a wide window of application (GS13-31), so those who were in a difficult position early, were still able to get the spray job done. These experiences last year clearly show that Rexade will ease pressure on cereal growers, whether it is weather, other farm operations or other commitments, a one pass weed control application ensures the application goes on at the right time for the best result and saves time and money. Rexade allows farmers to do it once, and do it right.”

Rexade is registered for use in triticale and wheat (non-durum varieties). It will control brome grass, phalaris and wild oats, as well as providing suppression of annual ryegrass, barley grass and silver grass. Performance on these six grass weeds has been found to be similar to Crusader™ herbicide across all geographies. Broadleaf weed control, however, has been significantly enhanced by the addition of Arylex active, with more robust control on a number of species taking the list of labelled weeds up to twenty four. Better control can be expected on bedstraw, bifora (suppression), chickpeas, deadnettle, faba beans, field peas, fleabane (suppression), fumitory, lentils, medics, prickly lettuce, small-flowered mallow (suppression), sowthistle, subclover, and vetch (suppression).

“We are continuing to build our dataset to add further weeds to this extensive list” added Mr Dixon. “We know that Arylex provides very good control of Mexican and common poppies and several thistle species, we just need a few more trials to submit for a Rexade label extension. This will also include further compatibility work to provide more options to farmers going forward.”

Rexade currently has labelled compatibility with a number of other ag inputs. The most common tank mix will be with LVE 600 MCPA but there will be some times when a bit of metsulfuron, bromoxynil, Hotshot™ herbicide, Lontrel™ Advanced herbicide, Paradigm™, Starane™ Advanced or Stinger™ herbicide can help in the final weed control. It should always be applied with either BS1000®, Chemwet® 1000 or Spreadwet 1000 Wetting Agent at 0.25% v/v.

Mr Dixon explains that “As with most herbicide applications, best results are achieved when there is a healthy competitive crop with weeds that are actively growing, small and in low densities. The ability to tank mix Rexade and cause no decrease in grass control combined with the ability to use Rexade over all soil pH ranges and still allow winter cropping rotational flexibility is why many growers will be using Rexade over competitive products.”

Rexade also brings to the market Dow AgroSciences’ patented GoDRI™ RDT™ technology. This innovative water dispersible granule allows high active ingredient loading in a dry formulation with no tank residues. “It literally goes from dry to full dispersion in seconds, making it one of the easiest dry herbicides to mix on the market today. This is a fantastic formulation improvement over the old OD formulations that settle out and are hard to mix, store, and pour” stated Mr Dixon, “Our tech teams have achieved a fantastic result with this formulation science and have already received some global awards around this technology and we are excited about the benefits it brings to growers and contractors.”
