More than 10 years after Australian growers first had access to Group 27 chemistry, the release of Frequency Herbicide gives farmers a bigger range of better choices for the in-crop control of broadleaf weeds. 

BASF Australia has launched three new herbicides in four years. And in each case ‘new’ really does mean new: each of the three – Luximax, Voraxor and Frequency – has introduced a new active ingredient exclusive to that product. In Luximax’s case it even has a mode of action group all to itself.  

“Growers and agronomists will be well aware that a lot of ‘new’ products are actually existing actives repackaged with a different brand name,” says Roger States, BASF’s Cereals Portfolio Manager. “They have a place, of course, but new chemistry is so much more valuable. Even when the new active is from an existing mode of action group, it is generally a step up in terms of efficiency and can mitigate some cross-resistance issues. That’s certainly the case with Frequency.” 

The new active in Frequency is a more potent Group 27 alternative to pyrasulfotole, which was first introduced way back in 2007 and until this year was only available in pre-mixed co-formulations. 

“Frequency provides the same levels of control at a lower application rate than any of the pyrasulfotole formulations,” Roger explains. “Based on trial data we can say that Frequency’s active, topramezone, is the most robust of all the Group 27 herbicides. It’s very potent while also providing excellent crop safety. The single, convenient application rate – 200 mL/ha – can be mixed with either bromoxynil or LVE MCPA at the most appropriate label rates to control all the key broadleaf weeds up to the 6-leaf stage.” 

Roger says Frequency has a particularly good fit in the northern cropping zones on the east coast. “We think Frequency should now be the preferred in-crop Group 27 herbicide in all areas, but growers in northern New South Wales and Queenland can get even more value from it than the rest of the country. First because it has a bonus registration to suppress wild oats in those areas, where Avena sterilis is the dominant species. Then there’s its very favourable re-cropping intervals, which allow crops like sorghum, sunflowers, all the pulses and cotton to be sown just 4 months after Frequency has been sprayed on the winter crop.”
