Nufarm pre-harvest canola glyphosate use pattern registered
Oct. 3, 2014
Andrew Wells, Research and Development Manager for Nufarm, said the new registration was another way growers could help reduce the development of weed seed set into the following season.
“There are currently very few registered options for growers to control annual weeds prior to harvest and this registration will give growers more options to help reduce the weed seed set and the potential for herbicide resistance developing,” Mr Wells said.
As part of the approved registration, growers will be able to apply weedmaster DST, a 470g/L glyphosate, after 20 per cent canola seed colour change or under the cutterbar at time of windrowing. It can be applied at this time in all canola systems including Triazine Tolerant, Clearfield, Roundup Ready and conventional varieties.
The new registration, which was part of a three year, joint funded program between Nufarm and the Grains Research Development Commission (GRDC), is considered crucial by many in the industry to control annual weeds, such as ryegrass.
Trial results, as part of the registration process, showed that an application of weedmaster DST on canola at windrowing reduced annual ryegrass seed production by more than 70%, with similar results seen when applied to standing crops prior to harvest.
“The issue of weed seed set is particularly important when considering weeds like annual ryegrass and wild radish, which are both capable of producing thousands of weed seeds per plant and can be spread readily,” Mr Wells said.
“An application of weedmaster DST prior to seed formation in ryegrass significantly reduces this from occurring.”
Mr Wells said extensive trial data from Nufarm also showed there were no negative effects on canola crop yield or oil content and when weedmaster DST was applied according to the product label, there were no concerns regarding maximum residue levels for export grain.
“This is a great outcome for Australian growers and provides more options around weed control. Nufarm have completed extensive trials on pre-harvest glyphosate use and growers can be confident that weedmaster DST delivers excellent weed control when applied according to label recommendations.”
