Over all four trials both Sakura treatments maintained a positive $ROI/ha with Sakura + trifluralin ($78.50) slightly ahead on average $ROI/ha to the standalone Sakura ($73.48)
Sakura 118 g/ha recorded a $55.08 increase in $ROI/ha over Boxer Gold across the four trials. Boxer Gold $ROI was generally in line with that of the prosulfocarb treatments in three of the sites, except from Waddy Forest where prosulfocarb 2.5 L/ha recorded a higher yield. Why this occurred is not clear as results were cross checked back with the contractor to ensure there was not a transcription error.
Trifluralin, due to its poor weed control, especially at Cunderdin, returned a slight positive $ROI/ha ($7.20) across the four trials.
All four sites to some extent were affected by frost which may have affected yield outcomes.
Getting weed control right is the key to ensuring the longevity of any herbicide but it also allows the crop it’s best possible chance of achieving its yield potential. Using a program of effective knockdowns and a product with a long residual activity like Sakura can deliver higher yields and returns across a variety of soil types and locations as seen across the four trials conducted during the 2016 season.

Acknowledgments |
To the grower’s (Patton, McIlroy, Butcher and Syme families) that each hosted one of the trials, thank you for all your work in sowing and maintaining the sites and your understanding when hosting field walks. Thanks to Living Farm for the harvest of Waddy Forest, Pithara and Cunderdin, and DAFWA at Nugadong. To Michael Macpherson from Imtrade Australia, thanks for the use of your early season assessments and allowing your trial to be included in this multi-site review. |
