Monsanto has released replicated demonstration trial results from a trial site based at Wallendbeen, NSW. The trial ran during the 2009 canola season and was focused on comparing the leading Roundup Ready, triazine tolerant and Clearfield® canola varieties.
In the first of many replicated trial sites this year, the results again show Roundup Ready canola having a significant yield increase over triazine tolerant canola, as initially demonstrated in 2008 – its first year of commercial release.
“Our trials with Roundup Ready canola have shown an 11 percent yield increase above the triazine tolerant varieties which is consistent with our previous findings and with growers’ experience. This proves you don’t need to sacrifice yield for weed control,” Dr James Neilsen, Monsanto canola technical specialist, said.
The trial also demonstrated that yields from Clearfield varieties were impacted by heavy weed pressure from Group B herbicide resistant weeds.
This trial highlights the importance to growers of the benefits of the Roundup Ready system, as it provides an alternative to other herbicide control systems.
“This is another tool in the grower’s toolbox and offers real choice to growers. Roundup Ready is a more flexible and environmentally friendly herbicide control system and, as it is a non-residual herbicide, you could say it’s a cleaner and greener canola,” said Dr Neilsen.
More data will be released in the coming months as other trial sites are harvested.
