CRT SA : Super Summer Savings 2012

Crop Protection With the canola harvest almost over in many areas of Australia, the relative performance of many cultivars is being brought into question, as is the efficacy of different herbicide resistance systems and the strength of black leg resistance. The good news for canola growers this year is that there are fewer new cultivars to choose from than in previous years. This should make the selection of new lines easier, however, the variable performance of some preferred lines may shorten their lifespan, especially open pollinated lines that have not been refreshed in the last 3-4 years. If you’re in a high yielding canola region, hybrid canola should be at the top of your shopping list. Most lines provide exceptional yield and solid black leg resistance. Your hardest decision will be determining which herbicide resistance system will be best for your farm and cropping rotation. Every canola growing area of Australia has its own specific issues with herbicide resistance and these will need to be taken into consideration when planning the 2013 crop. Many areas have annual ryegrass which is resistant to Group A, B and D herbicides whilst other areas have wild radish that is tolerant to triazines. Such issues make appropriate selection difficult. The risk of resistance to the most important herbicide, glyphosate, also needs to be taken into consideration. The major development in canola over the last 3-4 years has been the introduction of Roundup® Ready technology. This technology has really taken off in Western Australia with more than 125,000ha planted this year. High yields and good weed management have been key to this growth. Further improvements will be seen with the introduction of a ‘Flex’ gene which will allow later applications of glyphosate to target later germinating weeds. Driving this increase in yield has been the adoption of hybrid canola lines which are more suited to higher rainfall areas. 2013 will see both hybrid and open pollinated lines available through Pacific Seeds, Canola Breeders and Nuseed. Canola Breeders have 4 new lines for next season with a number of new triazine tolerant lines including both OP and hybrid lines. CB Nitro HT is an early-mid line and CB Atomic HT is a true mid. Both these lines are hybrids with high yield potential which link in with CM Henty and CB Jardee. CB Sturt TT is an OP triazine tolerant line in the early-mid category. CB Status RR is a new OP Roundup Ready line which will grow well in more marginal areas as an early line taking this new technology further into the drier areas than before. Pacific Seeds is consolidating its range this year with a limited number of new releases being added to their strong line-up which has performed well over the last couple of seasons. Both new lines are hybrid triazine tolerant. Hyola 559TT is an early-mid season hybrid variety which will eventually replace Hyola 555TT. Hyola 656TT is a mid-long season variety for the higher rainfall areas and is slightly quicker than Hyola 751TT which it will replace. Nuseed will introduce a number of new lines to their long list of straight canola lines as well as a range of healthy oils coming through the monola program. Nuseed has 3 new Roundup Ready canola lines for 2013 including GT-41 , which is an early hybrid, and GT-50 which is an early- mid. Both lines should have very good black- leg resistance. The third Roundup Ready cultivar is an open pollinated mid season monola called NP0549. Also being added to the Nuseed monola range is an early-mid triazine tolerant line, NL0606, which is open pollinated with pending MR blackleg resistance. The Nuseed monola program pays farmers an additional earn over conventional canola and is limited to regions where Nuseed has arranged delivery points.
