The National Brassica Pathology Working Group, comprising pathologists, agronomists, chemical companies and canola breeders from across Australia, unilaterally shared concern at a recent meeting in Melbourne that growers would potentially face serious risk of crop failure due to blackleg if attempting to grow canola on canola... Growers are urged not to risk the long-term viability of the canola industry by sowing canola on canola," said Dr Marcroft, on behalf of the National Brassica Pathology Working Group... Dr Marcroft, who has been addressing GRDC grains research Updates in the southern region about the blackleg scenario, says growers can use the Risk Assessor to determine if their paddocks are in a high risk situation, and what practices could be changed to reduce yield loss from blackleg.

" GRDC Grains Research Updates March 2-3, 2011, Northern Region, Goondiwindi QLD, Jack Christopher 16 September 2013 Dr Jack Christopher, QAAFI, talks about frost risk and sowing dates... Delayed planting is essential to avoid crop loss due to frost but severely limits yield potential... Variety guides and decision support software are invaluable tools for matching of cultivar to planting opportunity to maximise yield with acceptable frost risk...

For most parts of the northern grains region, there is a very high probability that crops flowering in July and August will be lost to frost damage (Figure 1)... In the northern grains region conflicting climatic influences including moisture availability and high temperatures severely constrain the timing of winter cereal flowering and grain filling if yield potential is to be maximised in face of frost risk (Figure 3)... In the absence of frost resistant winter cereals genotypes, our main strategy to minimise crop losses while maximising yield potential is to aim to achieve crop flowering and grain filling in the short window of opportunity following the main frost risk period (Figure 3)..
