Previous research conducted at Horsham has found that canola plants infected after the third to fifth leaf stage did not result in the formation of a stem canker... The aim of the work was to investigate the use of foliar fungicides on canola seedlings as an alternative or in addition to the application of a seed dressing for blackleg control in areas of high disease pressure... Results from the field experiments suggest that the addition of a seed dressing and the application of a foliar fungicide gave the best protection...

Choose a cultivar with adequate blackleg resistance for your region... For individual site results consult the NVTonline website... Background: Blackleg disease can be minimised by a number of factors including sowing cultivars with high blackleg resistance, avoiding sowing in close proximity to last year's stubble and applying fungicides (see the current Blackleg Management Guide for details www.grdc.com.au)...

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.

The fungal disease 'blackleg' is the most severe disease of canola in Australia, causing yield loss and in some circumstances total crop failure... Blackleg is primarily controlled by breeding disease resistance into canola cultivars prior to release to industry... The project will assess the level of blackleg resistance in all canola cultivars enabling growers to select a cultivar that is suitable for their farming system and climatic region...

The large areas sown to canola in 2011 and the predicted increases in the area sown to canola in 2012 in southern NSW and northern Victoria will increase blackleg severity and increase the likelihood of yield losses... The aim of the work was to investigate the use of foliar fungicides on canola seedlings as an alternative or in addition to the application of a seed dressing for blackleg control in areas of high disease pressure... Results from the field experiments suggest that the addition of a seed dressing and the application of a foliar fungicide gave the best protection...

By screening and field testing the resistance and tolerance of wheat and barley cultivars, relevant information can be supplied to allow growers to incorporate cultivars into rotations that limit the populations of and damage caused by nematodes... Significant yield impacts occurred for wheat varieties assessed in Toodyay 2012 when comparing yield to nematode numbers at anthesis (Table 2)... Coupled with resistance data, these results indicate Emu Rock may be only moderately susceptible but very intolerant to P. teres while the other varieties are intolerant but range in levels of susceptibility to the pest...
