Get your canola paddock assessed for fungicide tolerance

In 2015 a survey of 200 canola paddocks found 15% of canola paddocks contained blackleg that was tolerant to Jockey fungicide (fluquinconazole). During 2018 Marcroft Grains Pathology (MGP) will repeat the 200 canola paddock survey across Australia. Each paddock will be tested for tolerance to Jockey and all other fungicides currently on the market, plus new chemistries that are forecast to be commercially available in the next two years.

To conduct this survey, we need your help. If you wish to be involved, we will screen your stubble and send you the results free of charge. All we need is 50 pieces of canola stubble from your paddock.

If you wish to be involved, please email Angela Van de Wouw ( with your expressions of interest, and she will email you an instruction form.  

We will provide results at the completion of the screens (probably around October). All results will remain anonymous and will be used to plan fungicide stewardship programs against the blackleg pathogen.
