A TRIAL undertaken by a canola pathology business has found that while the active ingredient of the popular canola seed treatment Jockey is no longer effective in controlling blackleg in all situations, canola growers still have options for control of the disease.
Marcroft Grains Pathology and the University of Melbourne worked on a project funded by the Grains Research and Development Corporation (GRDC) that found has shown that whilst fluquinconazole seed treatment is no longer 100 per cent effective in approximately one in seven paddocks tested, several other fungicides from the same mode of action group remain unaffected.
All seed-applied fungicides currently registered for blackleg control in canola are from the same mode of action group, the Demethylation Inhibitors or DMI-fungicides.
University of Melbourne researcher, Dr Angela Van de Wouw said the news was heartening.
“Because fluquinconazole is from the same mode of action group as some other fungicides used on canola, we were concerned there may be reduced effectiveness across the different active ingredients.
“But our research to date shows positive news for growers – fluquinconazole-tolerant blackleg isolates showed no change in susceptibility to either prothioconazole plus tebuconazole applied as a foliar application or flutriafol applied in-furrow.
