Australia's battle to hold back blackleg has had its share of success

By Leeann Minogue November 12, 2019

Speakers at Syngenta’s launch of Saltro, a new seed treatment, explained that Australian farmers have a different, more conservative approach to blackleg. In 1973, said Steve Marcroft from Marcroft Grains Pathology in Australia, “blackleg completely destroyed the crop.” For 15 years after that, there was very little canola grown in Australia. In the late 1980s, […] Read more

New labels for blackleg resistance

New “groups” for blackleg resistance on some canola seed this spring

By Leeann Minogue April 4, 2018

Agronomists agree the best way to control blackleg in canola is rotation — only growing canola once every three years, at most. Besides rotations, scouting and fungicide can help in the fight against blackleg. And, last spring a new item was added to the list of blackleg-fighting tools: a new labelling system. This season, you’ll see some new letters on some of your seed […] Read more
