Trial location(s) Rupanyup, VIC
Blackleg control locations
Aims

To compare different fungicides for control of blackleg.

Key messages
  • Where blackleg disease pressure is low, fungicide application is not necessary.
  • The greater the amount of canola grown, the more likely is an infestation of blackleg.
  • Consequently, in 2012, blackleg disease pressure may increase in the Wimmera and Mallee.
  • A buffer of 500m from the previous year’s canola stubble is desirable when selecting canola paddocks.
  • Growers should utilise the “Blackleg Risk Assessor” and the current “Blackleg Ratings” on the GRDC website.
