4. Resistance management strategies
CropLife Australia has a new resistance management strategy for Group 11 fungicides (quinine outside inhibitors) in Powdery mildew control. The new instructions state: DO NOT apply more than two sprays per season of Group 11 fungicides. If two consecutive applications of Group 11 fungicides are used, then they must be alternated with a fungicide from a different activity group.
The resistance management strategy for Group 11 fungicides (quinine outside inhibitors) in Downy mildew control remains unchanged, however a similar recommendation for the application of strobilurin sprays for Downy mildew control is under review by the CropLife Fungicide Resistance Management Review Group.
In the interim, it is recommended that the Powdery mildew resistance management strategy for Group 11 fungicides be employed when putting together a Downy mildew spray plan for the 2010/2011 season.
5. Permits
