Strobilurin resistance in Septoria tritici blotch confirmed in South Australia Australia
Wheat growers are being urged to monitor the effectiveness of fungicides this season after the common wheat disease, Septoria tritici blotch (STB), was discovered to be resistant to Group 11 fungicides (strobilurins). As a result, researchers are now encouraging growers with any concerns about the effectiveness of Group 11 fungicides this season to send crop samples to CCDM for resistance testing.
Growers and agronomists who suspect reduced sensitivity or resistance to Group 11 fungicide should contact the CCDM’s Fungicide Resistance Group at frg@curtin.edu.au. Alternatively, contact a local regional plant pathologist or fungicide resistance expert to discuss the situation. A list of contacts is available on the AFREN website.
