To evaluate the roles of varietal resistance and fungicide timing at Hart (MRZ, Mid North) and Calca (LRZ, Eyre Peninsula) for the management of net form net blotch (NFNB) of barley in the low and medium rainfall zones of South Australia
• In 2025, low NFNB pressure meant disease did not cause economically significant yield losses in either the medium or low rainfall zones.
• Fungicide applications, particularly at GS 31 and GS 39, reduced NFNB severity in susceptible varieties, however this did not consistently translate into yield benefits under low disease pressure.
