Key messages

• At Malinong, SA currently registered products from fungicide groups 3, 7 and 11 did not provide high levels of powdery mildew control. This is consistent with previous findings from trials conducted in this project and SAGIT project TC120 across 2020 to 2022.

• Products from alternative modes of action (group 13) provided high levels of powdery mildew control. Septoria infection was also present at this site and must be taken into consideration when interpreting these results. 

• There was no or low levels of powdery mildew infection at the Bute, SA and Katamatite, Vic trial sites. These trials did not generate significant new data towards powdery mildew management strategies. 

• Field-based sensor surveys are providing some clues for differences in landscape position that might be important in powdery mildew development. Initial results reported here show temperature differences in July/August may be contributing to the differences in the level of powdery mildew infection. However, the results from one season of field monitoring are not sufficient to answer all research gaps. 

• Last season a number of regions were resampled (central and northern YP, mid-north, Victoria) for resistance testing to look at the change in G143A mutation frequency overtime.
