Figure 3. Regional differences for the diseases hull rot (HR), lower limb dieback (LLDB), trunk disease and shot hole .
Adelaide Plains had less shot hole than the other regions. This may be due to smaller orchards allowing more effective spray coverage. Rust and anthracnose were observed in Western Australia but were rare elsewhere (data not shown).What's next? This research aims to improve our understanding of the major almond diseases affecting the Australian industry. Surveys and sampling will
continue throughout the 2019-2020 season. We have already completed the spring surveys and are gearing up for the pre-harvest surveys. Analysis of two years of data will provide guidance for identifying factors influencing disease and assist in the development of strategies for management in the future.
assess hull rot as close to Nonpareil harvest as possible.
It is weather-driven, so differences in rainfall between the regions will have influenced the incidence observed. Trunk diseases were more prevalent in Adelaide Plains, Riverina and Western Australia. In Western Australia, high soil salinity may contribute to the trunk disease symptoms observed.
