Disease surveillance on winter grain crops in the GRDC Northern Region showed no major disease issues from July to September 2018. Joining with Dr. Kevin Moore, a chickpea pathologist from NSW-DPI (Figure 1), more than 60 chickpea crop paddocks across central Queensland, southern Queensland and northern NSW were visited. Very […]

Cereal seed treatment guides

Applying fungicides to cereal seed, or in-furrow at sowing, are common management practices for managing various seed borne and foliar fungal diseases – particularly smuts, net blotches, and powdery mildew. As with any input, it is important to choose the right product and rate to get optimum efficacy. It is also […]

However, dry conditions can also bring […]

Taking stock of what we know about Crown rot

Crown rot has long been present in Australian cropping systems, but the introduction of minimum tillage systems, changing rainfall patterns and increased heat events has meant an increase in the severity and prevalence of this disease. This article looks at the key findings from the recent review Crown rot of […]
