Planning for the 2019 season in WA – Sclerotinia management in canola

Conditions in Western Australia during the 2018 growing season were favourable for the development of sclerotinia in canola crops. Sclerotinia apothecia were first observed mid-July in Geraldton and persisted until September in many places. Infection in canola was detected as early as August with the first report being received in […]

Diagnosing disease: there’s an app for that

A range of smart phone and tablet apps and online tools, developed in conjunction with Australian plant pathologists and grains researchers, are helping farmers to identify crop diseases and construct appropriate management plans with just the push of a button. With smart phone and tablet adoption by farmers now exceeding that […]

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 […]

Retaining seed for the 2019 chickpea season

Kevin Moore from NSW DPI in Tamworth explains why it is important to look after and correctly store treated chickpea seed for the 2019 season. Most of the chickpea seed for the 2019 season will come from seed harvested in 2017 and treated with fungicide, as a lot of chickpea […]

Generating blackleg resistance groups

Blackleg resistance group testing

The Blackleg Management Guide not only provides blackleg resistance ratings but also blackleg resistance groups for current canola cultivars. But how do researchers determine these? Steve Marcroft talked us through how researchers establish resistance groups for canola cultivars, and more importantly, why you should know the resistance groups of the […]
