The project, in partnership with ADAS and the Association of Independent Crop Consultants (AICC), has assessed over 1,200 samples in its first two years, providing a wealth of information on oilseed rape diseases across the UK.
For more information on results from SpotCheck 2018/19 visit our blog here.
When samples are received by ADAS, they are incubated at room temperature for 2 – 3 days, to encourage the light leaf spot symptoms to express on the leaf surface. Each of the leaves is then individually inspected and assessed for light leaf spot, Phoma, powdery mildew and downy mildew. If the leaf is suspected to be displaying disease symptoms it is then inspected again under a hand lens or microscope.
The assessment findings are then emailed back within five working days, allowing for spray decisions to be made based on the results.

We know that growing oilseed rape can be challenging so we have gathered together everything you need to know about oilseed rape here
Nearly 300 people completed our OSR: Big Picture Quiz in autumn 2018. By cross-analysing the findings we’ve been able to pull out some of the differences between those growers averaging over 4.0t/ha compared with those averaging under 4.0t/ha
