In-season monitoring
In 2004 and 2006, five oilseed rape crops were monitored to provide regular updates on disease severity and crop
development. From the end of September, the assessments were carried out weekly until December, then monthly until the end of April 2006. A final assessment
was carried out during pod filling.

National Surveys
Oilseed rape is the third most important crop (after wheat and barley) in the UK in terms of the area grown and fungicide inputs.
The incidence and severity of diseases varies from crop to crop and from season to season and are affected by agronomic practice and
by the weather. A national survey of winter oilseed rape diseases has been undertaken annually since 1987 to monitor changes in
incidence and severity of disease.
Approximately 100 crops are monitored for diseases at three times throughout the season; 25 plants from each crop are
assessed in the autumn during leaf production, in the spring and in the summer during pod ripening.
A proportion of crops are also sampled for pests during spring/summer.
