Abstract

The aim of this project was to establish the importance of verticillium wilt in winter oilseed rape and carry out initial work on varietal resistance and the impact of agronomic factors.

 

Between 2009 and 2011, verticillium wilt was confirmed in 16% of 292 randomly selected crops of winter oilseed rape that were sampled in late June. About 5% of crops had more than 30% of plants affected and the average level of verticillium wilt in England was 3.3% of plants affected. Verticillium wilt was found most frequently in eastern England, but it occurred in all regions and as far north as Yorkshire.
