Full Research Project Title: Comparative efficacy of available and new active ingredients in Great Britain
Duration: April 2003 - May 2007

Aim: To carry out an independent evaluation of blight fungicides and new active substances, in terms of the benefits of early season applications and efficacy of products

In 2003, the British AHDB Potatoes commissioned SAC and ADAS to carry out an evaluation of potato blight fungicides and fungicide programmes. At that time it was over 10 years since the last independent evaluation of blight fungicides and new active substances had been developed whilst others were no longer approved for use. The researchers looked at the benefits of early season applications and compared the efficacy of products available for use in the mid to end of season and manufacturers' programmes.

Results from the three seasons' trials are provided below. In 2006 and 2007, the effect of cultivar resistance rating and fungicide spray interval on the control of potato blight were evaluated. See Project R293 for further information.
