This trial was established to determine the effects of an intensive autumn spray protection programme on Gold3 and Hort16A. It was difficult to separate treatment effects as the Gold3 site had little infection and the Hort16A site had too much infection. There was a trend for treatment programmes including a full programme with coppers, foliar applied elicitors and KeyStrepto™ to reduce the effects of Psa-V by comparison with other lesser treatment programmes.
