Control of downy mildew on rose and herbaceous plants

This project will examine the most promising new products identified in the SCEPTRE HortLink project and elsewhere for control of downy mildews on two ornamental crops, and for their crop-safety to a range of woody and herbaceous ornamentals.  Simple crop protection programmes, based where possible on ‘low risk’ products and designed to reduce the risk of resistance build-up, will be devised and tested.  The HDC factsheet on downy mildew diseases (04/04) will also be updated.
