NY97011 - Technology Transfer of Integrated Control of Downey Mildew

Downy mildew is a major disease of seedlings in nurseries, especially of pansy, brassicas, stock, alyssum, lettuce and poppy and of the shrubs, hebes and roses. Integrated management strategies, including fungicide treatments, were developed through two recently completed Horticultural Research and Development Projects. The aim of the work reported here was to facilitate the adoption of the research by the nursery industry through a series of seminars, workshops, conferences, nursery visits and various published media. It was found the incidence of downy mildew was high on Brassica seedlings in one nursery during 1995, prior to adoption of the integrated management strategies, but after adoption of these strategies in 1996 was reduced by up to 100%.
