Development of disease control strategies for organically grown field vegetables (DOVE) - OF0168

This study will aim to provide up to date information and advice to organic vegetable growers which will lead to safe expansion of UK production with minimal disease problems. The 3 year study will be composed of 4 specific objectives outlined as follows, together with ways in which they might be achieved: 1. Review of the significance of disease in organically grown field vegetables and the potential effectiveness of current control strategies under conditions of increased production. A search of UK and world literature will be conducted and information will be collated to produce a review and a list of major disease problems threatening organic producers. The review will be updated during the second and third years of the project with newly received findings; 2. Evaluation of novel techniques and strategies for control of diseases in organically grown field vegetables. Laboratory and field studies will be conducted to develop improved disease control strategies. In the laboratory, effects of different plant extracts on selected pathogens will be investigated, while field studies will involve the evaluation of paper and polyethylene mulches for pathogen control; 3. Monitoring of disease development in organic crops in relation to rotation and size of enterprise. Observations on disease progress and economic significance will be made on a range of vegetable crops grown in a standard rotational sequence; each phase will be represented each year of the study to allow observations on brassicas, alliums, legumes and potatoes each year at the same site over 3 years. Visits will be made on at least 3 occasions to monitor diseases in vegetables on organic holdings. Sites will be stratified to give geographic spread and to compare and contrast disease levels and economic appraisal for eastern England with the Midlands and the west; and 4. Production and publication of advisory literature for disease control in field vegetables. It is planned to produce at least 2 popular press articles and a conference paper. Comprehensive results of the study will be published in the form of a booklet at the end of the project.
