The need for a supply of high quality organic vegetable seedsS.P.C.GrootauthorH.JalinkauthorJ.KöhlauthorC.J.LangerakauthorA.MichtaauthorS.WernerauthorJ.M.van der WolfauthorR.W.van den BulkauthorProduction of high quality organic vegetable seeds encounters several challenges. Research is performed to support seed companies in producing vigorous and healthy organic vegetable seeds. Examples are provided with respect to research on seed vigour, determining critical control points to avoid disease transmission to the seeds, seed treatments with natu-ral compounds, new seed sorting techniques and enhancement of the natural plant defence. It is noticed that the restrictions in EU regulation 2092/91 on organic production are at present blocking the use of promising natural and sustainable components for seed treatments.Crop health, quality, protection Breeding, genetics and propagation2006Conference paper, poster, etc.
