BRESOV D4.2 - Protocol and guidelines to maximize organic seed production and to control the sanitary quality of produced seeds in tomato, brassicas and snap bean

Summary

To increase the number of healthy organic seeds, we tested different agronomic factors which could influence the number of seeds produced in several organic farms in Europe and provide recommendations on relevant factors in this deliverable. Organic farming prohibits the use of conventional chemicals to control pests and diseases, so alternative solutions such as natural compounds as well as mechanical treatments were evaluated on seed against seed-borne pathogens. The optimal protocols and treatments to control main seedborne pathogens affecting tomato, broccoli and snap bean are presented in this deliverable. The results are relevant for breeders, seed multipliers and farmers active in organic
