The prohibition on the use of synthetic chemical crop protection products (CCPs) and hydroponic systems under European organic farming standards results in a range of challenges for protected organic cultivation systems. While effective biological and plant/microbial fermentation extract based CPPs for the main greenhouse pests are available, the control of seed-borne, foliar and in particular soil-borne pathogens can be a challenge for organic growers. This review summarizes the history of organic greenhouse production, approaches which are of limited suitability in protected systems (e.g., crop rotation), soil steaming/solarisation, resistant/tolerant rootstocks/cultivars and recent research focused on developing suppressive composts, alternative CPPs and integrated strategies for the control of seed-borne, foliar and soil-borne disease that are acceptable under European organic farming standards.
