In this study Wageningen UR Greenhouse Horticulture developed together with LTO Glaskracht Nederland and a group of growers, advisors and producers a sustainable control strategy for mildew. Several green products with a systemic or a contact mode of action were tested on their contribution to a resilient plant system. Three systemic green products were able to stimulate hormonal signalling pathways against biotrophic organisms and effective combinations were possible with biological green products. This research shows the first proof-ofprinciple that in a young plant system with smart combining of green products infection of mildew spores can be prevented. Follow-up research in multiple cropping systems with longer cultivation periods have to indicate what the impact is on the disease development over a longer period of time under more commercial growing conditions. For the development of (early) indicators of plant resilience, it is clear that multiple measuring methods are needed at the same time, during a certain cultivation phase, because the germination and infection is dependent of several climate and plant factors.
