Project code: 2814200906
Contract period: 01.09.2007

Budget: 381,671 Euro
Purpose of research: Experimental development
Producers of seed-grown ornamentals are struggling with numerous seed- and soil-borne pathogens. For this reason, the project aimed at developing and implementing a concept involving seed testing, seed treatment and seed applications for a number of host-pathogen combinations that occur in ornamental horticulture. The project focused on the use of antagonistic microorganisms in the form of licensed microbial plant strengtheners for pathogen control. In the process of developing combo tests for the simultaneous determination of germination capacity and detection of pathogens, the tests were found to be inappropriate for use in real-world conditions because they were not specific enough. The project succeeded in developing seed application methods and coating materials such as biopriming, encrustation, coating or empty pellets with microbial and non-microbial plant strengtheners, crop protection agents and combinations of microbial plant strengtheners with crop protection agents. However, applying microcapsules to seed in order to protect the antagonists was not feasible technically. The trials conducted as part of the project showed that seed applications of plant strengtheners to control pathogens had an effect in later stages of cultivation. However, the effect was not reliably reproducible even after the application had been optimised. Various procedures of thermal seed disinfection that did not affect germination capacity were fully developed for practical use on a number of project crops.
