Collaborative project: Development of non-chemical seed treatments for control of seed- and soilborne pathogens of maize - Subproject 4 (SaatMaisPlus)
Project
Project code: 2814902615, 2814908215
Contract period: 01.05.2017
- 30.09.2020
Budget: 251,625 Euro
Purpose of research: Applied research
Keywords: Sustainable plant protection
Aim of the project is the development of non-chemical seed treatment methods with activity against both seed- and soil-borne pathogens of maize. In order to achieve this goal, seed treatment with microorganisms will be combined with the physical method of electron seed treatment. This requires the adaptation of electron seed treatment to maize seed on the one hand while on the other microorganisms must be identified that after application to seed exert antagonistic effects on the relevant pathogens. The efficacy of the single methods and their combinations will be tested in greenhouse- and field experiments. The effect of the treatments on the content and distribution of fusaria in the maize plant will be assessed by molecular methods. Properties related to the antagonistic activity like ability to colonize roots will be studied in further laboratory experiments. Microorganisms with activity against relevant maize pathogens will be selected from a pool of pre-screened isolates. In parallel, the method of electron seed treatment will be adapted to maize. Efficacious strains, electron treatments and combinations thereof will be tested in greenhouse experiments as seed treatments for control of Fusarium, Rhizoctonia and Pythium. The most efficacious treatments will then be used in field trials with seed lots carrying pathogens or with healthy seed on sites with soil-borne pathogen attack. In laboratory experiments the root colonization of selected isolates will be assessed, and the effect of the treatment of the content and distribution of fusaria in the plant will be quantified by molecular methods.
