Management of soil suppressiveness against soil-borne diseases Organic Eprints
Tamm, L.; Thürig, B.; Bongiorno, G.; Postma, J.; Fuchs, J. G.; Oberhänsli, T..
Soils suppressive to soil-borne diseases have attracted the attention of farmers and researchers for decades and many suppressive soils have been described. Microorganisms and soil microbial communities involved in suppressiveness have been studied intensively, but the underlying mechanisms are still not well understood. Suppressiveness to soil- as well as air-borne diseases has been shown to be highly site-specific. We will review how suppressiveness can be influenced by agricultural practices. Suppressiveness destroyed e.g. by steam sterilisation of soils could only be partially restored on the short-term by re-inoculation of soils, and the success of re-inoculation depended on the soil matrix as well as on the inoculum used. Long-term management (e.g....

Elicitors and soil management to induce resistance against fungal plant diseases Organic Eprints
Tamm, L.; Thürig, B.; Fließbach, A.; Goltlieb, A. E.; Karavani, S.; Cohen, Y..
Air-borne foliar diseases as well as soil-borne diseases can cause substantial losses in agricultural production systems. One of the strategies to overcome production losses caused by plant diseases is the targeted use of disease defence mechanisms that are inherent to plants. In this paper, the potential to enhance the plant’s health status either by inducing resistance through optimized soil management techniques or by foliar application of inducers of resistance is explored on the basis of a literature review and results from laboratory and field experiments. In our studies, the focus was on recent research about the use of dl-ß-aminobutyric acid (BABA) and an aqueous extract of Penicillium chrysogenum (Pen) as elicitors. We conclude that BABA as well...

Development of a botanical plant protection product from Larix by-products to protect grapevine from Plasmopara viticola Organic Eprints
Thürig, B.; Schärer, H.-J.; Ludwig, M.; James, E. E.; Langat, M. K.; Mulholland, D. A.; Kleeberg, I.; Tamm, L..
Extracts from European Larch (Larix decidua) were shown to be efficient to control grapevine downy mildew (Plasmopara viticola) under controlled and field conditions. Larixyl acetate and larixol were identified as the active compounds.
