Última Strategies for controlling seed-borne diseases in cereals and possibilities for reducing fungiside seed treatments Organic Eprints Nielsen, Bent; Borgen, Anders; Nielsen, Ghita; Shceel, Christiane. In the short term there is no useful alternative to chemical seed treatment for controlling the important seed-borne diseases in cereals. The only way to secure high quality seed is by discarding seed lots which have more than a specified level of disease. Without any other effective control measure than seed treatment large quantities of cereal seeds would be expected to be discarded. Another reduction model might be a differentiated use of seed treatments in the different certified seed generations. An important condition for the models is a representative seed test which for the moment only is possible in spring cereals. The threshold levels for the different diseases should under these circumstances be re-evaluated. In the long term other measurements...

In production of organic seed it is important to have some control measures on seed borne diseases to avoid propagation and spread of serious diseases. Due to lack of acceptable treatment methods the only way for the moment is to discard seed lots with unacceptable infections. Experiments have been started to find new and alternative methods for controlling seed borne diseases. In spring barley the results show good effect with 5% acetic acid on leaf stripe (Pyrenophora graminea) but problems with unacceptable effects on seed germination have to be solved. The old method with hot water treatment can be used and the results indicate good results against leaf stripe using water at 55°C. The effect of hot water was enhanced by first soaking the seeds in water...

Ano: 2000 URL: http://orgprints.org/1120/1/Controle_1120.htm Effect of seed treatment with acetic acid in control of seed borne diseases Organic Eprints Borgen, Anders; Nielsen, Bent. In field trials, seed treatment with acetic acid has reduced common bunt (Tilletia tritici) in winter wheat by 91.5-96.2% and by 83% in spring wheat without negative effects on germination vigour of the seeds. Leaf stripe (Pyrenophora graminea) in spring barley was reduced by 93,4%. Acetic acid is a cheap and environmental friendly fungicide with a possible scope of application especially in organic agriculture, where conventional pesticides are prohibited.
