Última Control of seed borne diseases in production of organic cereals Organic Eprints Nielsen, Bent; Borgen, Anders; Kristensen, Lars. 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: 2001 URL: http://orgprints.org/1136/1/se.pdf Effect of seed treatment with milk powder and mustard flour in control of common bunt (Tilletia tritici) in wheat and stem smut (Urocystis occulta) in rye Organic Eprints Borgen, Anders; Kristensen, Lars. In field trials mustard flour was able to control seed borne infection by common bunt (Tilletia tritici) in wheat without decreasing the germination vigour of the treated seeds. Full control of common bunt by coating the seeds with milk powder could only be achieved at doses which reduced germination vigour of the seeds. Mustard flour can be recommended as a seed treatment in organic agriculture while a treatment based on milk powder should be developed in combination with biological control. Both milk powder and mustard flour can be used to control stem smut in rye (Urocystis occulta).

Ano: 2001 URL: http://orgprints.org/1115/1/1115.htm Forebyggelse af mykotoksindannelse i økologisk brødkorn - med fokus på Penicillium verrucosum og dannelse af ochratoksin A Organic Eprints Haase, Maiken S.. Mykotoksiner er giftige metabolismeprodukter produceret af svampe. Ordet er afledt af det græske mykês, der betyder svamp. Hvilke mekanismer, der regulerer svampemetabolismen og dannelsen af toksiner, og hvilken rolle metabolitterne har i svampenes livscyklus, ved vi stadig meget lidt om. Nogle af metabolismeprodukterne er til gavn for mennesker bl.a. ved anvendelse inden for den farmaceutiske industri, andre er skadelige. Ochratoksin A (OTA) er et eksempel på et af de skadelige metabolismeprodukter. Det er et af de vigtigste mykotoksiner globalt set, og sundhedsrisikoen for mennesker og dyr er blevet påvist. OTA er både nephrotoksisk, carcinogent, teratogent og immunotoksisk. I de tempererede områder forekommer OTA specielt i cerealier, hvor det...

Ano: 2003 URL: http://orgprints.org/1228/1/SpecialeprojektMaikenHaase.pdf 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.

Ano: 2001 URL: http://orgprints.org/1116/1/acidBCPC.htm Biological control of common bunt (Tilletia tritici) in organic farming Organic Eprints Borgen, Anders; Davanlou, Mehrnaz. Common bunt (Tilletia tritici syn. T. caries) is a significant seed borne plant disease in organic agriculture. General measures in ecological crop protection like crop rotation and manuring practice has in practice failed to control this disease, and direct seed treatment therefore seems to be necessary to ensure yield and food quality. Current study indicate that biological control can give successful control without negative effects on seed germination vigour. A combination of biocontrol agents and milk powder improves the effect of the biocontrol. Application of compost to the soil increases the frequency of this disease. The potential role of biocontrol within the principles of ecological disease management is being discussed.

Ano: 2000 URL: http://orgprints.org/1122/2/biocontrol.htm 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...
