Abstract

Seed borne diseases can cause serious problems in organic cereal production because no fungicide treatments can be used and so far only few alternative treatments are approved. The effects of alternative seed treatments against net blotch (Drechslera teres) in barley and leaf blotch (D. avenae) in oats were investigated by laboratory tests and field trials at two locations in Norway in 2005. A barley seed lot with 65 % D. teres infected seeds and an oat seed lot with 15 % D. avenae infected seeds were used. The treatments included Inulex*, Terra Biosa**, acetic acid and Cedomon***, in addition to chemical seed treatment (triticonazol + imazalilsulfat) and untreated seeds as controls. Seeds were analysed for germination and pathogens in laboratory (2x100 seeds) and planted in rows of 100 seeds with 8 replicates in each field location. Percentage emergence and seedlings with primary infections were recorded at BBCH 12-13. Infection level of D. teres recorded in laboratory analyses were reduced significantly by Inulex and acetic acid. In field, the best effect was seen by the acetic acid treatment. The effects against D. avenae were generally poor in laboratory tests and the infection level of the oat seed lot used was too low to give primary symptoms in the field. Similar experiments will be carried out in 2006 and results from this will also be presented. *Extract of Inula viscosa. ** Containing lactic acid bacteria and different herbs. *** Commercial seed treatment (BIOAGRI), based on the soil bacteria Pseudomonas chlororaphis.
