Dette er den første rapporten om potensialet for additivet NanoPro til å redusere doseringen av de to mest brukte fungicider for bekjemping av mikrodochium flekk (Microdochium nivale), den økonomisk viktigste sykdommen på golfbaner i Skandinavia. Forsøket ble gjennomført fra 14.sept. 2018 til 1.mai 2019 på en tunrappgreen ved NIBIO Turfgrass Research Centre Landvik. Bruk av NanoPro 292 ml/ha i tankblanding, først med det systemiske fungicidet Delaro® SC 325 den 19.sept.18 og deretter med kontakt fungicidet Medallion® TL den 15.nov.18 gjorde det mulig å oppnå samme sykdomskontoll med 30-60 % mindre dose av fungicid. Virkningen av NanoPro var bedre med Medallion® TL enn med Delaro® SC 325. Våre foreløpige data tyder på at NanoPro kan være et viktig hjelpemiddel for å redusere forbruket av soppmidler på golfbaner. Forsøket bør gjentas ett år for å dokumentere effekten av NanoPro igjennom en artikkel i et vitenskapelig tidsskrift.

This study investigated the effect of five different pre-treatment methods (ammonia (NH3), caustic soda (NaOH), dry milling, hot water and steam explosion) for straw for biogas production. The methods were selected based on their suitability for implementation in farm-scale biogas plants. The pre-treatment methods were applied to four different types of straw. Batch anaerobic digestion tests were carried out in bottles at mesophilic temperature (37 ± 1 °C). The straw was analysed for lignin, hemicellulose and cellulose. The results showed large variations in methane production following the different pre-treatment methods. There were also large variations between the pre-treatment methods in their effect on the different types of straw. Pre-treatment with NaOH on barley straw was particularly effective. The results also showed that the shorter the retention time in the reactor, the more important the choice of pre-treatment method. Different pre-treatment methods were found to be optimal, to some extent, for different retention times.
