Application of alkylresorcinols in an organic apple orchard for protection against storage diseases
Each year, fungal storage diseases destroy large amounts of apple, especially in organic orchards. In the present study, antifungal activity of a rye bran-based remedy with 5-n-alkylresorcinols (ARs) was investigated. In 2014 and 2015, ‘Amorosa’ apple trees in an organic orchard were sprayed with a 0.025% AR emulsion pre-harvest, once or twice at different points in time. In addition, emulsions wi
