Control of fire blight in Baden-Württemberg at the end of the streptomycin era

A strategy for fire blight control at the end of the streptomycin era in Baden-Wuerttemberg was presented. In field trials, the products “Blossom Protect” (Aureobasidium pullulans) and “LMA” (potassium alum) gave consistently high efficacies, close to streptomycin. Therefore the advice of the plant protection service for 2013 was to use Blossom Protect preferably in the beginning of bloom, LMA during full bloom and at the end of bloom depending on infection risk and sensitivity of the cultivars to russetting.
