The efficacy against fire blight of 3 antagonistic bacterial isolates (48M, 59M, 141M), strain C9-1 ̶ the active component of BlightBan (USA), the yeast based preparation Blossom Protect and copper preparations (Flow Brix 380 SC, Cuproflow 375 SC, Miedzian 50 WP) was evaluated on apple blossoms on Idared trees and Jonagold cut off branches. The highest efficacy was demonstrated after protective use of all bacterial isolates (82.7–92.0%) and Blossom Protect (83.5%). Miedzian 50 WP at the dose of 1.5 kg/ha appeared to be low effective. Two treatments with Blossom Protect applied during the blooming of apple trees cultivars Golden Delicious and Jonagold did not cause phytotoxicity on apples assessed after harvest. Because most fungicides used for protection of apple against fungal diseases are toxic to yeast in Blossom Protect, it seems that this preparation could be applicable against fire blight only in organic growing of apple.
