Probiotic spray reduced incidence of fire blight in apple flowers

While many celebrate apple blossoms as classic signs of spring, they are also welcoming entry gates for pathogens. Full of nutrients to lure pollinators and promote pollen germination, flowers also attract bacteria like Erwinia amylavora, a pathogen that causes a damaging disease called fire blight.
