Learn strategies and practices to control fire blight in apple and pear orchards without the use of antibiotics. Several new control materials are available for use by organic growers, but none appears as a stand-alone replacement for antibiotics.

We’ll cover sanitation, vigor control, sequence and timing of control materials, spray coverage, and varietal susceptibility.
