The Plant Management Network has released a new web presentation called “Fire Blight and Streptomycin Resistance.”

The webcast covers the biological mechanisms of fire blight and its history of growing resistance to streptomycin antibiotics.

The presentation also discusses management techniques such as: overwinter pruning, copper spraying and canker treatments; in-season antibiotic applications, insect control and other biological controls; and alternative non-antibiotic management tools and techniques.

The 18-minute presentation is available at
