Fire Blight
Fire blight can cause severe damage to apple and pear trees. Fire blight usually attacks blossoms, but infection and dieback of new shoots are common. The downward curled twig tip is characteristic of fire blight.

Cut off infected twigs and branches 12 inches below the dead area. Disinfect pruning tool between cuts by dipping in 10% solution of liquid bleach to avoid spreading disease. Use a harpin protein-based product as a preventive spray during bud break.

Spray every seven to 10 days at a rate of one-half to three-fourths cups per gallon. You can also control fire blight by spraying a copper soap product at silver tip and bud break, and repeat at three to five day intervals as needed, up to petal fall.
