Fireblight Control in Your Trees

Fireblight is a very damaging disease to pyrus and malus species of trees. In our area these trees include pear and flowering pear, apple and crabapple. Fireblight may also affect toyon, hawthorn or cottoneaster. Fireblight spreads during rainy periods and enters tree tissues through blossoms. The blossoms will turn black and wilt. The pathogen then moves into twigs and branches which develop cankers. These cankers may ooze and can be identified by dark streaks on the branches. The foliage wilts and browns giving the tree a burned appearance which the name fireblight is derived from.
