This disease is influence by seasonal weather and prefers to attack the plant ’s blossoms , step by step moving to the branchlet and branches of the flora . It make the blossoms and sprig to have a burnt appearance , arrive at distinguish this disease easy .
The Lifecycle of Fire Blight
This bacterium winter in the cankers on the twigs , branches , or trunks of the host trees . Then , in the spring , when the atmospheric condition start to get warmer and moist , a small figure of cankers become alive again . The bacterium starts to spread and multiply .
This bacteria spreads via wind , hail , or insects , so if it finds a tree or shrub with injuries on the young leave-taking or shoot , it can easy invade . It spreads rapidly when the atmospheric condition is warm yet rainy or humid .

Tips of the shoot rapidly wilt , constitute a recount - story shepherd crook - similar figure . The leafage on the shoots might have melanize along the midrib and veins before becoming fully necrotic . legion diseased shoot give the tree a burnt appearance .
The contagion distribute through the residual of the Sir Herbert Beerbohm Tree , causing the flowers to turn brown . The sprig and flowers droop , shrivel and blacken , then they curl at the ends . When flak blight has fourth dimension to spread and become spartan , cankers form on the offshoot that ooze .
