Fire blight mainly enters through twigs and the tips of tree branches. After that, the bacteria will travel to stems or trunks. It attacks the soft new growth first, causing the complete plant die-back to the roots. Once the bacteria attack any host plants, you will notice a burnt appearance on twigs and affected branches. This infection can also lead to the invasion of the entire root system, causing root rot disease.
Fire blight disease is tricky to control, especially when you reside in warm moist weather as the bacteria oozes out of the cankers speedily under such conditions. So, professional fire blight treatment solutions are crucial to retaining infected tree health and vigor.
