There are many diseases unfortunately that can attack your trees. I have experience in identifying and treating many various diseases including the following:-
• Acute oak decline (AOD) is a condition known to be affecting several thousand oak trees, mostly across East Anglia, the Midlands and Southern England as far west as Somerset. It affects both of Great Britain's native oak species:
pedunculate oak (Quercus robur) and sessile oak (Quercus petraea); as well as other species of oak.
• Chalara dieback of ash, also known as Chalara or ash dieback, is a disease of ash trees caused by a fungus called Hymenoscyphus fraxineus. (The fungus was previously called Chalara fraxinea, hence the name of the disease. See 'The Science' below for an explanation of the name change.) Chalara causes leaf loss, crown dieback and bark lesions in affected trees. Once a tree is infected the disease is usually fatal, either directly, or indirectly by weakening the tree to the point where it succumbs more readily to attacks by other pests or pathogens, especially Armillaria fungi, or honey fungus.
• Chestnut blight is a plant disease caused by the ascomycete fungus Cryphonectria parasitica. This pathogen has caused severe epidemics resulting in death and dieback of American sweet chestnut in North America and European sweet chestnut in continental Europe after its identification in North America in the early 20th century and Europe in the 1930s. It was first identified in Europe, in Italy, in 1938.
• Dothistroma Needle Blight (DNB), also known as Red Band Needle Blight, is caused by the fungus Dothistroma septosporum. It has been found on a range of conifer species, but pine (Pinus) are by far the most common hosts, with Corsican pine, lodgepole pine and Scots pine all now affected. Defoliation can continue year on year and gradually weaken the tree, significantly reducing timber yields. It can also eventually lead to mortality.Symptoms are first seen at the base of the crown on older needles. Infected needles typically develop yellow and tan spots and bands, which soon turn red. As the disease progresses, the ends of the needles then turn reddish-brown whilst the needle base remains green. It is within the red bands that the small, black, spore-containing fruit bodies tend to be found, with symptoms being most apparent in June and July. Spores are released from the fruit bodies during this period, leading to infection of the current year's needles. After this point, the symptomatic needles are shed, and branches can have a typical 'lion's tail' appearance, with only a tuft of the recently infected current year's needles remaining at the branch ends. This defoliation can continue year on year and gradually weaken the tree, significantly reducing timber yields and causing mortality.
• Dutch elm disease first appeared in north-west Europe around 1910. By the 1940s this first epidemic had died down after causing losses of 10—40% of elms in different European countries. The late 1960s brought the beginning of a second and far more destructive outbreak of the disease. The new outbreak was caused by an entirely different, far more aggressive fungus (Ophiostoma Novo-ulmi) which had been imported into Britain on infected elm logs. Horse chestnut bleeding canker
• Fungi:- Gendarme, Bracket fungus and Honey fungus.
• Massaria - Plane trees can be prone to a fungal disease called Massaria. This problem is mainly found in busy urban areas and can cause branches to decay or even fall off. There are a few ways to treat the problem and I will determine and implement the best solution.
