Below is an overview of some known tree diseases , including sick tree treatment plan to prevent the spread of the contamination and a solution for the tree in question that prevents the removal of one or more ‘infected’ trees.
Bacterial fire is a contagious disease, which is relatively rare in view of the risk of contamination. Observation:
A tree with fire blight can be recognized by the wood that is colored purple, the buds and flowers die off and tree moisture is released from this. Bacteria fire occurs in species of the rose – apple – cherry family. The pear tree, hawthorn tree, (ornamental) cherry tree and related species can suffer from this.
If a tree has this disease, in many cases the tree must be cut down immediately. This must also be reported to the tree specialist of the municipality. When fire blight has hit the garden or the complex, then all the effort must be done to eradicate the disease.To this end, the Hearths must be cleaned up by cutting away the diseased parts of the plant , or in case of multiple damage to one tree by placing them on the ground or grubbing them up.
The fungus only affects elms. It is transmitted in Europe by the great elm bark beetle (Scolytus scolytus) and the small elm bark beetle (Scolytus multistriatus). The fungal infection starts in the ring last year of the tree and can spread to the entire tree through the wood barrel system.
The tree produces methyl, a gum flax to stop the growth of the fungus, but as a result of these vessels are also clogged, resulting in tree mortality. In the middle of the summer the leaf is, normally, fresh and green. A sick elm shows early autumn colors. The leaves turn yellow to brown and fall off. This starts with one branch and can enter-spread some weeks over the entire crown. Characteristic are the so-called pennants: bare branches with one or two withered leaves at the ends. With a sharp knife you can cut off part of a damaged branch.
In addition to the most rigorous method such as felling and incineration, a number of alternatives have been developed with the elm can be dispensed with. There is eg. a control method has been developed for a specific way so that the tree no longer gets sick despite a contracted infection. In addition, there is a method where the tree is preventatively infected with fungal infection.Both methods are not sanctifying, but the alternative, grubbing is even worse.
Fruit tree cancer is a fungal disease in which the cells and the juice flows from that spot. The rest of the branch or tree will therefore be off. The fruits can also be affected, which is called nasal rot. Fruit tree cancer is a well-known disease in agriculture, but there are also less sensitive or insensitive varieties.
This fungus, Nectria galligena, mainly occurs on apple trees. Dead spots develop on the wood and slowly expand until they enclose the entire branch or tree. Red dots appear around it in autumn. The wood under the dead spots is brown.In young trees or thin branches, the cancer site provides a barrier to the transport of moisture. The branch or tree then dies off. In older branches and trunks there is often enough space left to ensure this transport. You can find a great sick tree treatment expert at sick trees fort worth.
Fortunately, the cancer can be cut with a sharp knife. Important here is to cut deep enough and also to go into the living wood. If only a piece of mold remains, everything starts all over again. Cancer mainly has a grip on trees in poor condition. Scars of picked fruits and fallen leaves, but also pruning wounds, forked branches and traces of wild food are ideal growth bottoms for cancer. In general, the more vigorous the tree, the faster wounds become overgrown. Avoid excessively large wounds when cutting or treating them with an effective wound paste.
