Answer: how can I cure my cedar?

Good evening, my cedar (conifer) has the "sickle of the hawk" caused by the fungino "chiodino". Are there any remedies? and if so what? Thanks

Cedar: Answer: the tack

Dear Mario,
the Chiodini, despite their interest in the kitchen and the name so pleasant, are real dangers when they occur in the garden; the scientific name is armillaria mellea, and it is a fungus that survives in the ground, and widens underground, looking for roots to colonize; through the roots the fungus rises towards the stem of the trees, where it survives below the bark; when we notice the symptoms of the infestation, there is now nothing more to do.
There are no products capable of eradicating the armillaria, once it has attacked a plant, it kills it; once the wood is dead, the armillaries, from parasites, turn into saprophytes, and feed on dead wood, until it consumes everything; then they move into the ground, looking for other "preys". These are organisms that form very large colonies, and that develop very slowly, so from the moment a plant is attacked, several years pass until complete death. In addition to this, the armillaria survives for a long time in the ground, even when the initial prey is completely disappeared, and also when a sick tree is removed, as vital fungi can remain even in small portions of roots.
So the only thing you can do is to eradicate your cedar before it dies and clean the soil of mushrooms. This type of intervention is generally practiced using antagonist bacteria, which you can find in specialized shops, or in agricultural consortia; there are no pesticides that have proven effective against nails.
These mushrooms develop freely in the undergrowth, because they act as scavengers: they attack the suffering or dying trees, kill them and free the wood from their wood, so as to leave room for new plants. In general this type of parasites, in the garden or in the orchard, attacks trees that are already suffering for some reason; if instead the armillaries develop on healthy organisms, generally it is because they were already present in the soil, before you planted your cedar.
