The cherry tree in Italy

Cherry is a fruit tree quite common in Italy, although it has Asian origins. It has been brought to Europe for so long now that it has selected native varieties. In its natural state the plant reaches even fifteen meters, but it is good to act with strategic pruning in order to make the harvest easier and concentrated. Moreover, periodic pruning and care and attention towards the fruit tree decrease the chances of appearance of cherry diseases. The main problem of cherry diseases и that damage the crop making it unsellable and, in extreme cases, inedible. Prevention, like all things, can help a lot to reduce or avoid damage.

The black aphid

For lovers of plants and gardening, surely the black aphid (scientific name Myzus cerasi) will result as a known enemy. In fact, the aphids affect numerous plants, especially young ones, sucking the sap and ruining the leaves which consequently will appear yellowish and rolled up on themselves. As for the cherry trees, the black aphid strikes shoots and leaves very frequently. Given that the cherry diseases they trigger are so clear and recognizable, you can immediately proceed with a therapeutic treatment. There are various types of them on the market, but it is obviously a good idea to use a fairly natural product that is also admitted in organic farming so as to be 100% sure of respecting both the plant and those who will eat it.

Cherry fly

The cherry fly aesthetically is very similar to the common fly and has the defect of laying the eggs inside the not yet ripe cherries, also because it is attracted by the yellow of the unripe fruit. The first negative effect is the yellowing of the drupe, after which the larvae begin to come out and all the fruits fall out. So it is easy to understand how devastating the attack of this fly can be and therefore it is necessary to intervene suddenly to counter it. The first thing you can do is to hang mechanical traps on the trees from May to June. These traps are yellow, because they attract the insect, and very cheap as they are simply made up of an adhesive disk. If you do not want to use chemical insecticides, absinthe can be used as a natural repellent.

Cherry diseases: Iunghi

Mushrooms can cause very annoying cherry diseases, such as the corineum, which is carried by the Stigmine carpophila. This is recognized by rather evident symptoms, in fact on the leaves appear some red-violet circular spots. These spots are initially surrounded by a clear halo which later turns to red and then to black. These spots can also be one centimeter in diameter and in the long run they also blacken and fall. As a result the leaf appears pitted. Small holes are also present on the twigs and on the fruits that eventually detach from the tree without having completely completed the maturation. Unfortunately when the infection is in progress nothing can be done to eradicate it, but it can only be done to reduce the damage. In any case, there are two anti-fungal treatments: one in the fall (with the leaves falling) and one in the spring (with the opening of the buds).
