Question: peach bubbles

my peach suffers from bubbles what can i do during this time to remedy?

Answer: peach bubbles

Dear Chiara,
the bubble of the peach tree is one of the parasites that develop more often on these saplings, from which only some particular varieties, not particularly sensitive, are exempt; with the name bubble of peach means a mushroom, which lives on the plant throughout the year, showing a parasitic action only in spring, the mushrooms pierce the leaves and colonize them, causing a reddening of the leaf blade, which also tends to to become thick and fragile, almost crunchy if crushed; the affected leaves are no longer able to perform photosynthesis, and therefore the plants affected tend to perish, or even simply to lose their fruits; sometimes the bubble, in addition to the leaves, also affects flowers and fruits, irreparably ruining them. Once the leaves have been ruined by the bubble, it is not possible to heal them, making them turn green again, so the individual affected leaves should be detached from the plant and destroyed, because they contain the fungus spores. It is essential to do treatments on the diseased plant, so that the bubble does not appear even the following year; if it is a matter of a few affected leaves, the infection can be stopped and prevented from spreading to the rest of the plant; if instead there are so many affected leaves, it is hoped that the defoliation favors the development of new healthy leaves, to keep the plant alive; In both cases, it is important to treat the plant with a specific fungicide against the bubble, so as to kill any fungi that are still present. In addition to this, further interventions will be carried out on the nearby plateau and plants using Bordeaux mixture (or other fungicide against the bubble) in autumn, immediately after defoliation, and at the end of winter on the buds. Consider that the bubble mushrooms develop in conditions of high humidity and low temperatures, which at the time of inoculation must be less than 10-15 ° C; therefore a very rainy spring, with a cool climate, highly favors the development of the bubble, which tends to stop its development cycle when the heat arrives. If therefore the climate in late spring should become warmer and less rainy, generally it is not necessary to practice a treatment, which will instead be practiced in autumn, around November, and even in late winter, to prevent the fungus from getting back into action with the arrival of spring and a cool, damp climate. Generally it is not infrequent that plants severely affected by the bubble do not produce fruit in the year of infection.
