Peach with yellow dots

Question: what affects my peach tree?

Good morning,
I bought a peach nano this winter, it bloomed very well in the spring, it started to bear fruit and developed a lot.
Lately, however, I have noticed that on the trunk and on the branches there are yellow spots followed sometimes by larger dark spots. I tried to touch one of these larger spots and broke, there is white powder inside.
Of all the fruits that had only 2 they turned into peaches (still on the plant and well developed).
Apparently the plant looks healthy, the leaves are beautiful and green, but the fruits have all fallen after they dried ...
Do I have to worry? Is it perhaps a type of plant fungus or maybe an excessive amount of fertilizer (I used a long-release granulated horn)?
Thanks for the help, greetings

Peach with yellow dots: Answer: peach diseases

Dear Christian,
your peach tree is very young, for this reason it is normal that it has not managed to complete all the fruits, it often happens that a young fruit tree produces a lot of flowers, which are all pollinated; but later, the need for the foliage and foliage (due to the fact that the plant is young) leads the sapling not to have sufficient "energies" to complete all the fruits, which then fall. Often it happens that in the early years everyone also falls. Clear that, a good fertilization and regular watering in the spring period, above all between the flowering and the production of the fruits, can favor the setting of a greater number of peaches. Avoid excesses, however, and water only when the soil is dry, or when the climate is particularly dry. As for the spots instead, a lot depends on the dimensions they have, if they are small specks, like pinholes for instance, it could be cochineals, or other insects; if, on the other hand, the spots are larger, they could be fungi or molds. In the first case, do an autumn and a late winter treatment with white oil; in the second case, it regularly practices (about every month) copper-based treatments.
