The second preventive treatment of peach and apricot trees is recommended for combating moniliasis, flaking, leaf black spots and defoliation. Spraying can be applied between March 20 and 30 when buds begin to swell. As solutions, you can choose Merpan 50 PU, Super Champ 250 SC or Topsin 75 PU.

The following treatment aims at combating diseases such as leaf leaching, lead disease, fungal scarring, and flaking. The treatment is administered between the pink button phase until near bloom and can contain substances such as barium polysurf, Orius or Folicur.

In the last decade of April, there is a treatment against leaf and flaking, as well as aphids and defoliators. The treatment is identical to the one before and it is retained when 10-15% of the flowers have shaken their petals.

In the first decade of May, spraying with fungicides and insecticides is carried out to combat leaf black spots, moths, peach worms and aphids.

Two weeks after this treatment, acaricide treatment is used if leaf black spots are observed.

Between May 15 and August 1, it is recommended to avoid spraying with organophosphorus solutions. If the appearance of the butterflies is observed after the flowers are shaken, a treatment against apple worms is needed. For this treatment, one of the following insecticides may be used: Calypso 480 SC, Diazol 50 EW or Sumicidin 20 EC.
