In the present study, the behaviour of some old and new apricot varieties, grown in an integrated orchard in Bucharest Area, is presented. The apricot orchard was planted in 2008 and in 2017using Romanian and foreign varieties grafted on Mirobolan, Myrobalan 29C, Saint Julien A and GF 677. The planting distances varied from 4.5 x 3.0 m to 3.5 x 2.0 m and several canopies were formed: Drapeau Marchand, Simple Palmette, Mikado, Parallel U and Trident. High concrete poles with 4 lines of wires, was made as trellis system for the trees planted in 2017. The land was maintained covered with a mixture of perennial grasses on the interrow and clean with herbicide on the row. Drip irrigation was applied for the 2008 orchard and micro sprinklers were used for the new orchard. Leaves were collected at the end of the growing season (late October) and the incidence of the bacterial disease was measured using a scanner and the WinFolia Software. In the same time the leaf are was measured. The results showed that the intensity of the bacterial attack was influenced by the variety, and surprisingly by the canopy.
