A method for administering fungicides into apple trees using a pressure injection technique is described. Ten or 2.5 g of thiabendazole (TBZ) dissolved in acidified water was infiltrated into the trunk of 16-year-old apple trees. The fungicide accumulated initially in the vicinity of the injection point, forming a reservoir of TBZ inside the plant. Subsequently, a secondary distribution occurred, resulting in a gradual upward migration of the fungicide. Forty-two days after injection of the higher dose, TBZ was detected in the top branches and leaves of the tree.
