Chemical control of fruit set and June drop in young Golden Delicious apple trees


, : Chemical control of fruit set and June drop in young Golden Delicious apple trees. Acta Horticulturae (80): 199-205

Young Golden Delicious trees were sprayed with PP 528 (ethyl-5(4-chlorophenyl)-2H-tetrazol-2-ylacetate) for 2 seasons in succession when shoots were 15 - 20 cm long. The treatment resulted in: (a) reduced shoot growth; (b) reduced cross-sectional area of the trunk, and (c) increased number of feathers. Half of the treated and control trees were pruned prior to full bloom in the third season.
