“…Investigations conducted with aqueous growth regulators suggest existence of significant regrowth variability among tree species pressure injected with any concentration of a plant growthregulating chemical (Domir et al, 1982; Roberts et al, 1 979). There may be several reasons for lack of uniform regrowth among chemically treated trees, including heredity, physiological vigor of the tree canopy, size of the tree, uneven distribution of chemical among limbs of trees, and stress influences such as air-pollutants and moisture deficits (Domir, 1982;Domir, 1981 and1983). The timing of chemical application may be another critical factor in achieving consistent growth retardation without causing adverse damage to the trees.…”

Three-year-old London plane (Platanus acerfolia) trees pruned at 5 different stages of plant development were injected with dikegulac [2,3:4,6-bis-0)1-methylethylidene)- 0(-L-xylo-2-hexulorfuranosonic acid)]. At the end of the growing season, sprout length, number of new sprouts, and phytotoxicity were determined. Maximum growth reduction with minimum foliar damage was obtained on injected trees pruned at half-leaf development stage. Even though greater growth reduction was obtained on injected trees pruned at fullleaf development stage, the phytotoxicity was unacceptable.
