Various cultural methods have been used in an effort to control the size of the tree canopy in order to facilitate high density planting of peach [Prunus persica (L.) Batsch cv. June Gold] trees. Pruning and chemical growth regulation have been possible control methods to tree growth. Mefluidide, [N-{2,4-dimethyl-5-[[(trifluoromethyl) sulfonyl]amino] phenyl} acetimide] , a growth regulator, was applied to peach trees at 0, 0.24, 0.48, 0.96, and 1.92 g/liter in H2O 26 May 1978, 2 months after transplanting. The mefluidide treatments resulted in shorter, narrower trees with smaller trunks and increased axillary branching as the concentration increased. Phytotoxicity was rate-dependent and included leaf tip necrosis and epinasty. The 2 lowest rates were reapplied 21 May 1979. By September 1979, the 0.48 g/ liter treatment resulted in a shorter tree with increased lateral branching and the 1.92 g/liter rate caused increased branching. There was a trend of delayed and concentrated bud development with no effect on number of flower buds in 1980 by mefluidide treatments.
