Growth Regulators for Management of Fruit Production on American Sweetgum    (View PDF)

Thomas J. Banko and Marcia Stefani

Abstract: Arborists concerned with management of undesirable fruit on Liquidambar trees in urban areas can treat the trees at time of flowering with Florel (ethephon) f or effective reduction in fruit formation. Atrimmec (dikegulac-sodium) also reduced the number of fruit produced; however, it is not currently labeled for this use. Florel reduced fruit formation by 87.7%; Atrimmec by 57%. Trim-Cut (mefluidide) did not significantly reducefruitformation. Growth regulatortreatments may be justified in certain locations to manage production of undesirable fruit.
