AB Three hundred trees under utility electric lines were selected in 1984 in the communities of Yonkers, White Plains, and New Castle in Westchester County, New York to test the effectiveness of Atrinal (dikegulac) in controlling tree regrowth following trimming. Atrinal was applied to plane trees, red maples, and Norway maples by trunk injection after trimming. During the first growing season after Atrinal treatment, the average sprout length reduction was 48.3% for plane tree; 23.9% for red maple; and 33.3% for Norway maple. In 1984, Atrinal injection reduced the average length of longest wound sprouts for plane tree 53.6%; red maple 41.2%; and Norway maple 29.1%. The variability in tree regrowth noted among species may be due to different uptake rates of Atrinal, amount of crown removal, climatic factors, and tree health prior to treatment.
