Description
Summary:It is estimated that electric utilities spend more than $1 billion per year on line-clearance tree trimming. Repetitive tree trimming can be reduced or delayed with the use of tree-growth regulators (TGR), chemicals that can alter tree growth or regrowth by interfering with various physiological processes. There is a national shortage of trained line-clearance tree trimmers, and TGRs may be used in the future as a replacement for unavailable labor. The typical tree to be treated with a TGR is a streetside tree in an urban or suburban setting that is beneath an overhead conductor and generally is between 10 and 30 inches in diameter at breast height. Injection of trunk or root flare is the most common TGR application technique.
