Chemi-pruning, a new term in American forestry, consists of deadening the lower branches of hardwood trees with chemical spray. The branches are then allowed to decay and drop off. Slash decay studies indicate that this should happen in 4 to 7 years when branches are 2 inches or less in diameter. Three spray mixtures applied with a shoulder-mounted mist blower killed branches to a height of 16 to 20 feet on tree stems. The technique proved safe for susceptible species like oak and is successful on resistant species like maple when used from mid-June to early September. Both 2,4,5-T and an invert emulsion of 2,4,5-T and 2,4-D were used at costs ranging from $5.10 to $6.17 per acre. Chemi-pruning hardwoods is an economical method of improving tree quality which should increase the return from growing hardwoods.
