CHBMI-THINNINGWITH,AIrlINES IN THEDORMANT SEASON 429 Robert R. MorrowJ. "Hardwoods Cons1derab1eearly work in chemi-thinn1ngbSrdwoods was reported in 1959 (3). At that time the importance of a eqm,plete frill for dormant season deadening of most NortheasternU~ted States species was stressed. Top-kill was cllousedby adding cil~cal to the frill, . to make a zone of dead wood. Successful chemi-Wdles were made with 2,4,5-T in kerosene, 2,4-Din kerosene, and .rosene alone. The former chemical caused a wider girdle and appea3d to hasten topkill by as much as two years1n comparison with 1'2,4-D and oil alone. Wiant and Walker (4) have recently confirmed t~ Glil alone is sufficient to cause top-kill when e4ded to frilJ.s.··' In recent years there has been considerable-;I.nterest in the performance of amines of 2,4-D and 2,4,5~ in ~arison with esters. Such interest is spurred by reports that top-k:1.J.a., especially of oaks in the growing season, has resuJ.ted from aminee4D partial cute (some' li terature reviewed in reference 3). Comparatiw tests of amines, , esters, and oil were made in 1957 aniI. 1958 on a-.riety of species in woodlots in southern New York. All chemica1lf rwere applied in a complete frill at a rate of 2;"3 ml. per inch of,·tiameter. Most treatments. were made in October and November; a few W2'emade in February •. Table. 1 gives the approximate .t:tmerequired for -~b percent of the chemi;"girdled trees to be 90 percent top-ld.lled~· In mo@ttrees ,that required two to four YeEll'Sfor top-kill l there" was little kill the first year. Occasional treg'cling to life for many years, even though completely girdled, prerilliably thr01.1gh root grafts. In general there was little difference l!Ietween trea.tments in the time required for top-kill. A few cases 'Of live wood bridging girdles were found in the 100(1 ahg ~,4-D amine1treatment. These occurred on large vigorous trees, mainly red map;ij!. This may have resulted from polilr spreading and transJ.ocation cStamine in water at near freeZing temperatures. On the other hand, kerosene s];:reads and soaks into woody tissue rapi~ .at low temperatures. lAssoc. PrOf. of Forestry, Department .of Conservation, Cornell University.
