Twelve years a60 the art and science of aerial apj.Li.cat.Lon of herbicides was unknown. Six years ago it was in its infancy, only having been attempted experimentally on limited areas. llow, 1961, silvicultural weeding of forest stands by aircraft is coming into its own just as cotton dusting did a number of years ago. Aerial work ap1-'eals to most foresters. They see in it the opportunity to cover large acreat.,es in a short period of time with a gr-eat-Ly reduced labor force. It fits in with the era of mechanization that is filtering through the dimly lit forest aisles. d,v company, Hiwassee Land Company, began its aeri.al spraying program back in July of 1955. Actual negotiations and pro cedur es were worked out with t.l.e contractor several months prior to that. The first year's work was not alto~ether satisfactory, but we believed the technique showed pro­ 'iLise. That first year, 1955, we sprayed 2,000 acres of competing low ~rade hardwoods on the Cumberland plateau. The following year we sprayed 4,U78 acres. During the summer of 1957, Hiwassee sprayed 3,635 acres. In lS58, 6,846 acres, in 1959, 7,900 acres, and in 1960, 17,050 acres were call of t.l.i.s aerial sprayed. This totals for another 24,000 acres. met-hod of silvicultural 41,509 acres. So you can see weeding. 1 1ne that present we think year's pretty In the course of six years of large scale aerial applications of herbicides, it follows that we are bound to have made some observc ..tions that may possibly be of some value to others. Although the hills and mountains of east rl'ennessee, no ct.h Georgia, and north Alabama have presented so.ne difficult problems, these same problems exist elsewhere, and tLe difference is one of degree rather than character. Anyone of the items to be presented in tbis paper is material for a paper in itself, so, of necessity ,covera.ge is limited. plans well Ore,d.nization and freparation The organization of a production size aerial spr-ay.i ng oper-at.i.on i.s of fundamental .impor-t.ance , It can either make or break the entire j0b.e personally favor the I1total contract" approach.
