Experimental Spraying in 1960
. 'h'firf such spraying was done in the Medford
BLM district in 1960 on an experimental basis with
participation of the research staffs of the forest service
a?,h r" Sf'euniversity, Ross Youngblood, manager
of the Medford BLM district, said the BLM has found
it practical to use herbicides on brushland containing
young conifers in the understory as a result of the trial
sprayings.
Through the proper use of formulations, conifers
are virtually unaffected, and by controlling the brush

Growth is most notable the second season after spray
ing. Chemicals Used by BLM
Chemicals used by the BLM were low-volatility
esters of herbicide suspended in a water-based emulsion
of white diesel oil. The forest service used 2-4-D spray
on its 180 acres in the Applegate district. The BLM
sprayed 700 acres.
The forest service treated two 90-acre tracts with
different applications.
On one tract, eight gallons per acre were used, and
on the other, six gallons per acres were used.
On Elk Lumber Company Land
The forest service heliport was on land owned by
Elk Lumber company, which had given permission for
its use. The Hiller helicopter used by the forest service
made 21 flights in about three hours to complete the job.
The 700-acre spraying conducted by the BLM was
accomplished in four days.
Aerial spraying of herbicides to control brush is an
other phase of a program to expand the productivity of
forest land for future generations, forestry officials noted.
