Marked changes IN the method of
controlling tobacco hornworms may
be brought about in the hurley sec
ton Of Kentucky as a result Of ex-
periments which have been conducted
along this line during the last few
months by leaf growers in this sec
ton Of the state who eo-operated
with the College Of Agriculture ex-
tension division and the United States
Department 81 Agriculture. in the
opinion Of County Agen; W. X. Cab

Results obtained in the 20 expert
ments indicate that il may be profit
able for growers 20 change from the
long-established use Of paris green
and adopt dry powdered arsenste Of
lead as a control for the insect pests.
he said
Fifty per cent q the growers on
whose farms the experiments were
conducted have turned from the use
Of paris green and adopted the dry
arsenate as a control for the insect
pests. while more farmers are ex-
pected 20 adopt the latter practice
next year as soon as their supply Of
paris green IL exhausted. Joseph
Milan. special field agent in ento-
mology from the United States De
partment Of Agriculture who was in
charge Of the experiments. said be-
fore leaving for his station in Clarks-
Vile. Tenn, al the close Of the work
Sale Of Guns Increases
An increased sale Of guns for APP
plying te arsenate. together with an
increased use Of the material. has
resulted since the experiments were
started. Mr.. Milan added. One local
dealer has disposed Of eight guns.
while another dealer who never had
the dry arsena,e in stock before has
sold more than 500 pounds Of Il as
result Of the experiments.
For some time. the use Of paris
green has been advocated as the
most reliable control for the horn
worms. which annually give tobacco
growers considerable trouble. Data
obtained in the experiment, however,
indicate that better results are OBJ
tanned through the use Of the dry
arsenate.
Some Of the more important advan-
tages to be gained through the use
Of the powdered arsenate were out
lined by Mr.. Milan before he left.
Chief among these was the fact that
this material does not injure the
plants unless applied in extremely
heavy doses. II also remains effec-
tive longer and can be applied when
the planst are in later stage Of
growth, thus making Il possible to
control the late broods Of worm.
The arsenate also does not injure
the operator and. therefore. Is not as
dangerous 10 use As il paris green.
Another advantage is gained in that
the arsenate will Kill grown worms.
while paris green will not.
Four Pound. to Acre Used
Best results in the experiments
conducted in this vicinity were OBJ
iained by using the arsenate at the
rate Of obout four pounds an acre
and applying il with a gun equipped
with a fan blower, Mr. Milan said.
The relative value 81 the pars green
and the arsenate was compared in
each Of the tests. the paris green
being applied with a hand blower
very instance the latter material kill
ID a larger percentage of worms and
IN most eases remained effective long
r. without injury to the tobacco than
paris green did, he added.
In addition to the experiments con
iueted in this county, eight were car
lied on in Harrison county. Farm.
