ing evidence that tobacco root
rot. one Of the most destructive
diseases OF Kentucky's principal
crop. can be controlled by the use
Of disease resistant strains of to-
Eacco will be presented to- grow
ers and other interested persons
who gather here Tor the field
meeting to be held on the Ken
lucky Agricultural Experiment
Station farm, August 10, it has
been announced by those in
charge of the program.
This is the third year that the
work has been carried on ut the
station farm and results already
obtained indicate that the selec-
ton and development Of root rot
resistant strains OF hurley offers

age caused by the trouble thereby
saving hurley growers immense
sums of money each year. A
part OF the field meeting will be
devoted to tour of the station
plots of which resistant strains of

from the resistant varieties have
made a normal growth and are
healthy and strong because of
their ability to withstand the eff

from the commonly grown varie-
ties are small and undersize.
The effects Of root rot on grow
ing tobacco is to be seen in hun
dreds OF hurley fields at this time
Of the yea, tobacco specialists
Of the station say. The effect is
especially marked where the leaf
has been grown on the same land
for two or more years. In many
I fields it is common to see some
! plants that have grown rapidly
while others next to them are
weak and stunted. Many grow
ers do not recognize the trouble
as a distinct disease when they
are unable to obtain uniform
stands of the crop.
i Up to the present time those in
charge of the experiment have
worked with large number of
root rot resistant selections from
which the disease strain eventu-
ally will be developed. Eight
common hurley varieties also are
being grown on a basis of COM
parison. Tests also have been
started in an attempt to develop
resistant varieties. OF dark tobac-
