OuIAHS Tic past SuulIHeI, ODScT-
walton was made of large num-
Der of tobacco fields in Beaufort
County with reference to tobacco
diseases mostly black shank,
Granville wilt and Nematodes
(root knot)-and the performance
of the disease resistant varieties.
1. The spread of black shank
was, greatly speeded up during
the growing season. 1t was esti-
mated that at least so percent
more fields were infested with
black shank in 1851 than in 1850,
and black shank was found scat
tered to all tobacco growing
neighbOrhoods in the county,
which leads one to think that the
spread of black shank is likely
to increase in 1852 over 1851.
A larger acreage was planted to
black shank resistant varieties in
the county in 1851 than ever be-
fore. 1t is estimated at least so
percent of the acreage was plant
ed to black shank resistant varie-
ties during 1851. Dixie Bright 1O1
was the predcminating black
shank resistance used witk Oxford
l second, and few fields of Dixie
Bright 102. In general, Dixie
Bright 101 performed very salts
factorily in that good yield of
cigarette tobacco and satisfactory
res lance was in evidence
throughout the county.
A careful check was made of
many fields where resistant varie-
ties did not live satisfactorily. Re-
suit of this check has important
significance to tobacco growers,
and the following conclusions are
listed below for farmers considera-
ton:
l. There is not resistant va
riety available today that can
be counted on to live 100 percent
on soils highly infested with
black shanks or Granville wilt.
2. There was a big difference
between: % tobacco after to-
baccO and e tobacco after corn,
even where resistant varieties
were planted. In most of the
fields checked that were planted
to resistant variety(s) with to-
baccO following tobacco as high
as 30 percent of the plants died,
and in few cases as high as so
percent of the plants died; while
on the other hand 80 to 80 per-
ctnt were standing up living
where tobacco followed corn. It
is to be understood that the re-
slstant varieties to black shank
and Granville wilt is NOT i'm
mune therefore, to be ON the
safe side, always follow tobacco
on land that was planted to corn
the year before or some other
crop like cotton, even if resis-
tant varieties are planted.
The recommended resistant va
rieties are as follows:
1. Varieties resistant to black
shank only: Oxford 1; Oxford l.
181; Vesta 80 and Vesta A.
2. Varieties resistant to Gran
vile wilt: Oxford &c and Dixie
Bright q.
8. Varieties resistant to both
black shank and Granville wilt:
Dixie Bright 1O1 and Dixie Bright
102.
Dixie Bright 1O1, Oxford /, Ok
ford 1-181 and Vesta a have about
the same resistance to black
shank. Vesta 80 and Dixie Bright
102 are highly resistant to black
shank.
Dixie Bright 1O1 is more adapt
ed to a wider range of soil type
than possibly any other variety,
especially on soils on the fertile
side.
Only certified resistant varieties
of tobacco seed should be planted.
DO NOT plant resistant variety
seed grown by local tobacco
grower, unless he grows certified
seed.
