IMPORTANT NOTE ON NEMATODE INJURY 
AND COTTON WILT 
During the early and middle part of the 1949 cotton 
growing season, we received reports from farmers that their 
cotton was dying from wilt. We sent one of our plant disease 
specialists to examine the fields where damage had been re- 
ported, and found that the trouble was caused by root knot 
and meadow nematode injury instead of wilt. 
The unusually warm weather during the last winter ac- 
counted, in a large measure, for earlier, more vigorous 
nematode activity. These small, eel-like worms, about one- 
fiftieth inch long, feed on and burrow into the roots of cotton, 
and most of the other field crops, interfering with the taking- 
up of water and fertilizer from the soil, and the movement of 
these materials in the roots and up the stems of plants to the 
leaves where they are used in the manufacture of food for the 
plant to thrive and grow. As a result of nematode injury, 
plants are stunted and sometimes killed and yield and quality 
of cotton reduced. 
Nematode infestation may be greatly reduced by crop rota- 
tion and use of a non-susceptible crop such as crotolaria, early 
destruction of stalks by plowing under and the use of chemical 
soil treatments. 
FUSARIUM WILT is widely distributed throughout the 
cotton belt from Texas and Oklahoma eastward, and is partic- 
ularly severe in the sandy or light, acid soils of the Coastal 
Plain that are especially deficient in potash. Diseased plants 
may be recognized by the stunted, yellow appearance accom- 
panied by dying of the leaves which usually starts toward the 
top and continues downward. A brownish discoloration is ob- 
served when the bark of diseased plants is peeled back, and 
dark streaks are seen in the woody part throughout root and 
stem. 
VERTICILLIUM WILT usually prefers alkaline soils, and 
its damage is more in evidence during and immediately follow- 
ing a cool, rainy season. Field symptoms are similar to those 
of Fusarium wilt, and laboratory study is usually necessary 
to differentiate the two.

COKER 
COTTONS 
Our Coker 100 Wilt Resistant cotton has been bred to produce maximum 
yield on soils infested with Fusarium wilt, and it has some tolerance to 
Verticillium wilt. However, due to the development of apparently new races 
of wilt, complicated by adverse seasonal conditions, improper fertilization 
and the presence in many instances of nematodes, no conscientious breeder 
can guarantee any wilt resistant cotton to survive 100% on any wilt in- 
fested soils. 
RED HEART TRADE MARK ON ALL BAGS OF 
GENUINE COKER’S PEDIGREED SEED 
Our seed are all sent out in bags labeled ‘“COKER’S PEDI- 
GREED SEED” and bearing our registered Red Heart Trade 
Mark. Each bag also bears our O.K. tag and is officially sealed 
before leaving our warehouse. No seed is genuine “COKER’S 
PEDIGREED SEED” unless it bears our official O.K. tag under 
seal and our Red Heart Trade Mark. Protect yourself by in- 
sisting upon having only seed bearing our official O.K. tag 
and registered Trade Mark. 
OUR RESPONSIBILITY 
Our seed are all carefully tested for germination and purity 
before shipment. Attached to every bag of seed we ship is a 
card on which is printed the percentage of germination and 
mechanical purity of that particular lot of seed. Under no cir- 
cumstances, however, can we be responsible for the germina- 
tion of the seed after they have been planted for there are 
many reasons for imperfect germination of planted seeds other 
than their vitality. In no case, do we give any warranty ex- 
pressed or implied as to the productivity or performance of 
our seed. 
EFFECT OF GROWING CONDITIONS 
Our descriptions are based on the actual records that our 
varieties have produced in our tests, and they will show the 
same characteristics elsewhere under the same conditions. 
Drought or POOR CONDITIONS will result in a reduced 
yield and poorer quality—no matter what variety is planted.
