DISCOVERY OF TAKE-ALL IN THE UNITED STATES.
The presence of take-all on winter wheat was discovered about the
middle of April, 1919, through a report from the county agent of
Madison County, Ill., that wheat near Granite City was being severely
injured by some disease. Later this disease was found in other parts
of Illinois and in Indiana.
Shortly after the discovery of this trouble the name " take-all"
was applied to it tentatively on account of certain characteristics
which it possessed in common with the Australian take-all of wheat.
More extensive field and laboratory investigations indicate that it
is different from the Australian disease, as it is generally understood
to occur in Australia. However, until the cause of the type of disease
occurring in Illinois and Indiana has been determined, the tentative
use of the name "take-all" is continued.
ECONOMIC IMPORTANCE.
Under conditions favorable for its development, take-all may
cause considerable damage. In the spring of 1919 some of the fields
in Madison County, Ill., were so badly affected that they were plowed
up and planted to other crops. In one case a 40 per cent actual
reduction was caused in the total yield of grain in a 50-acre field in
1 All the field experiments for the control of take-all have been conducted on fields in the "American
bottoms" of the Mississippi River near Granite City, Ill., in cooperation with the Illinois Agricultural
Experiment Station. Certain laboratory and greenhouse studies have been conducted in cooperation
with the department of plant pathology at the Wisconsin Agricultural Experiment Station. In 1919
the field-laboratory studies were conducted in the laboratories of the Missouri Botanical Garden, St. Louis,
Mo., through the kindness of Director George T. Moore and Dr. B. M. Duggar. In 1920, through the courtesy
of Superintendent L. P. Frohardt, the field-laboratory studies were made in the laboratories of the Granite
City, Ill., High School.
