Advises burning stubble prior to plowing. ‘There is little 
doubt that what has often been called ‘Takeall’ was simply 
root fail, caused by a dry, hollow seed bed.”

He says “it [take-all] is now proved through investigation 
of this branch to be due to a fungus.” * * * “True take all 
* * * had invariably a special fungus at the butt of the stem 
or on the roots * * * so that the term [take-all] has now a 
definite meaning and applies to wheat plants which have suc- 
cumbed to the attacks of this particular fungus.” Diseased 
stubble was placed in sand in pots and wheat planted in the 
pots with it. “After eighteen days * * * characteristic 
brownish spots were observed on the young stems. * * * 
Microscopic examination showed the presence in abundance of 
the young mycelium of the Ophiobolus. After six weeks many 
of the plants were dead.” 
In December, 1900, samples of white head were sent to 
McAlpine, and he says that he determined the fungus re- 
sponsible for white heads and take-all.
