In the table below the results of the experiments are reduced to 

 percentages calculated on the totals in each plot. 



These experiments would tend to indicate that (1) formalin lias 

 no beneficial result on the disease; (2) the plots treated with quicklime 

 were slightly better than the controls but other experinirnts would 

 be necessary before arriving at any definite conclusion.

The fungus causing this disease is essentially a soil organism. 

 Methods of control should hence aim at preventing soil from becoming 

 contaminated with the fungus rather than getting rid of it when once 

 in the soil.
