These three examples of successfully solved phytopathological 

 problems chosen from different departments of plant industry must 

 suffice; they could be multiplied many tmes, for I know of no crop 

 of cereals, textiles, fruits, vegetables or fodders of any kind outside 

 the tropics, or of any of the more frequent decorative plants to the 

 diseases of which some attention has not been given by phytopathol- 

 gists and for the control of some of which in nearly every instance some 

 measures have not been devised. 



Summarizing, I would say that the status of plant pathology is 

 measured by an ardent spirit of research, and an inspiring array of 

 beneficial achievements. 



What now can be said of its outlook ? A clearer conception of the 

 nature of the immediate tasks of plant pathology will be gained by an 

 analysis first of data on current losses from plant diseases.
