Murrill: The Fruit-Disease Survey 



53 



experiments included not only a tobacco strain test but also 

 studies on various fertilizers and rotations. In connection with' 

 the field studies, difficulty has been encountered with the root-rot 

 disease caused by Thietavia basicola and the plant pathologists 

 of the Pennsylvania Agricultural Experiment Station have been 

 called in to assist in testing the various strains of tobacco for 

 resistance to this disease. This season, six strains were being 

 tested on infested and noninfested soil and marked differences 

 were noted. One strain is apparently highly resistant, though not 

 immune, to root-rot. It will produce a good crop beside other 

 strains which will be a total failure. 



Dr. Lyman was fortunate in having such able and obliging 

 associates on his committee of arrangements. Fromme was in 

 charge in Virginia, Giddings in West Virginia, Temple in Mary- 

 land, and Orton in Pennsylvania. Dr. Waite represented the 

 Department of Agriculture.
