BULLETIN No. 203 SEPTEMBER, 1921 



Tobacco Wildfire 



PRELIMINARY 

 REPORT OF investigations 



By G. H. CHAPMAN and P. J. ANDERSON 



Wildfire, a bacterial disease of tobacco which has appeared 

 in Massachusetts during the past two seasons, will unques- 

 tionably become a source of serious loss to growers unless 

 it is controlled. In nearly all, if not in all, cases where the 

 disease has been noted in the field it was found that the 

 infection originated in the seed-bed. The production of 

 healthy seedlings is therefore a matter of prime importance. 



This bulletin describes the symptoms of the disease, its 

 causes, and reports results of investigations on control.
